What Is Non-Destructive Excavation?

Tue, 01 Jul 2025 02:11:36 GMT

What Is Non-Destructive Excavation—and When Should You Use It?

In construction and civil works, knowing exactly what’s underground before you dig isn’t just a good idea—it’s essential. That’s where non-destructive excavation (NDD) comes in. At Excavac , we’ve been using this method on job sites across Sydney, the Blue Mountains, Illawarra and the Southern Highlands for over 20 years. Here’s a breakdown of what it is, how it works, and when it’s worth considering.

How It Works

Non-destructive excavation — often referred to as potholing or hydro vacuum excavation — uses pressurised water to loosen the soil, which is then vacuumed into a holding tank on our trucks. It’s a fast, clean and accurate way to locate underground utilities like gas, water, sewer and electrical lines.

Because it doesn’t involve mechanical digging, NDD greatly reduces the risk of damaging these services. This is especially important on older sites, where plans may not be accurate or where multiple layers of infrastructure have been added over time.

When to Use It

NDD is ideal for:

Locating underground utilities before major excavation
Digging near sensitive infrastructure like fibre optic cables or high-pressure gas lines
Tight access sites where traditional digging isn’t practical
Environmental or heritage sites where disturbance must be minimised

We also see it used more frequently in urban areas where underground congestion is high and the cost of accidental damage can be significant.

Why It Matters

Aside from safety, using NDD can also save time and money. Identifying underground assets early helps avoid unexpected delays and makes project planning more accurate. It’s not about replacing traditional excavation entirely — it’s about using the right method in the right situation.

We’ve seen first-hand how a small potholing job at the start of a project can prevent major headaches later on.

If you're unsure whether NDD is the right fit for your job, feel free to get in touch —we’re always happy to offer guidance.

What exactly can (and what can't) a ‘sucker’ truck do?

Mon, 23 Jan 2023 23:50:24 GMT

Offering safe, efficient removal of all wet and dry waste products

There’s no doubt you’ve seen them on building, construction and industrial development sites around Australia, but one question we’re constantly asked is; what exactly can - and can’t - a vacuum (or sucker) truck do?

Naturally, it’s important to have informed and measured expectations to ensure you have the right equipment and labour on your building site so that things move along quickly and efficiently.

Essentially designed for suctioning various liquids into a tank for removal and safe disposal, a well-equipped and versatile sucker truck can be deployed in a wide range of industries and sectors.

Builders and site owners are normally required by a development consent to have adequate erosion control measures in place at construction sites, meaning there are mandatory regulations for controlling soil erosion including removing accidental spills of soil onto roadways, gutters and public thoroughfares.

This is where sucker trucks come into their own, providing a fast and safe method to get the job done without fuss, making professionally built and operated units a staple for the industry.

Used extensively in the construction sector, sucker trucks are also engaged in the petroleum, gas and mining industry for cleaning of storage tanks and spills along with removal of most wet material including drillers mud.

Sucker trucks can also be used for sewer pipe cleaning and septic emptying, clearing of storm drains, sewer lines and catch basins as well as just most projects requiring the removal of debris or liquids.

They’re equally at home when it comes to horizonal directional digging (ie: the installation of underground cables and pipes), utility location servicing and pot hole/post hole digging where safe and secure foundations are needed.

However, there are some areas where vacuum trucks may not be suitable, such as the clean-up of contaminant spills such as oil, petrol and other flammable fuels.

Similarly, when it comes to jobs such as pool excavations our advice is to explore your options. While vacuum trucks can certainly handle the job, normally the scope and extent of the work means manual methods may be more effective.

Expert identification of underground assets

Thu, 20 Jan 2022 04:12:14 GMT

Excavac specialises in identifying underground assets safely

One of the biggest challenges during an excavation is avoiding damage to any underground pipes electrical cables and conduits.

Hydro vacuum excavation (also known as non-destructive digging – NDD - or evacuation) is used to dig precision holes over and around these assets to expose them, is widely used in the construction, civil and utilities industries.

The benefits mainly involve the large reduction in risk compared to mechanical excavation, jackhammering and drilling. This is because it avoids damaging underground utilities, surrounding materials and provides a major reduction in noise pollution and disturbing the local environment.

