NDD, also known as hydro excavation, uses highly pressurised water and air to blast soil or other surfaces. Because the water or air is concentrated on the target, it has no affect on the surrounding environment, subsurface assets, or tree roots, and it resembles the effect of mechanical digging. After the dirt has been loosened, it is pulled into the hydro vac storage tank together with other trash using a high-volume suction line.

The initial soil that was removed can be returned to the hole after repairs or construction is completed, reducing waste.

Vacuum excavation removes organic or inorganic materials, ranging from small particles to heavy debris, from existing holes or surfaces. Non-destructive excavation is the safest and most effective approach to expose and excavate around existing subsurface services, from pipe replacements and utility installations to the removal of street waste and demolition material. While both vacuum and hydro excavation work in the same way, excavation hydro equipment uses a water jet to break up material before sucking it up.

When excavating near underground services such as sewerage pipelines, gas, water, and communications lines, NDD is a fantastic solution. Mechanical drilling is slow because it poses a considerable risk to the environment, whereas NDD is both safe and efficient.

Non-destructive digging is a safe way for places with valuable underground assets, straightening electricity poles, and gathering soil samples with coring, in addition to potholing and excavation (while reducing risk of cross-contamination).
