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.
