Method of softlining sewer rehabilitation

摘要

The present invention provides a novel method for softlining rehabilitation of pipe conduits in which the lining hose comprises an inner layer of resin-absorbing material and an outer layer which is a disintegrable coating. The outer layer initially allows for soaking the resin-absorbing material with resin, but disintegrates during installation so that the resin can contact the interior surface of the pipe conduit and provide an improved rehabilitation method. The present invention further provides a novel lining hose for use in softlining rehabilitation.
