Hydro Excavation Services

On-site hydro excavation servicesHydro excavation, also called hydro vacuum excavation, is a non-mechanical method of digging that uses a high-pressure water jet to loosen soil, then employs a high-speed vacuum to remove the soil and debris from the hole. Our custom hydro excavation equipment was designed by and built for McVac Environmental Services and produces up to 7000 psi of directional pressure for better productivity when cutting through rough ground and hard clays.

Benefits of Hydro Excavation Services:

Hydro excavation is fast, efficient, and powerful, and is an excellent way of digging in areas of rough ground or hard clay, for larger excavation projects, and when you are trying to dig without damaging underground features such as electrical wire, water or sewer pipes, gas pipelines, or fiberoptic cables. Unlike digging with shovels, backhoes, or other heavy equipment, hydro excavation allows construction to take place in areas where equipment can’t reach, increases digging precision, and eliminates the risk of digging in hazardous or sensitive areas. Hydro excavation is also an excellent option for construction that must take place in the winter months, because it can use hot water to break through frozen ground. Hydro excavation is used in several applications and industries, including general construction, utility, electrical, telecommunications, chemical, and oil and gas.

Features of Our Custom Hydro Excavation Equipment:

  • Directional pressure up to 7000 psi
  • An on-board water storage tank
  • Low water usage (5 to 9 gpm) for less waste and disposal
  • Temperature-control for water from 0 to 180 degrees

Vacuum or Hydro Excavation?

The choice between hydro excavation and vacuum excavation depends on the specific requirements of the digging project. In general, hydro excavation is faster and more powerful, and is a good option for larger excavation projects or for digging in areas with rough ground or hard clay. Hydro excavation may also be a better option when the ground is frozen, because it can use hot water up to 180 degrees. In cases where backfill needs to remain dry in order to refill the hole, vacuum excavation is the better option. With hydro excavation, a high-speed vacuum removes the wet, muddy soil from the hole, but that soil must be transported to a dump site for disposal—it usually can’t be used to refill the hole.
