Project Description

NDD – Non Destructive Digging Unit

Non Destructive Digging (NDD), also known as vacuum excavation and hydro excavation, is digging up the ground using high pressure water in conjunction with vacuuming of the mud slurry generated. This method of digging is essential for jobs where the locating of underground services (electricity, water, telephone etc.) is unknown and electrocution or other dangers exist. Because only water and vacuum is used, the possibility of damaging existing services is removed making potential dangerous jobs safe.
