Drains don’t always have to be excavated to make repairs; they can be lined using a structural drain lining material.

If your drainage company has found that a drainage pipe leading away from your home is damaged, they will offer various solutions to repair the problem. The first being to excavate the pipe and replace the damaged section. This is the more traditional approach to broken drainage pipes and can be a good solution in some instances. However if the drainage pipe is inaccessible due to it running under your newly laid driveway, or if excavation is not possible due to space constraints, the drainage company may suggest a liner repair.

To carry out a liner repair, the drainage company will insert a resin impregnated liner in the pipe. This is blown along the pipe to the desired location and the liner is then inflated so it moulds to the internal dimensions of the pipe. This is then allowed to set in situ until completely dry.

A pipe with a liner fitted will be slightly smaller in diameter than it was when new, but the increased flow will mean that the difference will be unnoticeable.
