Trenchless Pipe Repair - The main alternative to traditional sewer replacement involving trenching is cured-in-place lining, sometimes referred to as 'soft lining' or 'cured-in-place-pipe' (CIPP), which has dominated the non-man-entry sewer renovation market in many countries for over twenty years.

Trenchless Pipe Repair makes use of a fabric tube impregnated with polyester or epoxy resin. The tube is inserted and pulled into the existing pipeline and inflated against the pipe wall, then cured either at ambient temperature or by re-circulating hot water or steam.

CIPP systems create a close-fit 'pipe-within-a-pipe' which has quantifiable structural strength and
can be designed to suit various loading conditions. The ring-stiffness of the liner is enhanced by the restraint provided by the host pipe and the surrounding ground, but systems designed for gravity pipelines do not rely on a bond between the liner and the substrate. Systems which rely on the host pipe for some measure of structural support are sometimes known as 'interactive lining' techniques.
