Patch Lining & CIP (Cured In Place) Lining

Where defects are localised to a small area, a patch liner can be used to produce a permanent high quality repair. Patches are applied by coating a fibre glass mat with a resin. The mat is then wrapped around an inflatable packer and pushed into position. The packer is inflated and the resin left to cure. Where the drain is damaged along it’s length, the whole section can be lined. It involves the insertion of a lining “sleeve” impregnated with a polyester resin fibre along the length of the damaged drain. It is then moulded into place using air or water pressure and left to cure. The result is a new fibre reinforced pipe within the old damaged pipe.
