Drain Relining

PDS NW Ltd are able to carry out full length lining and localised patch liners on pipes, drains and sewers. This provides a permanent quality repair in a convenient cost effective way, allowing work to be carried out with minimal distruption and inconvenience to the customer. Using our CCTV systems we can locate any problem areas and ensure that the client is getting a quality job.

How does it work?

Full length lining

A resin impregnated felt is pulled into place and inverted using either water or air. Upon curing, the inversion tube is withdrawn and this creates a pipe within a pipe. If there are any incoming lines these can be exposed using a mechanical cutter.

Patch lining

A resin impregnated fibreglass sheet is placed onto an inflatable tube and pushed into place, once the patch is in the desired location the inflatable tube is then blown up and left in situ until resin has cured, see examples on the right ⇒
