Our Slot Trenching Service
Slot trenching is one of the most common purposes of hydro and air excavation. Pressurized water or air cut thin, accurate trenches of various dimensions usually 6 to 24 inches wide and up to 8 feet deep. It’s an effective method when searching for utility lines especially when the location is unknown. Ecotech also uses slot trenching for installing pipes, sprinkler systems, cables, signs, posts and other utilities underground, and for narrow trenching around the perimeter of a foundation for the installation of grounding wires or electrical lines. With vacuum excavation slot trenches require a minimal amount of backfilling leaving established landscaped areas clean and requiring far less restoration than other methods.
