Hydro excavation also known as water jet excavation uses pressurized water to remove soil. The loosened material is then transferred into a tanker for removal. This process is much more efficient than digging out these materials with a digger and requires less man power. Hydro excavation is great for removing soil from around sewer pipes and pipelines without causing any damage. This hydro excavation nozzle is designed with four forward facing jets for maximum impact and is made from stainless steel. A high quality nozzle manufactured by RM Suttner.
