Sewer Relining

Sewer relining is a trenchless pipe rehabilitation method where a flexible, resin-saturated liner is inserted into a damaged sewer pipe and cured in place to form a new, seamless pipe within the old one. The liner is hardened using UV light, hot water, or ambient curing, creating a structurally independent pipe with a smooth interior surface.

The main advantage of relining over traditional pipe replacement is that it avoids excavation. There is no need to dig up the yard, driveway, or floor structures, which dramatically reduces disruption and cost. The work can typically be completed in a single day, and the building's plumbing system is back in operation within hours.

Relining is suitable for most pipe materials and diameters, including cast iron, concrete, clay, and PVC pipes from 50 mm to 300 mm. It effectively seals cracks, eliminates root intrusion points, and bridges misaligned joints. A quality relining extends the sewer's service life by 30 to 50 years and comes with a long-term warranty.

Before relining, the pipe must be thoroughly cleaned and inspected with a camera. Not all pipe conditions are suitable for relining — severely collapsed sections or pipes with sharp bends may require traditional excavation and replacement. A qualified sewer contractor can assess your situation after a camera inspection.
