Hydro Excavating and Maintenance
What is Hydro Excavation?
Hydro- Excavation is the science of digging with water. Our self-contained trucks dig with 2000-3000 PSI water, forced through a steel lance and small stationary or rotating nozzles. We then vacuum the resulting water and soil slurry through an eight inch vacuum line into a debris tank to be dumped at the end of the day. The entire process is safe, fast and extremely cost-efficient, especially when digging around pipelines, sensitive fiber optic cables, or the plethora of other underground utilities.
Collection of Material
Hydro excavation spoils collect in a closed-container body also mounted on the truck. Once the tank becomes full, the vacuum system shuts off. The spoils are then dumped out like a dump truck.
Disposal of Material
Where the material is dumped depends on the type of material. Typically, hydro excavation is just dirt and water, so the spoils are taken to a dirt landfill where it dries out over a couple of days and is often used as backfill material. However, if the material is “hot” (possibly contaminated), it cannot be taken to a regular dirt landfill. Hot material is typically collected from hydro excavation sites in an oil, gas or chemical plant. Most of the time, the plant will have its own dumpsite within the facility. Our excavations are clean, precise and ready for inspecting or whatever further work is required, and our operators are thoroughly safety-trained. We uncover pipeline, phone lines, fiber optics – and anything else buried up to 30 feet underground quickly, safely, and without damaging any expensive or hazardous lines. We do pot holing, slot trenching or whatever non-destructive excavation services are needed, even swimming pools!
