Pipe Lining

Pipe lining is a tried and tested method used to restore the structural integrity of damaged pipes and drains without the chaos and disruption caused by excavation.

Other reasons for the use of pipe lining are that it may just be totally impractical to excavate due to its location or its depth.

Damage to pipe work can occur through a vast range of reasons, the most common being tree root infestation and voids created by running water around the pipe. There are also situations where broken pipes are allowing ground water into a drain. Again this brings with it the problem of ground silt infiltration and excessive water.

Lining is recognised as the most ideal solution for sealing pipes even though no other structural defects are present.

Plas Gwilym Environmental has the capability of lining pipes with diameters ranging from 75mm to 1000mm we also have an extensive range of lining options available to suit specific applications and locations. The style of lining procedures can range from thermally cured Epoxy Resin systems where hot water is used to harden the resins or ambient temperature cure where the liner cures under normal conditions and time constraints aren’t a working factor.

Plas Gwilym Environmental offer several other non intrusive alternatives to excavation, including Localised Structural Repair (LSR, Resin Injection (RI) and Inspection Chamber Rehabilitation (ICR).

LSR or ‘patch’ repairs are closely linked to the lining procedure, but are only used where a drainage line has a small localised break or a poor joint allowing it to become either a catch hazard for waste or a break allowing soil, water or tree roots into the drainage line.

RI is a process where a waterproof expanding resin product is injected into the brickwork of a chamber, preventing water ingress and restoring its structural integrity.

In the ICR process a water tight coating is applied to the walls of an inspection chamber, which prevents any water ingress and aids the structural integrity of the chamber.
