• Sewer Pipe Rehabilitation Solution

  A GFRP liner made of composite material with fiberglass and a specialized resin is utilized. This liner is inserted into the damaged pipeline using the pulling lining method, ensuring a tight fit against the existing pipeline wall. UV heating is applied to solidify the resin, creating a strong and smooth inner lining that restores the pipeline's functionality.

  The CIPP (Cure in Place Pipe) technique is employed to minimize disruptions during repairs. The GFRP liner is installed through existing manholes, eliminating the need for extensive construction. After UV curing, the damaged pipeline is renewed with a smooth inner lining, improving sewer water transportation.
