In hydro excavation, debris and sediment soil are removed by using pressurized water instead of mechanical tools. The hydro-vac mechanic can suck out the thick viscous dirt to reach a deeper layer below the ground. This method clears the earth and dirt covering the pipe system with minimal risk of damage. After the excavation, a vacuum or air conveyance is deployed to transfer the soil or debris to a soil tank. This is a non-destructive to unearth soil to detect subversive utility systems. Hydrovac excavation services are extensively used in the oil and gas industry as they are more effectual than other daylighting procedures. When underground pipes are exposed to sunlight using a hydro-vac excavator, the process is termed day lighting.

Highly flexible

This excavation process is more effective in cold weather where the soil is icy; other methods of excavation are difficult to execute. High-pressure water is sprayed through a nozzle on the soil to soften it. Next, the mud sludge is transferred into the tank of the excavation vehicle. At this point, the crew can detect any underground facility system. Once the restoration job is completed, the slurry can be pumped out of the tank to cover the excavated area. Hydrovac excavation is highly flexible. The machine can be utilized for full excavation projects for daylighting digging out small areas to detect underground pipelines. Two types of vacuums can be deployed in a project: positive displacement blower and fan system. The latter one is easy to use, lighter, and more economically apt for fast excavation. At the same time, a positive displacement blower can reach deeper layers of the earth, which is ideal for heavy-duty excavation ventures.

Minimal infrastructural damage

The Hydrovac excavation system consists of high-pressure water and air vacuums. First, it softens and penetrates through the soil; next, the vacuum hages up the sludge from the excavation area. Using a hydro-vac system is more effective and safe than the conventional method, as mechanical tools can damage fiber optic cables, sewerage lines, and power and telecommunication lines. There are more chances of damage to these underground facilities during the conventional excavation process. When the cables are smashed, the service is disrupted for long. During the hydro-vac, the buried utility lines are easily visually detected. This averts damage to the crew, society and the laid infrastructure. As the chance of damage to the underground infrastructure is minimal, it is both cost and time-effective.

Precision

In hydro-vac excavation exact place is excavated without disturbing the surrounding soil, and the adjacent area remains intact while the necessary job is completed. The system is compatible with all kinds of soil, even in frozen soil where other digging processes are ineffective. Hydrovac equipment is designed to handle construction and utility projects. This method removes soil from the explicit area, whereas this precision cannot be executed in another excavation process. It is perfect for digging narrow trenches for laying or restoring cables. It is also an ideal solution for whole piling where poles, piles or other cylindrical structures are installed. This sort of excavation requires a high level of meticulousness, predominantly for small-diameter piles. The efficacy and advantages of hydrovac excavation services not only depend on the crew and the method used but heavily on the quality of equipment used and actual trucks.
