Pipe relining repairs a damaged drain without digging it up. A flexible liner soaked in resin goes inside the pipe and presses against the walls. Once the resin hardens, it forms a smooth new pipe inside the old one, which can seal cracks and block roots. Because it usually needs no trench, gardens, patios, and drives often stay untouched.
A CCTV survey maps the damage. Since relining only suits some faults, the survey shows if it will work. It also shows how long the damaged section runs.
High-pressure jetting clears deposits and roots from the pipe. A clean surface matters, because the resin must bond to it. Skipping this step can cause the liner to fail.
The engineer pulls the resin liner into place and inflates it against the walls. As a result, the liner takes the shape of the old pipe. This is why a close fit matters.
The resin hardens into a rigid lining. Ask for a final camera check, so you can see the finished pipe. Since the footage shows any flaws, it also gives you a record.
The cost of relining depends on the pipe size, its length, and how easy it is to reach. A short repair usually costs less than a long run. Relining can cost less than digging, since there are no surfaces to rebuild. However, that depends on the job, so ask for a written quote and compare it with digging.
Makers design a cured liner for many years of use. The exact life depends on the product and the job. Since claims differ, ask the contractor for the product's design life and what guarantee they offer.
No. Relining suits many faults, such as cracks, root damage, and displaced joints. However, a pipe that has fully collapsed may need digging instead. A CCTV survey shows which method fits.
Relining is far less disruptive than digging, since it works through existing manholes and access points. Your garden and drive usually stay as they are. Ask how long the job will take for your pipe.
