Drain relining uses the latest trenchless technology to repair leaking drainage without the expense and disruption of excavation. This system is suitable for drainage that has suffered from cracking, fracturing or general wear and tear.

Drain relining is usually used on drainage that is situated beneath a building or road where the cost and disruption is at a large scale. For example, drain relining has excellent applications in the repair of drainage within protected structures. It is a very efficient method where sections can be repaired in a couple of hours.

The basic principle is to introduce a tough polyester tube into the old drain. The liner is impregnated with resins and then dragged into the damaged line. The liner is then inflated under pressure by a specialist calibration hose and is kept under pressure until the resins have cured ensuring maximum contact with the original pipework and the liner has become solid. The calibration hose is then removed and the pipe has been sealed, reinforced and smoothed out to leave a water tight pipe.
