Non-destructive digging (NDD) offers a major advantage in that it greatly reduces the chance of damaging underground utilities. This, in turn, reduces the risk of costly delays and additional expense for construction companies.
NDD makes use of a pump mounted on a vacuum truck to generate powerful suction and remove earth and debris from an excavation. The wide-mouthed intake nozzle is held by one or more operators and is used to vacuum away material that has been loosened by a powerful water jet or compressed air.
Pressure Works provides vacuum excavation to Melbourne construction companies, contractors, and government departments.
Since non-destructive digging uses a suction excavator, it is also called “vacuum excavation”, or “hydro excavation” if a water jet is used.
Vacuum excavation (also known as suction excavation) is considered a best practice for safely locating underground utilities, reducing the chance of damaging underground assets by more than half.
