Pipe Renewal - Model ASTMF-2561 -Pipe Rehabilitation Systems

F-2561 is a standard practice for the reconstruction sewer service lateral pipe and its connection to the main pipe without excavation. This is done by using a resin impregnated one-piece main and lateral cured-in-place (CIPP) lining that is installed into the sewer pipe by means of inversion. Once cured, the trenchless sewer line replacement consists of a continuous, one-piece, tight-fitting, corrosion-resistant pipe that extends over a predetermined length of the sewer lateral pipe and provided a structural sealed connection to mainline liner.
