18 years ago the Florida Department of Transportation contracted with us to line a culvert 30 inches in diameter x 75 feet in length. This culvert was at the base of the Destin Pass bridge in Destin, Florida. The FL DOT was concerned that infiltration would undermine the integrity of roadbed. See video below for an update 18 years later, (it’s doing just fine). Contact us about lining culverts for your municipality!
