A high-pressure water lance is used to excavate and expose underground assets and open trenches, utilising a high-velocity vacuum organic and non-organic material is quickly removed with waste safely captured in the large debris tank.Request a quote
The risk of damage to utilities is significantly reduced using this method compared with other traditional manual or mechanical earthmoving techniques. Water pressures can be lowered or raised by operators to comply with the asset owners’ regulations.
Non Destructive Digging provides a safe, clean, and precise way to expose underground infrastructure, allowing for a much faster and more environmentally friendly method of excavation, with little risk to the environment, existing infrastructure can be exposed quickly and safely.
NDD eliminates the need for large, expensive excavators, saving both time and money compared with other manual or mechanical digging methods.
By eliminating mechanical tools, our Non-Destructive Digging method significantly reduces the risk of damage to utilities, ensuring the preservation of underground assets throughout the excavation process.
NDD allows for minimal surface disruption, reducing environmental impact. All spoil removed during exaction works is captured and disposed of at a registered waste facility.
Using water and suction rather than mechanical tools means the process is significantly quieter than traditional excavation methods, NDD is well suited to metropolitan and residential areas where noise pollution is a major consideration.
TDG are leaders in the field of Non- Destructive Digging / Hydro Excavation, with some of the most powerful units on the market. Our state-of-the-art equipment allows us to significantly reduce the time required to excavate trenches and expose underground assets.
With superior suction, large debris tank volumes and overhead booms we deliver efficiency without compromising on safety.
Our commitment to efficiency goes hand in hand with our dedication to environmental responsibility. By employing correct non-destructive digging techniques and utilising adjustable water pressures we can maximise efficiency onsite which directly translates to substantial cost savings through reduced excavation time, reduced disposal costs and reduction in required fills to reinstate trenches/potholes.
Upon completion, the soil that has been removed can be returned to the hole, reducing waste. Excess excavated soil is easily disposed of from the combination jet/hydrovac unit tank at approved disposal transfer stations.
With our efficient and low-risk approach, TDG Environmental uses non-destructive excavation for a range of applications, including:
TDG’s Hook-lift Separator Bins are custom-built for stormwater waste, non-destructive digging mud and sweeper waste and aid our customers with minimising waste disposal costs. They offer an innovative solution for when it is not feasible for waste to be continually carted to a waste facility. They can be stored on site and transported to a waste facility once full. These separator bins have custom built screens that allow for the separation of liquid from solid waste and as such, liquids can be removed from the waste prior to tipping. They have a purposely designed back door sleeve for ease of tipping for a variety of vehicles. Our Separator Bins have a holding volume of 15m3 which allows for multiple loads of waste to be consolidated in one device and transported in bulk to the waste facility.
We use Combination Jet/Vac Units which are custom imported and one of the most powerful trucks in Australia, providing 4,000L of water and the largest debris tank in the industry.
TDG’s comprehensive reporting system provides detailed reports with all relevant information on assets located.
Our locators hold all relevant accreditations with service providers to carry out the work and have the experience necessary to get it done right the first time.
