Gastonia, NC — City saves money with Snap-Tite
North Carolina City Saves Money by Relining Culvert with Snap-Tite® Pipe
Two corrugated metal pipe (CMP) culverts located in a residential neighborhood in the city of Gastonia, North Carolina were damaged due to rust. One culvert was 24 inches in diameter and the other one was originally 18 inches in diameter but had deflected inward reducing the interior dimension to approximately 16 inches, eight to 10 feet from the inlet end. This deflection was not discovered until the repair of the culvert took place. The city of Gastonia needed to replace the old CMPs but did not want to disturb the asphalt paved road. In addition, there were four underground utilities crossing that had the potential to be damaged if a traditional open cut replacement was used. A trenchless method of repairing the culverts was the better option.
City of Gastonia’s Public Works Engineer Jimmy Lineman spoke with Snap-Tite® representative Bruce Larson about the benefits of using the SnapTite® culvert pipe lining system. Snap-Tite® is made of high-density polyethylene (HDPE) pipe. It has a patented male/female machining at each end of the HDPE pipe that is ‘snapped’ together, piece-by-piece, and pushed into the full length of an existing pipe. Any annular space and voids between the old culvert and new liner are filled in with grout. The pipe liner is available in lengths from two feet to 50 feet, and is available for culverts with diameters from eight inches to 84 inches. Snap-Tite® also meets American Association of State Highway and Transportation Officials (AASHTO) Standard M326 for rehabilitating culverts.
