Southern Relining Services uses a GRP liner which is a UV light-curing pipe liner for trenchless long-lasting pipe rehabilitation with a service life of at least 50 years. The liner system comprises a glass fibre reinforced sleeve which is impregnated with a UV-cure polyester resin. Ordered to specific diameter widths and features a stretch capability that means the manholes do not need to be scanned before works. The system provides additional external protection with its two-layer, fibre-reinforced design that protects the liner against damage before, during and after installation.
