Hydro-Excavation is a non-mechanical and non-destructive process which combines pressurized water and a high flow of moving air to simultaneously excavate and evacuate native soils at a controlled rate. The soil and water slurry are conveyed via an 8" tube to a truck - mounted debris tank. This process allows for quick, clean and precise evacuations which require less backfill, less labor force, less restoration and less environmental impact than conventional digging methods. A controlled flow water stream allows for surgeon - like accuracy. While removing only material necessary for repair or inspection, minimal material needs to be removed when compared with the large, less than accurate excavator or back hoe bucket.
