Pipe patching – the quick affordable solution.
The process if very similar to doing a full relining except if the installation is in one or two meter lengths to mend the breakages or misalignments. If it’s not economical to reline the entire pipe , then we would recommend using the relining for pipe patch repairs. If several patches are required then relining the entire drain may be better value for money.
How does pipe patching work?
Fixing damaged sections of pipes have traditionally meant digging a trench to access the damaged sections. By using the lining as a pipe patch your saving money, time and even better you don’t have to dig a trench.
