Pipe Lining
Here at South West Drains we use a no dig technique to reform and reline problem pitch fibre pipes. This entails
winching a piece of prefabricated metal (which is the exact size of the original pipe) through the blistered
and deformed pipe this process reforms the pitch fibre pipe back to its original shape.

Reforming & Relining
Once the prefabricated metal has been winched through the blistered and deformed pipe, we carry out high pressure water jetting to ensure pipe walls are clear and carry out a CCTV survey for confirmation.

A polyester liner which is impregnated with special resin is then inserted into the reformed pipe. The liner is then pulled/inflated the liner into position using compressed air. The inversion of the liner takes place which pushes the liner tightly against the existing pipe wall, again using water or air pressure.

Once the resin is cured and hardened, the result is a smooth and structurally sound pipe (which has the added benefit of being seamless which will stop any root ingress).

The new GRP liner inside your existing pitch fibre pipe will stop any future blistering and deforming. Once in place the liner causes a minimum loss of pipe diameter, approx. 6mm.
