Say Goodbye to Drain Digging: Re-lining Solutions for London

What is a Drain Lining?

What is a drain lining ? A drain lining is a length of PVC coated fibreglass reinforced felt tube of 3mm to 6mm thickness that is typically for use within diameters of pipe from 75mm up to 375mm. The internal felt material of the sleeve is impregnated with a precise and controlled mixture of polyester resin, activating catalyst and accelerator. The resin and chemical mixture is absorbed into the inner felt of the liner and then the lining is either pulled or pushed into the damaged drain to be lined.

Once in place the drain lining is inflated by inserting an inflation hose which is pressurised by air and slowly rolled through shaping the liner to the host drain pipes inner walls and surface characteristics ready for solidification of the resin and chemical mixture curing process. When the curing process is complete and the lining has hardened the end result is a drain within a drain and an air and watertight seal between the liner and original drain.

Why Use a Drain Liner? 

Lining an underground drain saves precious time and money when restoring the structural integrity of cracked or fractured clay-ware pipes and sealing leaking sections of a drainage system or open pipe joints. We also cure the infiltration of root ingress that grows within a damaged drain run by installing resin impregnated drain linings. We deal with complete drainage system restoration as well as isolated damage patch lining repairs equally as efficiently.
