About subsidence drainage repairs
What the work covers
Drain repair information for UK properties, including camera inspection, pipe relining and the part drain faults play in ground movement and subsidence.
A leaking or collapsed drain beneath a property can cause significant ground movement. When a pipe fractures, water soaks into the surrounding soil, carries fine material away and can open voids directly beneath a footing. Over time, a foundation above that void can drop, opening cracks in walls and causing floors to slope.
A specialist uses CCTV cameras to inspect drain runs from inside, checking for root intrusion, displaced joints, collapsed sections and any point where water is escaping into the ground. Where a fault is found, the repair may involve relining the pipe, replacing a section, or clearing a blockage. Catching a drain fault early can reduce the risk of more extensive foundation work being needed later. The specialist can provide a quote before any work begins.

Process steps
How the repair process unfolds
CCTV survey
A camera is passed through the drain to identify cracks, root intrusion, displaced joints and collapsed sections, with the full run recorded.
Written defect report
The specialist prepares a written report that grades every defect by severity and sets out the repair options available.
Repair works
The chosen repair method is then applied, which may be a patch liner, full structural lining, pipe replacement, or root-cutting followed by a flush.
Camera verification
Once the repair is done, a further camera run checks that the section is clear, watertight and sitting at the correct alignment before sign-off.
Signs that drainage repairs are needed
Does your property show these signs?
- Soil that remains soft or waterlogged near a known drain route even during prolonged dry periods
- Cracks that reappeared after cosmetic repairs were done without any check of the drainage below
- Sinking or movement that follows the path of a buried drain beneath the property
- A CCTV survey has identified a structurally compromised pipe that cannot be relined
- Ground movement that started around the same time a nearby drain blockage or pipe failure came to light
- Rainwater sitting against the foundation wall instead of moving away from the building
What's involved
What determines the scope of a drainage repair
CCTV survey findings
A CCTV camera passed through the drain pinpoints the precise position of any fracture, root intrusion or displaced joint. Knowing the exact fault position means the excavation goes straight to the problem rather than a broad estimated zone, keeping disruption to paths, driveways and planted areas to a minimum.
Pipe material and age
Clay pipes become susceptible to root ingress and joint failure as they age. Ground movement can cause concrete pipes to crack. Poorly installed plastic pipes tend to fail at the joints. The specialist considers pipe material when working out how a failure is likely to have occurred and which repair approach suits the situation.
Depth and access
A shallow drain running beneath a path is straightforward to expose and reinstate. A drain beneath a concrete slab or at considerable depth requires more work to expose, and the programme and scope reflect that. Once the camera survey has located the fault, the specialist explains what excavation the repair will involve.
Pipe relining as an option without digging
If the pipe wall is undamaged but joints have separated or the internal diameter has reduced, a resin liner applied from inside can recover flow without any ground disturbance above. The specialist assesses whether the pipe condition allows relining or whether open excavation is the only workable route.
