Understanding Daylighting

Daylighting refers to the process of uncovering and exposing underground utilities safely and efficiently. At Precision Daylighting Inc., we utilize a non-destructive excavation method known as hydro-excavation, or "soft digging."
Our hydrovac services combine high-pressure water with a powerful vacuum system to excavate, pothole, and precisely expose buried utilities. Water is delivered through a handheld wand to loosen soil, which is simultaneously removed by the vacuum and stored in an on-board debris tank. For frozen ground applications, our hydrovac trucks are equipped with on-board boilers to heat the water, allowing us to maintain the same efficiency and precision year-round.
Unlike mechanical excavators, which pose a risk of damaging underground infrastructure, hydro-excavation is designed to protect utilities while working more safely and efficiently in congested or sensitive areas.
