Trenchless renovation of pipes
Trenchless renovation, with an inliner or partial repair, allows for fast, inexpensive and sustainable renovation of pipes and pipe joints. Excavation or demolition work where the floor and or walls are broken up in order to expose the defective pipes are not necessary. This saves not only time but also money.
Instead, a tube impregnated with special resin made of robust fabric (the so-called liner) is pushed into the pipe through a shaft. For a partial repair, it is often sufficient to wrap a piece of fiberglass mat impregnated with resin around a so-called packer and then push it into the pipe at the site of the defect.
Under pressure, the liner or patch is pressed against the pipe wall from the inside and cures there.
After a few hours, the sewer pipe is permanently sealed again and the sewer rehabilitation is complete after proper testing.
