Trenchless drain relining in London is a drain repair system where instead of removing a damaged drain, an internal liner is bonded inside the pipe giving extended life and a complete sealed repaired pipe. Patch repair is a system for repairing short lengths of pipe where a small inner pipe is essentially expanded into place and bonded to the leaking pipe.
Drain Relining in London
CIPP (Cured-In-Place Pipe), 'trenchless' and 'no-dig' are names used for the same pipe repair system so don't be baffled; it is a long lasting solution that can be applied quickly and with minimal disruption when compared to a complete drain replacement.
Pipes are damaged typically by tree root ingress, settlement or movement where the pipes split at the joints. The original pipe is first cleared of major blockages and a new material is pushed down the leaking pipe. This material is pulled through the section to be repaired and is impregnated with a resin and later a hardening catalyst. The new liner is expanded inside the pipe using air or water pressure and forms the shape of the existing drain with a minimal reduction in flow capacity (as the pipe diameter is reduced slightly). It cures or hardens against the existing pipe and the liner is designed to be usable immediately after curing.
Sewer Drain Relining
Pipe relining in London is a fast operation and is suitable for both horizontal and vertical pipes that are exposed to standard rainwater or sewer use.
Patch repair is used where just a small piece of pipe needs to be repaired. A small 'tube' of material is inserted in the patch area and is inflated and bonds to the inside wall of the damaged pipe. This type of repair is only for small sections of pipe.
