The Benefits of NDD Excavation

Excavation is an important part of construction. It allows you to remove rocks and soil from the ground to establish the foundations for buildings. Locating underground utilities is part of laying the groundwork for a successful construction project. Unfortunately, it’s a process that can take quite a negative toll on the environment. Soil erosion from construction sites plays a major part in land degradation, with excavation disturbing the surface vegetation and generating waste.

Luckily, traditional forms of excavation are not your only option. Non-destructive digging is an environmentally friendly form of excavation that is also safer for your employees and better for your infrastructure.

Also known as hydro excavation, vacuum excavation or vacuum truck excavation, non-destructive digging is a form of excavation that uses pressurised water to break up soil and debris. Once the soil has broken up, it’s vacuumed and deposited offsite. Non-destructive digging is commonly used in urban areas with densely packed infrastructure for applications like potholing and trenching and a range of industries, including construction, excavating around water, gas and telecommunication lines, environmental remediation and digging for soil samples.

Traditional digging requires heavy equipment like excavators and backhoes to break down and move the soil. By contrast, NDD excavation is a non-invasive approach that’s effective in breaking up even heavy clay or rocky soil without being as damaging or destructive. According to the NSW Government Centre for Work Health and Safety, NDD digging is “a game-changing type of excavation that has transformed the construction industry”. With the right safety controls and procedures, non-destructive digging can even be performed on certain soils contaminated with asbestos.

As safety experts trusted by some of Australia’s largest construction companies, SSTC is happy to take you through the benefits of non-destructive digging, both for your staff and for the environment.

Worksite Benefits of NDD

NDD excavation is a safer option for employees, with less manual labour involved and the potential to operate the equipment remotely. Here are some other significant and vital benefits of NDD for your worksite:

NDD is safer for your staff

Non-destructive digging is widely considered the safest way to dig commercially. There’s a lot less manual handling to deal with, and sometimes, you can operate the equipment completely remotely, allowing your team to stay at a safe distance. Only one machine is typically required to suck up, store and remove the debris, which further reduces the risks of operating heavy equipment. On top of that, your chance of accidentally striking buried infrastructure is much lower, which further reduces the risk of accidents and injuries.

NDD is cost-effective

NDD digging is better for your budget for many reasons: fewer team members, fewer hours are needed to operate the machinery, and less time is needed to clean up afterwards. With fewer hours required onsite, it’s a fast and affordable approach that helps keep operational costs low.

NDD is better for densely populated areas

This one is beneficial for both your business operations and for the environment. In densely populated areas, the vibrations from excavation can cause structural damage to surrounding houses. Non-destructive digging significantly cuts down on the risk of this happening.

NDD reduces the risk of damaging infrastructure

Non-destructive digging has a much lower rate than traditional excavation of causing damage to underground wiring, pipes and other services. This makes the process of checking the infrastructure before you start a construction project much easier.

Environmental Benefits of NDD

These days, businesses need to show their commitment to sustainability and looking after the environment. By including sustainability in your business strategy, you protect your staff from safety risks and your brand from bad PR.  

NDD excavation is becoming increasingly popular for endeavours like trenchless pipeline projects. The combination of high-pressure water and an air vacuum allows for removing large quantities of earth without damaging the environment around it.

The biggest benefits of NDD digging for the environment include:

NDD is a fast and clean option

Other forms of excavation can be messy and can even interfere with underground infrastructure. NDD excavation, on the other hand, hones in on a specific spot. This targeted approach makes for a cleaner and faster solution. As a testament to how effective it is, all kinds of industries from communications to oil are adopting it to help them clean up their act.

NDD excavation can turn a job that would usually take hours into minutes, cutting down on the amount of time you need to spend digging up a particular area.

NDD is targeted

While traditional digging can interfere with tree roots, plants, rabbit warrens and other natural features, NDD digging affects a smaller and more precise area that leaves more of its surroundings untouched. This precise and intentional approach gets the job done while reducing the impact on the natural world.

Disruptions to soil are minimal

Excavation projects greatly affect the soil of an area, with more potential for collapse depending on the soil’s compaction strength. However, non-destructive digging dramatically cuts down on the amount of soil disruption and avoids interfering with the surrounding soil structure and root systems.  

NDD is quieter

It may sound like a small benefit, but it makes a big difference in residential or densely packed areas. Non-destructive digging is quieter, with the relatively low and brief noise of a single pump. Noise pollution is bad for wildlife habitats and human health, and fortunately, vacuum excavation can cut down on it.

NDD produces lower carbon emissions

Non-destructive digging is an energy-efficient approach that consumes less fuel and emits fewer greenhouse gases, making for an energy-efficient approach. By reducing the need for heavy machinery, this form of digging can lower the carbon footprint of your whole construction project.
