Our pipe relining company in cape town attempts to repair your pipes by curing them from the inside using a special resin, which cures with time in order to form another strong (in some cases, even stronger than the original) pipe.
In this method, the resin is the key to curing the pipe. A resin-saturated felt tube made out of a suitable material (generally polyester or fiberglass) for resin impregnation, is inserted into a damaged pipe. This resin then hardens and forms another pipe within the damaged pipe.
The insertion takes place from an access point which is upstream. Inserting from a downstream access point is possible, but it is riskier and hence avoided.
Pipe relining is considered a trench-less technology, since minimal to none digging is involved in this trench-less process. This makes relining a more cost-effective and less intensive method than traditional “dig and replace” pipe repair methods.
