EMS provides hydro-excavation on certain sites as an alternative to conventional excavation methods. Unlike traditional mechanical excavation, there is little chance of damage or disruption to critical underground utilities when pressure washing and high-power vacuuming are utilized to excavate. Hydro-excavation allows EMS to penetrate various soil conditions, depths, widths and angles, while preserving natural surroundings. Hydro-excavation equipment is directed at the desired excavation point while the soil slurry is vacuumed into a vacuum truck to be contained and/or transported off-site. The entire excavation process requires minimal backfill, labor force, restoration and environmental impact.
