WHAT IS DRAIN RELINING?
As drainage related problems go, damaged drain pipes rank among the most bothersome of the lot. Apart from the fact that they are notoriously tricky to detect at the outset, leaky drain pipes also damage the environment by polluting the soil.
In the past, the only way to fix damaged drain pipes was the long and expensive process of excavation and replacement. This was a notoriously difficult process as more often than not, the damaged pipes were usually buried metres under the ground. Sometimes buried under infrastructure like roads, driveways or retaining walls.
Today, however, thanks to modern technology, drainage pipes can be fixed via the relatively easier and cheaper method known as drain relining.
Process Of Drain Relining
The process of drain lining begins with the inspection of drainage pipes. Unlike the old method of drain replacement which involves excavation of pipes, the drain relining process makes use of CCTV survey technology. This inspection determines the location and extent of any damage to the pipes.
CLEARING OF DEBRIS
After the inspection, the pipes are cleaned to prevent any obstruction during the relining. The intrusions (tree roots for example) are removed using a robotic cutter which can cut through even steel and concrete. After this, a high-pressure water jetter is used to clear the pipe of any debris. This ensures a good bond on the pipe wall.
