Daylighting or potholing refers to the practice of digging a test hole to locate underground utilities for tie-ins, or for repairs on gas lines, electrical conduit, water and sewer lines. Spruce City Sanitary Services Ltd. uses a unique combination of water pressure and vacuum, combined in one self-contained mobile unit. This method is the most preferred way to prevent damage and safely locate utilities underground as it is a non-mechanical, non-destructive process. This method saves time and cost when you want to dig holes for signs, poles and fences installation.
As hydro excavation creates the least amount of ground disturbance, it is preferred for environmentally sensitive areas. The process is simple. The water is pressurized and injected into the ground via a handheld wand to safely wash soil from the area and the resulting slurry is vacuumed from the excavation through a large debris hose connected to the units debris tank. We are equipped to handle large volumes of debris and water. We easily handle the removal of solid, liquid or dry materials (sand, dirt, slurries, sawdust, gravel, coal, fly ash etc.).
All underground strikes are costly. Some utilities are hard to locate, so when in question, it is always safer to use a hydro excavation in place of mechanical digging! Gas line, telecom, power line, sophisticated construction, water main or sewer main, no matter what you want to locate, our top-of-the-line equipment can get your work done faster and safer. If underground utilities are within 3 meters of the pole or anchor for hydro pole replacement and pole anchor installations, a hydro vacuum excavation is required. We can also help with monitoring utilities and installation of vapor wells, street light bases, sign posts and pilings.
