Abstract: The method for lining a pipe laid in the ground, especially a sewer conduit made from concrete, asbestos cement or stoneware, comprises making a lining tube for the pipe with an outer layer and an inner layer made from fiber fleece and a barrier layer impermeable to fluid located between the inner layer and the outer layer. The outer layer is soaked with a stress-free hardenable plastic resin adhering well to the pipe in one or more regions of over its entire length and the inner layer is soaked with the same or another plastic resin having reduced shrinkage not impairing the outer layer. The lining tube is introduced into the pipe and pressed on the inner surfaces of the pipe to be sanitized. The plastic resin is hardened to form an adhesive bond between the pipe and the outer layer. Advantageously the outer layer is soaked with epoxy resin and the inner layer is soaked with polyester resin. The product of this method, a sanitized conduit, is also described.