Hydro excavation offers a way to:

Protect the asset and minimise the risk of damaging all underground assets;
Safely identify the asset to determine actual depth, size and material;
Reduce environmental impact with minimal surface disruption;
Allow trenching for conduit laying in high existing service areas;
Assist with minor and major civil works;
Provide a safe and cost-effective services location;
Allow for asset exposure, post hole digging, sign post digging, tree removal, optic fibre exposure and pit construction;
Reduce reinstatement costs; and
Reduce downtime associated with offsite NDD slurry removal and disposal.

Removing the risk or hazard of damaging the underground services is the main focus of any building work-site and using Excavac to safely identify these services is the safest way.

If you have critical infrastructure on your site such as fibre optic cables or high-pressure gas pipes or high voltage electricity cables, these also need to be identified before excavating.

To expedite the process around congested services without rushing the mechanical excavation and risking the project by a potential partial site flooding from a ruptured water pipe, then NDD is definitely recommended.

The same applies if are just looking to fulfil your duty of care when working around underground services and in turn, complete your obligations to your public liability insurance.

These critical services can be conducted from two to 30-metres.

Proudly Australian owned and operated, Excavac services the Blue Mountains, Southern Highlands, Illawarra, Sydney Metro and South Coast.

It has set the standard for more than a decade when it comes to NDD carried out by a team of qualified professionals operating a modern fleet of trucks and equipment and has been a trusted name to industry, government and private enterprise since 2007.

Underground utilities

Thu, 11 Nov 2021 23:48:12 GMT

Always more than meets the eye

An underground utility survey – as the name suggests – is a form of survey used to determine the type and location of subsurface utility infrastructure and is designed to create a comprehensive map for the installation of gas and water lines, communications and publicly owned utilities.

Getting it right, is vital for ensuring the limitations of a project from the start.

Accurate information and having the right people and equipment is a crucial part of planning, particularly when it comes to the installation of new works and excavation of potentially hazardous older utilities.

A lack of proper insight could lend itself to not only catastrophic damages of existing underground infrastructure and disruption to utility services (from what is usually a maze of poorly mapped cables and pipes) but also significant danger to those on site.

Traditional mechanical excavation methods are not only messy and labour intensive but can also seriously have a detrimental affect on the environment.

Today, the simplest and most efficient way to excavate an area safely, is through the use of non-destructive excavation (NDE) or non-destructive digging (NDD).

Employed across a wide range of markets including civil, environmental, geotechnical, design, utilities, infrastructure and facilities management sectors, the process can also help gather and verify additional data attributes such as type, size, material, configuration and offer a greatly reduced level (RL) of the exposed utility.

Using either pressurised water to mobilise soil, along with an industrial strength vacuum to simultaneously excavate soil with minimal environmental impact, non-destructive digging offers safer working conditions, is cost effective and eliminates many of the on-site risks. It can also be done in a fraction of the time compared with conventional methods.

From manufacturing to construction - mining, engineering through to public works and trade tenders, the advantages NDD technology supersedes older, more invasive and generally costly methods.

NDD ticks all best practice boxes

Sat, 03 Jul 2021 20:56:28 GMT

What we do and how we do it is important

Excavac’s hydro excavation services are used in a wide variety of industries in both remote areas and metro locations including municipal councils, construction and telecommunication industries.

The company provides vacuum excavation services to the construction industry, in early works and where services need to remain in place while work is undertaken.

Some examples include road and pavement building works, and general construction involving hydro excavation .

Strategic hydro excavation of only one portion of soil surrounding a power pole enables it to be straightened and the foundation reinforced without having it completely removed. Users of this service include power companies, utilities, and the construction industry.

Using non-destructive digging for core sampling minimises the risk of cross-contamination that could occur when traditional excavation techniques are used. This is essential for geotechnical and soil analysis prior to work or even post-works site remediation.

Utilities and services such as sewer, telecommunications, power or gas lines, often exist in the site where trees need to be planted or remediated. Non-destructive digging is an ideal and cost-effective solution to investigate the extent of root invasion without damaging the underground lines.

Excavac’s non-destructive digging technology is licensed by the Environment Protection Authority.

The technology reduces risks associated with conventional digging, and also closes the loop on industrial waste by ensuring that slurry produced by hydro excavation is reused as backfill whenever possible.

If you are seeking a non-mechanical excavation method that’s environmentally-friendly, non-invasive and non-destructive, Excavac is at hand to help.

Non-destructive digging (NDD) , also known as hydro excavation, works by blasting soil or other surfaces with highly pressurised water and air.

