Daylighting is the process of exposing underground utilities or pipelines in order to repair or to add something beside the utility. The daylighting, or otherwise known as potholing, is done with the help of hydro excavation, which is a more efficient, safer and better alternative to hand digging. Hydro vac excavation is the primary means of daylighting. This is when the contractor uses extreme water pressure to break up earth while simultaneously removing the debris with the help of a powerful vacuum. You can imagine that this would be a lot safer, cleaner and more efficient way of daylighting. Employees are thoroughly trained in how to use these powerful machines to ensure a safe excavation.
