MOUNT AIRY, NC—Concrete Jack, Inc. of Williamsburg, VA, a company specializing in concrete leveling and foundation repair along the Eastern Seaboard and the South, used TerraThane Geotechnical Foam system to help save the parking lot of a Wake Forest, NC auto repair business.
"Parking lots are notorious for sinking from failed storm water structures," says Kirk Roberts, division manager for Concrete Jack. "Water causes erosion around the structures, voids form, voids enlarge over time then the parking lot just collapses. Sinkholes can shut down businesses and cause damage to customer vehicles."
Roberts says the municipality’s public works department determined the joints between the four foot sticks of pipe had been improperly gasketed, or seated, during installation. The pipe saw a continuous flow from a small stream entering at an end wall and discharging into a box culvert crossing a public street. The drop inlet at the downstream junction between the RCP culvert and box culvert also failed at the 18-inch RCP culvert feeding it, which had been repaired multiple times using open trench excavation.