The pressure mimics the effect of mechanical digging, but because the water or air is focused on the target, it doesn’t impact the surrounding area, underground assets or tree roots.

After the soil is loosened, it is sucked up with other debris using a high-volume suction hose into the hydro vac storage tank.

NDD is a great option when excavating near underground services like sewerage pipes, gas, water and telecommunication lines. Mechanical drilling can be slow as the risk to surrounding areas is high, whereas NDD is safe and efficient.

Non-destructive digging is not only useful for potholing and excavation, it’s a safe method for areas with valuable underground assets, straightening power poles and obtaining soil samples with coring while reducing risk of cross-contamination.

The pressure system applied during non-destructive digging is significantly quieter than traditional mechanical digging equipment, which is important in suburban and metropolitan areas with residential properties and foot traffic.

NDD also ensures less mess than other approaches to digging, reducing clean up time, while saving cost throughout the project.

Detours and road closures are other inconveniences of infrastructure upgrades. Non-destructive digging can reduce the impact, with excavations taking minutes instead of hours.

The non-invasive method also ensures that underground assets are not harmed in the process, eliminating cost from potential repairs. Tree roots and plant life are also better protected from damage.

Best practice - best solution

Tue, 25 May 2021 02:38:24 GMT

Using non-destructive excavation methods is best practice

Using non-destructive excavation methods is the preferred method and regarded as best practice by owners and regulators to prove the existence and location of an asset.

Additionally, some owners have made it mandatory to expose assets before beginning any works.

Before beginning any excavation, it is recommended certified locators be engaged who have the requisite skills and appropriate locating equipment to locate underground infrastructures.

Some locators will have specific training to meet the requirements of a varied set of asset owners; while some asset owners may specify their own certified locators, who have had specific training and have access to specialised equipment to work on their infrastructure.

Non-destructive hydro excavation or vacuum excavation techniques are widely accepted as the safest method to expose or excavate underground assets for repair, remediation and clean-up work.

The technology serves several different purposes, encompassing civil construction work, rail infrastructure excavation, potholing/posthole digging, trenching, upgrading or removing underground conduits.

It is generally accepted as best practice for in site investigation, general construction and remediation works and on sensitive, safety aware industrial facilities such as refineries, chemical manufacturing and power sites.

The process usually involves using a hydrovac truck that offers a precise method of reducing the potential to damage and impact infrastructure, utilities, or cause injury.

Using this non-destructive technology can quickly, safely and economically provide a less invasive solution to all onsite soft excavation, clean-up and digging jobs, while minimising the impact to the environment, reducing disruption to surface activities and increasing the progress rate of an excavation program.

The benefits include providing asset protection through non-destructive locating of underground utilities/services and allowing identification without making physical contact with them.

Excavation can occur in areas otherwise inaccessible by traditional machinery. It also has minimal impact on surface activities and traffic flows.

For smaller jobs it is a faster, more efficient and cost-effective method than manual/hand excavation.

Proudly Australian owned and operated, ExcaVac has set the standard for more than a decade when it comes to NDD (non destructive excavation) and pot holing services carried out by a team of qualified professionals operating a modern fleet of trucks and equipment.

Servicing Sydney Metro, The Blue Mountains, Southern Highlands, Illawarra and the South Coast, ExcaVac has been a trusted name to industry, government and private enterprise since 2007.

Hydro-excavation applications

Wed, 16 Dec 2020 00:55:51 GMT

Where can hydro excavation best be employed?

The advantage of hydro excavation (in contrast to other excavation methods) is that it’s non-mechanical, so underground infrastructure such as gas and electrical lines, cabling and communications sub structures are not contacted mechanically, reducing the risk of damage.

It offers versatility, avoids the pitfalls associated with other techniques (such as air-blasting) and has the added advantage of using water as a lubricant, which helps to prolong the life of the excavation equipment by reducing wear on the vacuum hose and other components.

So? Where can hydro excavation best be employed?

Construction: Commercial and industrial facilities along with residential infrastructure can’t be started if the ground is not properly excavated. Since most sites are quite large, the use of traditional methods such as a backhoe is time consuming – making hydro excavation perfect for both big and small jobs.

Plumbing: Pipelines and sewers are mostly installed underground. To have effective, compliant subterranean work done (where soil needs to be excavated, hauled and restored), hydro excavation comes into its own.

