CIPP - Cured in Place Pipe Lining
CIPP is the most popular type of sewer repair system due to its low cost and trenchless installation. We can install a liner from manhole to manhole to restore its structural integrity, limit root intrusion, and restrict groundwater infiltration.
The process involves the inversion of a resin-impregnated felt liner into a damaged sewer. Hot water or pressurized steam is introduced into the liner to form-fit and cure the resin. Service laterals are then restored internally with robotically controlled cutters and cameras.
The CIPP liner is inverted into the existing sewer through an air inversion machine at the upstream manhole. The liner is stored in a refrigerated truck to keep the resin from hardening.
