Cured-in-Place Pipe Lining is also an economical form of pipe repair. The costs of treating the infiltration of groundwater that enters cracks, joints and other defects in the sewer system can add up quickly. CIPP can also help increase the flow and make the pipe more structurally sound. In many cases, CIPP is also more cost-effective than excavating and repair using traditional methods of pipe repair. Trenchless spot repairs are also a very effective method of repair, this technology is placed into the pipe and inflated with air, steam, or water and within minutes the resin has hardened to create a customized smooth pipe liner.
