A2TM Liner Pipe is a 46 psi PVC pipe with a smooth interior (Mannings “n” = .009), and flush gasketed bells. It was easily pushed through the existing culverts, up to 400 feet long, and then grouted into place.

There was no disruption of traffic, and no excavation and repair of pavement. Because of A2 Liner Pipe’s smooth interior wall, there was no loss of hydraulic capacity. Contech A2 Liner Pipe uses proven trenchless installation methods to slipline existing sewer lines without the disruptions associated with open trenching, while also increasing productivity and lowering costs.
