Vacuum excavation decreases operational risk due to its nondestructive nature and is safer than traditional excavation methods. Black Hydrovac is your go-to resource for your vacuum excavation needs. We offer air and hydro excavation, daylighting, potholing, debris removal, trenching and storm water management services. We can help you dig safer.
Vacuum excavation is an excavation method using high pressure air and/or water to break up dirt and a vacuum to remove the soil. This nondestructive method of excavation is cleaner and faster than traditional excavation. Vacuum excavation is also safer than traditional excavation, both for anything existing underground and for the hydrovac operators. This precise method of excavation also has minimal environmental impact.
Hydro excavation and air excavation are two types of vacuum excavation.
Daylighting - tEST pITTING
Daylighting for utility location is the most common use of vacuum excavation; test pits are dug to verify the depth and location of existing underground utilities. Daylighting to locate utilities reduces the risk of damage or injury caused by striking an underground utility while excavating or hand digging. Dirt that is displaced during daylighting can be used as backfill or removed. Either type of vacuum excavation (hydro or air) can be used for daylighting.
Potholing using vacuum excavation is a nondestructive method of digging holes for many purposes. There is minimal amount of disturbance to the environment and very low risk of damaging existing structures in the ground.
Potholing with vacuum excavation reduces the risk of utility damage caused by striking an underground utility while digging.
Potholing can be utilized for:
Utility location / daylighting
Utility pole installation
Fence post installation
Debris removal is safer and more efficient with our powerful vacuum trucks, and can be accomplished by utilizing either type of vacuum excavation (hydro or air). Vacuum excavation offers a cleaner and faster way to remove debris over the traditional methods utilizing a shovel and manual labor.
Common debris removal jobs include:
Removing filter media
Cooling tower cleanouts
Vacuum excavation allows operators to cut very precise slot trenches that are narrow and deep. This method of trenching offers minimal disruption to environment, allows for work in tighter spaces, and reduces backfilling issues. Trenching with vacuum excavation is the safest digging method when underground infrastructure is present.
Slot trenching can be utilized for:
Underground utility line installation and/or repair
Smaller pipe installation
Work around existing utilities
Storm water management
Storm sewers and pipes often get filled with sediment and need to be cleared out. Jetting is a process that utilizes a pressurized water hose with a jetting nozzle to push high-pressure water through the pipe and loosen and displace sediment.
Jetting and vacuum excavation can be utilized individually or simultaneously for managing storm water needs within:
