Drain Relining

Drain Relining Explained

Drain relining or non-dig technology is a proven way to repair damaged drains without excavation, giving the benefits of minimal disruption combined with the fastest and most cost-effective way to repair a damaged drain. It involves installing a new pipe or lining which bonds to the inside of the damaged pipe by a method known as inversion. This uses water or air pressure to fit the lining tightly against the wall of the damaged pipe restoring the free flowing function of the drain or sewer.

Lining applied to damaged drains prevents further deterioration of the drains and so eliminates any leaks into the surrounding ground which could lead to subsidence. The drain lining process is approved by local authorities, surveyors, civil engineers, and architects. Our drain relining works carry a 10-year guarantee.
