We install CIP liners from 75mm – 225mm in diameter in most materials. Our stock is reviewed and changed regularly to keep up with this market which is changing and providing better quality lining materials constantly. Our stock is reviewed and changed regularly to keep up with this market which is changing and providing better quality lining materials constantly, eg ‘no wrinkle’ or ‘odourless’. We can install short patch liners to long pipe sections in below ground drainage, stacks and other above ground pipework using air inversion or water techniques as necessary.

Lining material is basically felt and when formed it will be similar to GRP (Glass Reinforced plastic). It is impregnated with a resin mixed with an accelerator and a catalyst and inserted into the host or damaged pipe section. It is then inflated until the resin cures and once formed it provides a structurally sound repair.

These are recognised and approved repairs by the WRc (Water Research Council) and local authorities, surveyors etc and can reduce the cost of remedial work considerably, as opposed to excavations.

They will cause minimal disruption and systems can be in use within hours of their installation. Liners are usually the best way to restore the structural integrity of damaged pipework and they will also offer improved flow characteristics. Sections will be installed in one length without joints, this prevents root re-growth and water infiltration etc.

Liners are not just used for pipe repairs, they can also be utilised to seal off redundant below ground junctions that, for example, may be allowing smells, water loss or rodent access.

Images below: installing a liner through a roof outlet which was leaking at a defective joint just below the roof surface. This joint was not easily accessible and this method prevented exposing and replacing the outlet and defective joint.
