Quick Culvert Rehab
Government departments across the nation continue to address failing culverts that pose serious risks to state and interstate highways and city streets.
Unfortunately, once installed, culverts often are out of sight and out of mind. However, the result of neglecting this component of infrastructure eventually makes itself known, often in a catastrophic failure resulting in costly emergency repairs.
Indiana Reline Inc., Sulphur Springs, IN, is actively involved in rehabilitating culverts and other types of pipelines throughout the United States, using various technologies, depending on the level of deterioration and site conditions.
A recent project was to reline twin culverts for the Ohio Department of Transportation (ODOT) on U.S. Highway 23 in the northwestern part of the state. Indiana Reline was the general contractor performing erosion control, dewatering, constructing coffer dams, cleaning of the host pipes and site restoration. Abel Recon, Mountville, PA, applied the polyurethane lining.
Each multi-plate culvert was 90-feet long with dimensions of 13.5 feet by 8.5 feet, said Karl Bates III, Indiana Reline chief estimator/division manager. The age of the culverts is not known, but Bates said ODOT estimated they were put in place in the 1960s or early ’70s.
Identifying a solution
“Both culverts were structurally sound, but were experiencing signs of deterioration on the inverts,” Bates said. “Because of their condition, it was determined a spray liner was the best option to prevent further deterioration. Square footage inside the culverts was 6,789 square feet, and that was the basis for the cost of the spray and its application.”
Sprayroq Sprayshield Green II was selected as the material of choice for the project -- it is the first time the product was used by ODOT.
Sprayshield Green II is a semi-rigid, 100 percent solids polyurethane coating formulated for use in water, storm water and wastewater environments. It provides corrosion and chemical resistance for concrete, steel, masonry, fiberglass and other surfaces in municipal, industrial, agricultural and maritime applications. A 300 mil application was installed in each of the culverts.
