The Technology
Understanding the science behind trenchless pipe rehabilitation.
Inspection & Cleaning
Before any lining can occur, the host pipe must be thoroughly inspected and cleaned. We use high-pressure water jetting and mechanical chains to remove roots, scale, and debris. This ensures the new liner bonds perfectly to the host pipe.
Tech Note: We use self-leveling CCTV cameras to map every inch of the pipe before proceeding.
Liner Impregnation (Wet Out)
A felt or fiberglass liner is custom-measured for your pipe. We then impregnate ("wet out") this liner with a specially formulated epoxy resin. The resin is rolled into the liner to ensure 100% saturation and uniform thickness.
Inversion & Inflation
Using compressed air or water pressure, the resin-saturated liner is inverted (turned inside out) into the existing pipe. This process presses the resin-coated side firmly against the walls of the old pipe, filling cracks and bridging gaps.
Curing
Once in place, the liner is held under pressure while it cures. Depending on the resin system, this can be done at ambient temperature or accelerated with hot water or steam. The result is a hard, structural pipe.
Reinstatement & Final Inspection
If there are branch lines connecting to the main pipe, we use a robotic cutter to reopen them from the inside. Finally, a post-lining video inspection confirms the quality of the installation.
