Hi, We recently used Centracon hydrovac excavation services for a project in exactly this area, where there were a lot of utilities running underground, from water pipes to electrical cables. Traditional excavation methods would have been too risky and could have caused damage and delays. Hydrovac technology really does minimise the risk of damage, as the excavation is done very carefully, using pressurised water and a vacuum, allowing for precise control and avoiding contact with utilities. In addition, the work itself is completed much faster than mechanical excavators, meaning less downtime, quick removal of the soil, and, as a result, saving time and money.
