Track Rehabilitation / Inliner

The trenchless inliner method enables fast and comparatively inexpensive sewer rehabilitation. Particularly in the case of long pipe sections, it quickly becomes apparent that the effort and costs involved in inliner rehabilitation remain within reasonable limits. This is because instead of tearing up the floor and walls, a tube made of robust fabric material (the so-called liner) is impregnated with special resin and then inserted into the pipe. Using water or air pressure, the hose is pressed against the pipe wall from the inside and hardens there. After the curing time, the sewer pipe is permanently sealed again and the sewer rehabilitation is completed after appropriate testing.

If direct bonding to the old pipe is not desired, we recommend the use of a preliner. A preliner is a flexible film tube that is inserted between the liner and the old pipe. The preliner also protects the textile liner from water penetration.
