Cured-in-place pipe (CIPP) lining is a trenchless technique used to restore damaged sewer or drain pipes without a full excavation. It is often preferred because it is cost-effective, less disruptive, and delivers long-lasting results. But what actually makes CIPP lining work? C. Lee Services discusses the tools, materials, and technology behind this widely used method of sewer line repair in Canton, OH.
Liners and Resins
An essential component of no-dig sewer pipe line repair is the liner, typically made of a flexible material such as felt, fiberglass, or polyester. The liner is impregnated with a resin, which can be either epoxy or polyester-based. The combination of the liner and resin creates a strong, durable shell within the damaged pipe, effectively sealing any cracks or holes and reinforcing the structural integrity of the pipe.
Inversion or Pull-In Methods
There are two primary ways to insert the liner into the existing pipe: inversion and pull-in-place. Inversion uses water or air pressure to flip the liner inside out as it enters the pipe, coating the interior. Pull-in-place uses winches or ropes to draw the resin-soaked liner through the pipe. Both of these methods utilized in trenchless sewer repair services rely on precision tools to ensure proper placement and fit.
Curing Equipment
Once the liner is in position, curing begins. Heat, steam, hot water, or ultraviolet (UV) light may be used depending on the type of resin. UV curing systems are becoming more common because they offer faster cure times and less disruption. The equipment used must maintain consistent temperature and pressure for the resin to cure properly.
Inspection and Quality Assurance
Advanced sewer camera equipment plays a key role before and after the trenchless sewer installation process. Technicians use them to inspect the pipe, confirm correct placement, and check for defects. Robotic cutters may also be used afterward to reopen branch lines if they were covered by the liner.
