Sewer renovation
CIPP (cured-in-place pipe) is a technique in which an existing pipeline is fully renovated by pulling a liner through the old pipe. This liner is then inflated under air pressure against the wall of the existing sewer, after which a UV light train passes through the liner to cure it in a controlled manner through exposure to UV light.
This technique can be applied both horizontally and vertically. Moreover, it is a trenchless sewer rehabilitation technique, making it an ideal solution to avoid extensive excavation and demolition works.
