Hydro Excavation is cutting-edge green technology that uses pressurized water to safely and surgically convert solid ground into loose soil that is quickly sucked up by a powerful truck-mounted vacuum system. The unique process of Hydro-Excavation allows for remote digging.
It is not necessary to make access for large excavating equipment and incur huge restoration and post job costs. Our Hydro-Excavators are equipped with rubber extension hoses that allow for the equipment to be positioned out of the way.
This means that only vacuum hoses and water guns are necessary at the dig site. Now, excavating in buildings, crawlspaces, or other confined spaces is a reality. 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. Where the material is dumped depends on the type of material. Generally, 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. Ninety-nine percent of the time, the plant will have its own dump site within the facility.
Air excavation has become a preferred method for digging on many jobs ranging from utility work to advanced tree care. Excavating with the AirSpade offers a number of advantages over conventional tools such as picks, shovels, and backhoes, including:
- Two to three times faster than hand excavation.
- Less worker fatigue than a pick or shovel.
- Eliminates sharp metal edges as featured on picks, digging blades, or buckets.
- Harmless to buried, solid objects such as utility lines, telecommunication cables, tree roots, hazardous waste containers, or military ordnance.
- Excavates some rocky soils where a shovel is difficult to use.
- Breaks soil into small particles that are ideal for re-compaction.
- Powered by common, tow-behind air compressors.