Landscaping: Environmental improvements through beautification work and the planting of larger trees and flora means ensuring as little disruption to the environment as possible. Since the point is to beautify the space, it would be a contradiction to dig carelessly and damage the area using traditional methods when hydro excavation can do the job seamlessly and with greater efficiency.

Installations: Whether it’s road signs, traffic lights, sign posts or sprinkler systems, they all need to be installed by excavating the ground. The use of high pressurized water to cut through soil and create accurate and precise holes makes for precise, time and cost saving efficiencies.

Proudly Australian owned and operated, ExcaVac has set the standard for over a decade when it comes to hydro excavation and non-destructive digging, with a team of qualified professionals operating its own modern fleet of trucks and equipment.

Servicing Sydney Metro, The Blue Mountains, Southern Highlands, Illawarra and the South Coast, we have been a trusted name to industry, government and private enterprise since 2007.

A money-saving investment

Wed, 04 Nov 2020 23:26:56 GMT

Environmentally friendly with reduced reinstatement costs

The problem: You need to expose buried utilities safely and conveniently while avoiding any damage to underground pipes and cables.

Naturally, you need to keep workers, employees and the public out of harm’s way at all times, plus any work needs to be efficient, clean and affordable.

The solution: Hydro Excavation.

Also known as non-destructive digging (NDD), hydro excavation involves using powerful jets of water to loosen the substrate before removing any debris by sucking it up into an on-site tank.

Using the same principles as a vacuum cleaner, the process manages the task of exposing everything from gas and optic fibre substructures to electricity cables – in fact just about all susceptible underground utilities.

It is environmentally friendly, affords reduced reinstatement costs and is suitable for both civil and major infrastructure projects - including the recent Sunbury Line Upgrade in Victoria, which will use non-destructive digging to locate and expose underground services and cables as part of newly announced establishment works.

What makes non-destructive digging different is not only the way it works but the almost total elimination of risk compared to mechanical excavation, jackhammering and drilling. It is also fast, safe and efficient.

Proudly Australian owned and operated, ExcaVac has set the standard for over a decade when it comes to NDD, and has a team of qualified professionals operating its own modern fleet of trucks and equipment.

Servicing Sydney Metro, The Blue Mountains, Southern Highlands, Illawarra and the South Coast, we have been a trusted name to industry, government and private enterprise since 2007.

Do it safely - every time

Tue, 07 Jul 2020 03:52:20 GMT

The safest method to expose or excavate

As one of NSW’s leading providers, Excavac has been at the forefront of maintenance services to industry, government agencies, manufacturing, construction, engineering, telecommunications and the mining sector for well over 25 years. With massive redevelopment and infrastructure projects now earmarked for NSW as part of the state’s re-emergence from COVID-19, it’s imperative that any excavation project is performed responsibly and reliably.

Non-destructive hydro excavation or vacuum excavator techniques are widely accepted as the safest method to expose or excavate.

In layman’s terms, the theory behind vacuum excavation is easy to grasp, with operating equipment penetrating hard soil with pressurised water to break up the solid earthworks into slurry. The loose soil is then vacuumed through a hose into a collection tank for later disposal, safely exposing the sub-surface without the risk of damage or injury to the operator, the environment or underground services.

Applications include:

Potholing of gas, water, sewer and telecommunication lines
Excavating around gas, water, sewer and telecommunication lines
Straightening of power poles
Tree planting and remediation

Benefits include:

Cost-effective, safe, quick and efficient
Minimises risk of damage to underground assets and tree roots
Significantly reduces potential safety risks
Has minimal environmental impact
Produces less waste

What lurks beneath?

Mon, 25 May 2020 05:12:08 GMT

Not sure what’s beneath your job site?

There are literally hundreds of thousands of kilometres of underground pipes and cables, which carry essential services to households and businesses around the Australia.

As easements and roadways become more congested with these utilities, it’s vital to visually identify their location — to ensure the safety of your workers and reduce any nasty (or costly) surprises.

Accidents and disruptions from builders and home owners unsuspectingly exposing underground assets cost millions of dollars each year and can significantly impact services, delay projects even cause death or injury.

This is where potholing using ‘sucker trucks’ with vacuum excavation comes into its own.

Potholing is a technique to expose a utility prior to excavation and allows contractors, engineer and builders to know exactly where the utility is located. This information can help avoid construction damage to the utility or to the people around the utility.

Vacuum excavators are self-contained units that use pressurised water to displace soil and create wet spoil.

The displaced spoil is removed from the area through a hose using high-velocity suction and stored in a holding tank.

Since vacuum excavators use water to remove spoil, they are perfect for potholing to identify existing utilities during underground construction projects.

While services such as Dial Before You Dig are useful, it is essential that property owners or construction managers thoroughly do their homework to discover what, if any, underground water pipes or utility lines might lie unseen below the surface on the property.

Our experience allows us to provide a clear understanding of underground utilities before manual excavation, preventing any workplace injuries and damage to significant assets.

Why is Potholing Important?

It helps avoid any disruptions to utility services
Promotes solid health and safety practice
Alleviates expensive repairs for damages

Potholing determines the exact location of these underground services.

It is a safe and effective method, which avoids damage and the associated expensive consequences.

The new face of infrastructure

Tue, 14 Apr 2020 06:28:18 GMT

Don’t risk excavation near sensitive utilities

The face of sustainable infrastructure development in Australia has changed dramatically over the past decade.

Non-destructive excavation (sometimes also known as non-destructive digging or NDD) is less invasive, more controlled and generally a safer and more effective form of excavation.

With the propensity of new works, limiting the amount of disruption to public movement is vital. Ensuring local economies continue to function is paramount.

As NSW braces itself for a massive infrastructure push, sustainability, safety and surety should really permeate every part of the process.

Old methods of construction and excavation need to make way for newer, tailored methods while processes such as non destructive digging and engineers are starting to work closer to make a difference.

Working smarter, more efficiently and more cost-effectively affords greater control over our impact on the environment, a reduction in disposal costs as well as transportation time and resources.

Industrial, commercial or domestic sites, roadways, public sites or direct drilling, remove your risk of hitting utility services and make the job safe, quick and easy.

Excavac has operated since 2007 providing the best value professional pot holing and non-destructive excavation services.

Don’t risk excavation near sensitive utilities before calling us. Let us eliminate the risks involved so you can concentrate on your project.

A waste of no-one’s time . . .

Mon, 09 Dec 2019 22:24:02 GMT

Disposal of waste can be risky

When it comes to environmental degradation failure to dispose of the waste properly carries not only a risk to the environment but to workers and the public.

It is the concentration of the substances discharged, and their total mass that creates an issue – and can often pose a health and safety risk – and can bring with it fines to operators.

High performance non-destructive equipment makes pit cleaning quick and easy. Hydro vacuum cleaning of electrical and communication pits is generally viewed as the only practical way of cleaning them properly.

Whether it’s public faculties, shopping centres, large industrial sites, rental properties or renovation works, programmed maintenance offers a simple solution to avoiding often complex problems later on.

Hydro vacuum cleaning is not only efficient, but cost effective and can be employed when it comes to;

Removing waste
Sewer, stormwater drain and pipe cleaning
Cleaning pits
Liquid removal
Tank and vessel cleaning
Emergency spill situations
Scheduled maintenance shut downs

Vacuum and pit clearing trucks are also used in the petroleum industry, for cleaning of storage tanks and spills, while they’re also virtually a mandatory requirement in today’s professional and social environment when it comes to removing drilling mud, drilling cuttings, cement, spills, and brine water from production tanks.

Sustainability and rethinking how we treat waste helps to preserve the environment for everyone by delivering efficient, safe and technologically responsible water, waste and energy solutions.

Complex challenges for builders

Tue, 12 Nov 2019 00:40:03 GMT

The risk is simply not worth it

With a complex network of over 22,000km of water mains stretched across Sydney (about two-thirds of these assets are buried) there are significant challenges for builders, construction companies and infrastructure developers.

Sydney Water spends up to $90 million a year on water main renewals alone, while the costs involved in repairs is also increasing.

When you also consider the Australian water industry owns and operates assets with a combined value of over $160 billion, with 220 urban water authorities supplying water to over 20 million people and employing over 31,000 people, the time, expense and inconvenience caused by using traditional heavy machinery when it comes to subterranean work can be substantial.

With over a dozen key infrastructure projects in metro and regional areas currently underway, including Sydney’s Rail Future, investment in the construction and civil sectors is virtually unprecedented.

A number of the technologies including non destructive excavation have now been adopted in a “business as usual” outlook by many in order to minimise the impact on the environment, and is widely regarded as the ‘go to’ method when it comes to both large scale & domestic projects.

Gas, water, sewerage, electricity and communications subsurface utilities pose a threat when it comes to all building and excavation work, and it is critical to efficiently locate relevant infrastructure before any work on site is commenced.

