Once we have diagnosed the problem and found the area it is situated in, we will start repairs. The repair we perform always depends completely on the situation. For example, if the problem is only a small crack, we can do a pipe relining, which will mean we do not have to excavate, or take out any surrounding pipework. We just cover the inside walls of the pipe with a special resin that hardens and essentially creates a pipe within the pipe. This solution is used in most circumstances.
However, in other circumstances this would not be possible. For example, a damaged drain that has been allowed to leak for too long and damage surrounding areas, or in cases of catastrophic failure. These would require a full drain replacement. In these instances we would make sure to keep disruption to a minimum and get the work done as efficiently, quickly and thoroughly as possible.
