Loy Clark provides the most reliable method of underground utility line location and spot maintenance from our Vacuum Excavation Divison. This method uses minimum pavement removal and creates the least environmental impact. Vacuum excavation also reduces the extent of damage claims associated with traditional excavation methods. Cost savings on saw cutting, import material, dump fees, restoration and paving make this a valuable asset to any project.

Applications:

• Preferred alternative for utility service line location, idententification, protection, maintenance and repair.
• Expose existing utilities for engineering design of line and grade for proposed utilities.
• Cleaning of above and below ground vaults, catch basins, manholes and valve boxes.
• Directional drill support for mud removal and utility mapping.
• Facilitate cathodic protection for new installations, testing and renewal of previously installed anodes.

Features:

• Provides the most reliable method of underground utility verification.
• Affords access to underground utilities through small 10" openings in the surface.
• Typical working depths of up to 10 feet or more.
• Remote operation (up to 100 feet) of difficult access.
• Storage of up to 1,000 gallons of bentonite mud slurry.
• Hydraulic dumping for quick and easy emptying of a large 5 cubic yard (1000 gallon) tank.

Benefits:

• Cost savings on restoration
• Minimum pavement removal
• Minimum environmental impact
• Reduced damage claims
• Fewer injuries—no hand digging