Today, the majority of utility providers require contractors to prove the existence and location of the utility, with some insisting the utility to be fully exposed before works start.

‘Dial Before You Dig’ recommends the use of non-destructive excavation as the best practice method to identify, locate and protect any subsurface utility.

Underground gas lines, communications and publicity owned utilities are usually a maze of cables and infrastructure that ‘in the main’ are poorly mapped.

The risk is simply not worth it.

Sometimes You Need to Dig Deep

Fri, 25 Oct 2019 02:06:22 GMT

Cost effective, minimal damage hydro excavation

While big business, mining companies and local councils are well versed in purposes of vacuum trucks, builders, developers and even members of the general public may not know of their potential value.

While ‘vac’ trucks have traditionally been employed to take on tasks such as emptying septic tanks and cleaning sewer pipes for proper preventive maintenance, one of the latest applications of vacuum trucks is hydro excavation.

Putting things simply, this involves high-pressure water jets doing the work of heavy machinery by excavating to subterranean levels before an industrial vacuum hose pulls the debris into the tanks.

The technology can (and has been used) in emergency situations, especially when spillage issues are involved.

Industrial vacuum trucks and trailer-mounted units are categorised into a range of debris tank-equipped machines.

Combination sewer cleaning, hydro excavation, and industrial vacuum units are all considered to be industrial vacuum trucks and are characterised by high-pressure water and powerful vacuum systems that are designed to take on the toughest jobs.

A growing trend throughout Australia is the use of industrial vacuum trucks on the construction site, where excavation trucks are ideal for precise excavation and underground utility daylighting.

Performing hydro excavation with these units – is more precise and cost-effective and does not cause damage to underground utilities, a common occurrence with traditional excavation equipment.

Other uses of this type of industrial vacuum truck in construction includes soil trenching, removal of debris, cold weather digging and piling hole excavation.

There’s no thrills in spills

Mon, 30 Sep 2019 06:59:46 GMT

We can clean-up just about any type of spill

Liquid waste spills that are not appropriately handled can harm the environment and your business.

In the event of any spill, the individual(s) who caused the spill is responsible for prompt and proper clean up.

Many of the basic steps involved in cleaning up emergency and non-emergency spills and leaks are similar.

As with all spills, know what you are dealing with, and only respond if you have been suitably trained, have the required materials on hand, and are wearing appropriate protective equipment.

You have a duty to notify pollution incidents to the Department of Environment and Conservation (DEC) on 131 555 or your local council.

Failure to report a pollution incident that has the potential to cause material harm to the environment is an offence. The maximum penalty is $250,000 for corporations, or $120,000 for individuals.

Businesses responsible for causing a pollution incident, and/or the owners of the liquid waste, are responsible for clean up and disposal costs in the event of a spill.

With a high-pressure wash-down and large capacity vacuum, our trucks take care of non-toxic spills quickly and cost effectively.

We’re a full-service, fully insured contractor, available 24/7 – capable of responding to just about any type of spill.

Remember:

Attend to liquid waste spills immediately.
If it is safe to do so, stop the spill at its source.
For spills of hazardous liquid waste, contact the NSW Fire Brigade immediately on ‘000’.
Log all incidences of spills.

Investigate the cause of each spill and ensure that precautionary action is implemented to lessen the risk of a similar incident recurring.

The ‘suck n truck’ method of waste removal

Fri, 30 Aug 2019 06:34:14 GMT

Sucker trucks are highly efficient

Well-equipped and versatile vacuum or ‘sucker‘ trucks are critical when it comes to on-site mud removal, spills and clean-ups.

The need to minimise on-site vehicle activity when the site is muddy, while restricting vehicle access to one stable entry and exit point is also now being increasingly scrutinised.

Sucker trucks are tank trucks that feature a heavy-duty vacuum system designed to use the technology to load liquids, sludge or slurry through suction lines.

Pneumatically sucking sludge, slurries, liquids etc. on-site into the tank of the truck, the material is then transported to another location for approved/safe disposal.

Sucker trucks can also be used for sewer pipe cleaning and septic emptying, clearing of storm drains, sewer lines and catch basins as well as just most projects requiring the removal of debris or liquids.

ExcaVac’s modern fleet of vac loading and vac excavation sucker trucks offer safe, efficient and cost effective removal of all wet and dry waste products including regulated and non-regulated spills of hazardous materials.

Our highly efficient units, hold between 4000 and 8000 litres of spoil and 3000 litres of fresh water each - plus we're Australian owned and operated.

Servicing Sydney, The Blue Mountains, Southern Highlands and the Illawarra, Excavac is a full-service, fully insured contractor, available 24/7.

Non Destructive Digging

Tue, 16 Jul 2019 23:01:18 GMT

Clean, Green and Efficient

Large-scale investment by the NSW Government in infrastructure, aligned with increasing concerns for safety & the environment, mean ‘old school’ methods of excavation are now making way for ‘new schools of thought’.

With 10 key infrastructure projects in metro and regional areas currently underway, including a $90 million investment into Sydney’s Rail Future, investment in the construction and civil sectors is virtually unprecedented.

To minimise the impact on the environment, non-destructive digging (NDD) is now the ‘go to’ method when it comes to both large scale & domestic projects.

Using high-pressure water and a vacuum to break up and remove earth (as a safer and more precise way of excavating) NDD also has the benefit of exposing utilities and underground pipes minimising the risk of damaging them.

Cost effective, time efficient and regarded as a safer alternative to traditional methods, it also creates less noise and dust pollution and helps eliminate workers’ exposure to possible environmental hazards.

Using precise, high-pressure water and an air vacuum, NDD cuts through the soil before an air vacuum is used to haul and transfer the soil to a debris tank mounted on a ‘sucker’ truck.

Mimicking the effect of mechanical digging, the targeted water pressure doesn’t impact the surrounding area, underground assets or tree roots.

Since hydro excavation (sucker) trucks can be positioned at a distance, problems connected with heavy machinery obstructing large areas can also minimised.

Now widely used within the plumbing, construction, landscaping & installation sectors, NDD is also suitable for use with straightening power poles and soil sample coring.

Hydro Excavation – Precise, Safe and Cost Effective

Quicker, eco-friendly and safe

As with any new construction project, it’s crucial to know which utility assets are buried underground. Whether you’re an engineer, contractor, stakeholder or homeowner, the cost and safety benefits of hydro excavation are even more apparent when you have a more comprehensive understanding of the risk associated with alternative methods.

According to the group CGA (Common Ground Alliance - a member-driven association of 1,700 individuals, organisations and sponsors within the underground utility industry) over the past 20 years in the US alone there have been 1,906 injuries and 421 deaths attributed to hitting underground utilities, almost entirely energy infrastructure.

They also site 316,442 cases of utilities being hit during excavation in 2017 at an average cost of $US4000 in direct costs per hit.

In Australia, underground utility conflicts and relocations are a major cause of project delays particularly during road construction.

Studies that have shown that the cost of detecting and safely navigating underground utilities prior to construction typically costs less than 0.5 per cent of the total project construction cost, and saves more than $4 for every $1 spent while reducing project delivery time by as much as 20 per cent.

More importantly the indirect cost, including traffic disruption, injuries to workers, and loss of business custom is just as telling.

Every construction project requires an investment in time and effort which today should include the use of vacuum and hydro excavation equipment in detecting and exposing underground infrastructure prior to (and during) excavation.

It’s been estimated that traditional construction tenders can be inflated by 10-30 per cent to accommodate the additional manpower required, risk perception and social disruption.

Hydro excavation is eco-friendly and safe that gets the job done quicker and more effectively with significantly less work required from manual labourers.

From cutting trenches for plumbing and pipes through to sewer systems pole maintenance, hi-tech installations commercial and industrial projects and landscaping, hydro excavation is precise, safe and efficiently cost effective.

Hydro Excavation - a better solution

Increased safety, efficiency and accuracy

For decades, traditional excavation methods used manually intensive – physically rich techniques, which not only posed dangers but were also time consuming and costly.

Today, hydro excavation is simply a better solution.

Employing a specialised process to remove soil using pressurised water, hydro excavation engages air vacuum systems to transfer the debris and soil to debris tanks. This allows a more accurate and non-destructive way of excavating soil and locating the underground utilities.

With high-pressure water cutting through the soil to break it up, industrial vacuums then lift the slurry from the excavation area. The process relies on two main components – high-pressure jets of water and a strong vacuum hose with soil and debris transferred to designated tanks.

Even in areas which have limited space, excavation work is now an efficient and safe operation, and unlike more traditional methods ExcaVac trucks can be used to exhume almost any type of material at a construction site including compressed clay, sand and gravel.

