Drainage pipes can become damaged over years of use at the sections where they join together. The connection points of drainage pipes are unfortunately one of the weak points in the drainage system. However, if you discover that one of these points is damaged in your drainage system, you don’t have to worry about a messy excavation. Sometimes, this damage can be repaired in situ by carrying out a liner repair.

A drainage pipe liner repair is a method of repairing a drainage pipe in situ. A liner is inserted into the system at the point of damage and bonds the damaged pipe together fully repairing the pipe.

The liner, much like a sock, is blown into the damaged pipe and sited at the exact point of damage. It is coated with epoxy resin which sets hard and bonds the liner to the pipe walls. This means that even small cracks and fractures can be sealed using a liner repair.

When a liner is inserted into the pipe, a small amount of cross sectional area will be lost, but what you get in increased flow of waste products, outweighs this loss in diameter.

A liner repair is a brilliant way to repair damaged drainage pipes, without the mess or trouble of completely replacing the section of damaged pipe.
