No-Dig Drain Lining to Strengthen and Protect Damaged Drains
Drain lining is ideal for repairing cracks, leaking joints, root-damaged sections and weakened pipework — without major excavation, where suitable.
Drain lining (also known as cured-in-place pipe lining, or CIPP) creates a strong new pipe within your existing pipe. It is one of the most cost-effective and least disruptive ways to repair a damaged drain — provided the structure of the pipe hasn't been completely lost.
What is drain lining?
A flexible felt liner is impregnated with structural resin and inserted into the damaged pipe. It is then inflated and cured — using ambient, hot water or UV — to form a smooth, joint-free pipe inside the old one.
When is drain lining suitable?
Lining works extremely well for the most common drainage problems we encounter, provided the original pipe still holds its shape.
- Cracked clay or concrete drains
- Open or displaced joints
- Root ingress through joints or fractures
- Leaking pipework
- Early-stage pitch fibre deformation
- Worn or eroded pipe walls
What problems can it solve?
Drain lining seals the pipe internally, restores structural integrity and stops further deterioration. It also creates a smooth bore that improves flow and resists future blockages.
Why line before collapse?
Once the pipe loses its shape — for example, after full collapse, severe ovality or large missing sections — lining is no longer viable. At that point, excavation becomes necessary, which is significantly more disruptive and expensive.
Drain lining vs excavation
Excavation involves digging up driveways, patios, gardens or floors to expose and replace the damaged pipe. Lining typically requires only access through existing manholes or rodding eyes — meaning your property usually stays intact.
Drain lining is most effective when used before the pipe fully collapses. Once the structure of the pipe is completely lost, excavation may be required. Early CCTV inspection gives you the best chance of a less disruptive repair.

If you have recurring blockages, bad smells, slow drainage, signs of subsidence, damp patches, or old pitch fibre drains, it is better to inspect the problem early.
