Relining and Repair
Rely on us to provide the best possible results!
If your drains are cracked or deteriorating, it is only a matter of time before you will be facing serious drainage problems. Damaged pipes put your property at risk of sewer flooding, leaking, blockages, foul odours and water egress that can contribute to subsidence — all issues that get worse with cumulative wear and tear.
It is essential to get damaged drains and sewers repaired without delay. But digging up and replacing large sections of pipe can be inconvenient, not to mention costly. Fortunately, there is another way, and our default position, in most cases, is to install a cured-in-place pipe (CIPP) repair or liner, which is cost-effective and minimises disruption.
With CIPP relining, we make long-lasting fixes and improvements to pipe interiors without the need to dig. (No surprise that this is also known as ‘no-dig technology’).
Whilst resolving the immediate problem, CIPP also heads off the chance of further issues in the repaired pipe for years to come.
MZR Drainage has many years of experience in delivering this technology, so you can always rely on us to provide the best possible results with the least possible fuss – we are also on call 24/7 meaning we’re available to fix your needs whenever you need us.
What is involved in CIPP pipe repair?
These ‘no-dig’ or ‘trenchless’ pipe replacement methods involve inserting a liner impregnated with a special resin into a vertical or horizontal sewer or drain. This works for pipes up to 1.8-metres in diameter. Once inside the pipe, the liner is turned inside out and forced through using either water or air pressure; the liner is pushed out to bond with the interior of the pipe and the resin is cured or hardened. This creates a new pipe within the old pipe, restoring the integrity of the drain or sewer.
Once the CIPP liner has been installed, any lateral (branch) connections mapped prior to the lining being fitted, are opened using advanced robotic cutters.
Using this CIPP method, we rehabilitate sewers and drains from 100mm to 1,800mm in diameter, accessing the pipe from manhole chamber to manhole chamber. For localised repairs or short sections of the drain, we may employ CIPP patch (or point repair) lining. This involves positioning a ‘patch’ (short piece) of CIPP liner which is wrapped around an inflatable packer. Once in place, the packer is inflated leaving the patch to form a new lining to that section of pipe. Several patches may be fitted end to end to make a longer repair.

Frequently Asked Questions About CIPP Relining & Drain Repair
CIPP (cured-in-place pipe) relining is a no-dig drain repair method. A flexible resin-soaked liner is fed inside the damaged pipe, inflated against the pipe walls, and cured in place to form a seamless new pipe inside the old one. The result is a structurally sound, watertight repair without excavation.
No – that’s the main advantage of CIPP. Relining is carried out through existing manholes, inspection chambers or rodding access points, so there’s no need to dig up driveways, paving, lawns or floors. It’s the lowest-disruption option for repairing a damaged drain.
A correctly installed CIPP liner has a design life of around 50 years, in line with manufacturer specifications. The cured liner is corrosion-resistant, root-resistant and structurally independent of the host pipe, which means it continues to function even if the original pipe deteriorates further.
In almost every case, yes. Excavation, pipe replacement, ground reinstatement, and replacing damaged paving or driveway are the costly parts of a traditional repair. CIPP avoids all of that. The relining itself takes longer than a simple patch, but the total project cost is significantly lower.
Relining fixes hairline cracks, fractures, displaced joints, root-ingress damage, leaks, internal corrosion and pinholes. It’s also used to upgrade old clay, pitch-fibre and cast-iron pipework. It cannot fix a fully collapsed pipe with no remaining bore – that requires excavation and replacement.
Most domestic CIPP relining jobs are completed in a single working day, including pre-survey, prep, install and curing. Larger commercial projects covering long pipe runs may extend to 2 to 3 days. The drainage system is back in normal use the same day in most cases.
CIPP works on the majority of domestic and commercial drainage – clay, cast iron, pitch-fibre, concrete and PVC, in pipe sizes from 100mm upwards. It’s not suitable where the pipe has fully collapsed, where the bore is so badly displaced that the liner can’t inflate evenly, or where access is severely restricted.
The liner adds a few millimetres to the pipe wall, so the bore reduces slightly. In practice, the new lining is smoother than the old pipe, which improves flow – so relined drains usually carry water just as well as, or better than, the original.
