In the past, damaged drains were a difficult problem to solve. Not only was it hard to detect issues with underground pipes, but it also meant the laborious job of excavating them. This could be particularly difficult and disruptive if affected pipes were underneath roads or walls.
However, advancements in technology now mean underground drainage issues can be rectified far more easily and quickly thanks to a process known as drain relining.
What is drain relining?
Drain relining involves repairing damaged pipes without having to dig them up and reinstall them. A new pipe is created inside an existing one to help seal cracks and force water to flow more efficiently. Drain relining can target the problems of open or leaking joints or cracks caused by blockages. Root intrusion, one of the biggest causes of drainage problems, can also be tackled through drain relining.
How does the process work?
There are several methods of drain lining. Drain lining can be carried out by using a Cured in Place Pipe (CIPP) lining. In this process, a special reinforced resin layer liner is cured to the inner surface of the drain. Ultra Violet lining (UV lining) uses ultraviolet light to cure a reinforced liner to a damaged drain, while GRP (glass reinforced plastic) linings are one of the most common drain relining techniques. In all cases, a thorough drain inspection should be carried out first to understand any issues and the best solution.
