Hydrovac Excavation? How it works:
Hydrovac Excavation (or Vacuum excavation) is a process where pressurized water or air, is used to loosen and break up the soil or other material. Once the material is loosened, the vacuum and airflow, removes material from the excavation and stores it in a debris tank. The material is contained in the debris tank where it can then be transported offsite for disposal once the work is complete. Because vacuum excavation is non-mechanical, the potential to damage an underground utility such as gas lines, fiber optics, or electrical lines is significantly reduced.
- Safer than conventional methods avoiding costly delays related to damaged underground infrastructure.
- Burner/Boiler allows us to utilize hot water for excavation in frost and frozen ground down to -37°C.
- Effective with dry soil, wet soil, clay, gravel, crushed rock, sand and any other earth materials that conventional digging methods are used for regardless of weight or density.
- We can excavate from distances up to 900ft away from the truck unit when there are truck access issues, during those tough muddy seasons or even to prevent any damages to your property.
Daylighting is a non-mechanical source to excavate. It is pressurized water or air, which is used to loosen and break up the soil. Once the soil is loosened, the second non-mechanical source, vacuum and airflow, removes material from the excavation and stores it in a debris body.
Trenching projects are generally taken up for laying or altering cables or pipelines below the surface of the ground. When these activities take place within the confines of a city, it causes immense inconveniences to the public. For this reason, a quick and time-efficient excavation is preferred. Hydrovac excavation, with its superior small excavation equipment, is faster than its counterpart- mechanical excavation (which uses the traditional metal claws) and causes less inconvenience to the nearby residents.
There is a reason why experts prefer hydro excavation for small trenching projects. Hydrovac excavation allows greater directional control. This means an activity such as trenching which needs precise execution would benefit from the superior level of control small excavation equipment can provide.
Air excavation is the process by which high pressure air is used to loosen up the dirt material. This material is then vacuumed up into a truck and can be disposed of either on site or a designated disposal site. This advantage to this is give the client the capability to leave the materials on site since so they can be reused for backfill. It also saves significant travel time if water and the disposal locations are off site.
Municipalities and industries are mandating the use of hydro excavation over conventional digging when it comes to removing contaminated soil. Our fleet of hydro excavation trucks are equipped with the latest technology and highly trained staff to ensure that all contaminated soil projects are completed safely, on time and on budget 24/7.
Sometimes described as pump stations, wet wells are generally holding tanks used in gravity-flow systems. They come in a variety of sizes but are equipped with pumps that help remove sewage or other material to an outlet point for treatment. Because solids (rags, storm flush, oils, grit, silt, etc.) often obstruct or damage the pump, frequent inspection and cleaning is required to keep them running properly.
Cleaning and regular maintenance of catch basins is essential to ensuring that our streets remain adequately drained of excess water during heavy rain fall and melts/
It is important to first inspect of the cover or grate. Debris removal, including all buildup of material in the catch basin’s sump is then completed followed by cleaning of the walls and removal of all water and debris from the basin.
Pole Hole excavation is hydro excavating to illuminate critical pathways for the installation of various-sized poles. Hydrovac excavation is the recommended method of digging pole holes in residential and commercial zones where the presence of underground utilities is greatly increased and larger equipment cannot access those pole hole locations.
