London Drainage Patch Repairs

Patch repairs are a good, cost effective alternative to drain re-lining if only a small section of drain-pipe needs repairing. A good example of a small repair would be a slipped collar. What tends to happen in clay pipes is the mortar in the collar, which holds two drain pipes together cracks and falls out due to the pipes not being able to cope with movement under the ground. This can cause water to seep out of the open joint and into the ground beneath the collar, which eventually wears away at the soil then causing the collar joint to move and therefore cause a lip inside the pipe. The more ground beneath the pipe wearing away, the more chance that a larger section of pipe will crack or collapse which will require digging up and repairing. A simple patch repair will lift the joining pipes back in line with each other (once cured) and make the joint watertight.

If you have a larger length of pipe (Over 1000mm) that needs repairing then you will need to consider Drain Re-lining. Please Click Here to read more.
