Slot Trenching in Mercer Island, WA

Narrow, precision trenches for utility installation with minimal surface disruption. Mercer Island, Washington's construction sector relies on slot trenching for safe, code-compliant work around the area's 25,042-resident metro and dense underground utility footprint.

What is Slot Trenching?

Slot trenching cuts narrow, controlled trenches — typically 6 to 12 inches wide — using pressurized water and vacuum extraction. The result is a clean trench suitable for installing fiber, conduit, water lines, or low-voltage cable in environments where minimal landscape, paving, or hardscape disturbance is critical.