With increased safety benefits, time efficiencies and less manpower, there is also minimal to no damage to surrounding areas.
It provides a more accurate and precise job, helps to protect pipes, utilities and sub-structures and is environmental friendly.

Hydro excavation is also ideal when it comes to slot trenching reduces liability and insurance costs

Whether it’s a large commercial or construction job, landscaping contract or plumbing issues, hydro excavation is now the first choice when it comes to cost effective, industry standards.

Five Advantages of Hydro Excavation

The safer, technically superior alternative!

Industrial, commercial and residential excavation services have come a long way in 20 years. Gone are the days where skid steers, backhoes and bulldozers were your only options, now more economical and time efficient methods such as non-destructive hydro excavation are safer, technically superior alternatives.

Unlike traditional mechanical excavation, damage or disruption to critical underground utilities is avoided while typical excavation projects are performed in a fraction of the time compared to conventional digging methods.

Here’s just a few reasons why non-destructive hydro excavation works:

The process is more accurate and efficient
It maximises safety
There is a marked increase in efficiency and decrease in down time
Surrounding areas remain undamaged
Self-contained trucks transport removed materials, eliminating the need for additional costs and time associated with haul away equipment

Today, hydro excavation is considered to be a best practice by municipalities, contractors and public utility organisations alike.

Versatility, efficiency, safety, environmental sustainability and cost – just five reasons hydro excavation is breaking new ground.

Environmentally sound, technically superior, commercially efficient

It’s safe, clean, environmentally friendly and efficient

Underground gas lines, communications and publicly owned utilities are usually a maze of cables and infrastructure that ‘in the main’ are poorly mapped.

Traditional mechanical excavation methods are not only messy, labour and equipment intensive but can also seriously affect hidden substructures and harm the environment.

Today, non-destructive excavation (NDE or non destructive digging NDD) is a more precise method of operation, using either pressurised water (or air) to mobilise soil, along with an industrial strength vacuum to simultaneously excavate soil with minimal environmental impact.

It offers safer working conditions, is cost effective and eliminates many of the on site risks. NDD around utilities can be done in a fraction of the time compared with conventional methods.

Whether it be power, gas, water or telecommunication lines – hydro vacuum excavation allows for safe and efficient ‘excavation’ that mechanical equipment is simply not capable of achieving.

From potholing and excavation to safely planting trees in areas with valuable underground assets (even the straightening of power poles without the need for removal) – the advantages NDD technology brings, supersedes older more invasive and generally costly methods.

It’s safe, clean, environmentally friendly and efficient.

Plus, NDD has the ability to keep a pit dry of ground water for service technicians, trades and inspectors to ensure minimal disruption.

With approximately $50 billion government investment into infrastructure, the way we work is changing for the better.

NDD now plays a vital role in not only protecting infrastructure, but also the environment with reduced landfill, reduced transport and fuel costs, which benefit us at a local and global level.

Unfamiliar with the term Non Destructive Excavation? You’re not alone.

Non Destructive Excavation (or NDE) is an environmentally efficient means of excavating earth around buried utilities such as water mains, communication and power cabling, gas etc.

Also known as Hydro Excavation, Potholing and Asset Proving, NDE not only massively reduces the risk of damaging underground infrastructure before you excavate, but is also cost effective and non-intrusive ensuring significantly less environmental risks and impact to the immediate work site.

Used in conjunction with GPS mapping and hydro suction equipment, NDE technology has become increasingly popular with large-scale operators looking to reduce downtime and cost, while increasing site safety and productivity.

Ideal for excavation and installation of power and street lighting, exposure of utilities/services, removal of rail ballast and trench work, NDE is also suitable for

Excavation around tree roots
Trench excavation around or under obstacles
Conduit cleaning
Exposure of underground utilities prior to excavation

The process virtually eliminates labour-intensive hand digging and greatly reduces environmental impacts, with high-pressure water and vacuum tanks (or sucker trucks) being the key ingredients to removing sludge.

Not only is the process extremely efficient, but buried services can be clearly identified and marked to ensure the exact location of any possible issues when working on a site.

The ‘sucker trucks’ used in the process of NDE are also effective when it comes to cleaning electrical, communication, or stormwater pits to remove sludge and water borne debris an environmentally friendly means.

NDE is non-mechanical, fast, safe and less invasive than using heavy equipment, it limits congestion with few vehicles needed on site to get the job done, reduces labour costs and is better for the environment.
