Potholing, also known as vacuum excavation, is a non-destructive digging method that safely exposes underground utilities without damaging them. This method involves the use of high-pressure water or air to loosen the soil, which is then vacuumed up into a debris tank. By utilising this technique, it minimises the risk of damage to utility lines and effectively eliminates the possibility of injuries to workers and the public.
The process of potholing is highly recommended for various types of projects ranging from small residential constructions to large industrial sites. It allows for a precise and accurate location of underground utilities such as gas pipes, water mains, electrical cables, and communication lines, thus reducing the likelihood of disruption or delays in construction work.
Additionally, the use of vacuum excavation is not only efficient but also environmentally sound as it eliminates risks of soil pollution. The approach minimises the amount of soil disturbance and allows the disturbed soil to be replaced with minimal impact on the surrounding environment.
