Hydro Excavation


Hydro Excavation – What Is It?


Hydro Excavation is a process which combines non-destructive and non-mechanical pressurize water and a high-powered vacuum the excavate soil in a controlled manner. This process of excavation safely crushes up the soil, and the water and soil slurry is then transferred by vacuum to a debris tank. The conveying is done through an eight inch long tube that is mounted to the truck. The process of excavation provides a method of removing waste without unnecessary force and waste. Hydro excavation allows for water to break up soil instead of using mechanical or manual digging, eliminating the potential risk for damaging underground utilities. The hydro excavation process provides a higher safety, and a more precise method of excavations which saves on labor, restoration, backfill, and a less detrimental impact on the environment than that of tradition excavation.

Hydro excavation allows for inspection, repairs, and other necessary accesses where control measures are necessary for a much easier process. A significant benefit of hydro excavation services is that they can be utilized in virtually any location because the digging equipment and the storage tank are both attached to the truck. Rigs also have heating units which accommodate for cold weather digging. The most optimal locations for hydro excavation is cold weather regions.

The filtration system requires minimal upkeep, saving money on maintenance and equipment. Operations require a minimum of two people to maintain the truck and operation the excavation. Multiple locations can be visited and the debris stored in the truck for later disposal. The manual labor and equipment that is associated with regular excavation operations is extensive, the safer and more cost efficient method is to utilize the hydro excavation method to accomplishing the same desired outcome.


Cold Weather Digging


Cold weather digging is a method that typically creates a lot of pollution. Hydro excavation provide a safe and quick alternative to the pollution and allows a successful method for digging in cold weather conditions. As discussed earlier, hydro excavation’s main cutting agent is water. This is a non-pollutant method for digging in cold weather. It does not pose a danger to damaging vital infrastructures like sewer and water lines, pipes or communication networks. The process used with hydro excavation does not contaminate underground water, cause pollution, or pose a risk to the vital infrastructures.

There is also concern with moving debris from cold weather digging. The hard ground requires methods to be devised for softening and the conditions dangerous in traditional excavation practices. Hydro excavation has the warming equipment on the truck and uses hot water and steam to thaw the frozen ground. It also cuts trenches with far more precision than traditional excavation and weather does not affect this process. Hydro excavation’s process is highly tailored for the cold and able to provide a non-destructive, non-polluting, and accurate technology for any environment. The removal of the debris in cold weather poses no threat to the environment because the water and soil slurry is conveyed directly to the truck.

Cold weather hydro excavation requires only two crew members for a successful dig. Traditional excavation is labor intensive, even more so in cold weather digging. Wood, coal, or other elements are utilized to soften the ground before they can dig. Hydro excavation trucks have heaters for the water and the ground allowing excavation through the frozen ground.

Other important considerations in cold conditions include working to insure that pipes are better insulated by digging deeper in cold climates, and creating trenches are safe and firm for the crew in all weather conditions.
