Signs of a pipe relining problem
- ✓ Cracks or root gaps show on a camera survey
- ✓ A drain blocks again after each clear-out
- ✓ Joints have moved or leak
- ✓ Damp or smells appear near a drain run
- ✓ You want to avoid digging up a patio or drive
Pipe relining repairs a damaged drain from the inside. A flexible liner soaked in resin goes into the old pipe. It sets hard and forms a new wall within the old one. Because the liner sits inside the pipe, it needs little digging.
It suits cracks, root gaps and worn joints. Because it needs little digging, it can spare gardens and drives. However, it does not suit every pipe, so a camera check should come first. A collapsed pipe is one case where it may not work.
A lined pipe has a slightly smaller bore than before. A collapsed or badly shifted pipe may need digging instead. Ask the engineer why relining suits your pipe, and what cover comes with it. Still, ask for a digging quote too, so you can compare.
Price depends on the length of pipe, its size and the state it is in. Cleaning and access work can add time. Since digging is the other route, ask for both quotes. Compare them in writing.
Usually only small access holes, not a full trench. The exact work depends on the pipe. Ask the engineer where any holes would go. However, a badly damaged pipe may still need a dig.
It can mend cracks, gaps and worn joints. It does not mend a pipe that has collapsed or shifted badly. A camera survey shows which case you have. Because each pipe differs, ask the engineer to explain.
Relining usually means less mess, while digging replaces the whole length. The right choice depends on the fault and the pipe route. Ask for both options in a written quote. Then compare the cover on each, since it may differ.
