Cured-In-Place Pipe (CIPP) lining
Cured-In-Place Pipe (CIPP) lining represents the pinnacle of trenchless rehabilitation technology, utilizing advanced thermosetting resins and fiber-reinforced materials to create structurally independent pipe systems within existing infrastructure.
Our CIPP installation process employs precision-engineered felt liners impregnated with vinyl ester or epoxy resins, designed to withstand extreme temperature variations (up to 50°C ambient). The process begins with comprehensive robotic cleaning using 4000 PSI water jetting, followed by detailed condition assessment using pan-tilt-zoom cameras with laser profiling. Liner installation utilizes either steam curing (105°C) or UV LED curing systems, creating a monolithic structure with tensile strength exceeding 55 MPa. Our specialized formulations account for high groundwater salinity and aggressive soil conditions.
