Non-Destructive Digging

Non-destructive digging, also referred to as hydro excavation, makes of use of high-pressure water and vacuums to safely excavate soil, particularly when found around underground utilities.

NDD uses high-pressure water to remove material such as soil, dirt and sand, exposing the desired underground utility, the material that has been dislodged is vacuumed which allows for easy waste removal and creates a clean work site. CSA regularly perform NDD around various pieces of critical infrastructure such as sewer lines, power cables, gas lines, telecommunication cables and more.

Examples of what it can be used for:

Hydro excavation can be used to pothole or expose underground utilities such as pipes and cables with minimal damage and disruption. It is widely recognised that non-destructive digging the safest method of excavation and is recommended for services such as planting, removing and remediating trees, excavating around underground utilities, potholing, excavation of trenches and power pole straightening.
