Hydro Excavation (also known as vacuum excavation, vac truck excavation or suction truck) is our speciality. It’s a form of non-destructive digging that uses high pressurised water and an industrial-strength vacuum to simultaneously excavate and evacuate soil
Becoming increasingly popular, Hydro Excavation and VAC Truck Excavation use this technique to safely excavate in situations where normal excavation machinery cannot be used. This non-destructive form of digging can remove almost any kind of surface without damaging existing infrastructures. For example telecommunications, fibre optics, Telstra cables and underground power lines, as well as around and under concrete and driveways. The possibilities are endless. With hydro excavation & vacuum excavation, all project managers can enjoy peace of mind knowing that the safety of everyone on site is being looked after during any excavation process. Eliminate accidents and workplace injuries with this cutting-edge method of excavation and digging.
The vacuum truck is a self contained unit which uses high pressure water at approx. 2,000 - 4000 psi (gerny) to break down the soil, while a vacuum pump removes the soil into holding tank on the truck. This ensures little to no mess. All Dynamic Hydro Excavation VAC trucks carry up to 1m3 of sand for back filling purposes if required. EXAMPLES OF COMMON USE:
