Collapsed drain repair
Collapsed drain repair is usually investigated when visible signs begin affecting reliability, safety, or day-to-day operations. Understanding causes and risks early helps you decide whether a targeted fix or a wider scope is the right move.
A clear diagnosis early usually limits disruption and cost, so you can choose a repair route that fits your programme and budget. When you are ready to discuss delivery, start with the CCTV Drain Surveys service overview.

What causes this drain problem
Drains collapse due to age, ground movement, tree root ingress, heavy traffic over shallow pipes, or damage during construction. Clay pipes are especially prone to cracking and collapse over time.
When to take this seriously
This is typically needed when recurring symptoms, project risk, or compliance concerns mean a patch repair is no longer a reliable option.
Quick checks you can try
Look for sinkholes, dips or cracks in paving, or patches of grass that stay unusually green. Check if multiple sinks, toilets or gullies are slow or backing up. If only one fixture is affected, the issue may be local; multiple outlets suggest a shared run problem.
Signs this issue is becoming serious
Sinkholes, sewage on the ground, or a sudden drop in drainage across several fixtures are strong signs of a collapse. Recurring blockages and foul smells that persist after clearing also suggest structural failure. These need a CCTV survey and repair, not just unblocking.
Practical path to a reliable repair
We use a CCTV survey to confirm the extent and position of the collapse. Repair options include excavation and replacement of the failed section, or relining where the pipe is still structurally suitable. We reinstate surfaces after work.
What affects cost and complexity
Cost and complexity usually depend on access, scale of remedial work, existing condition, and whether supporting works are needed to complete the fix safely.
When to call a drainage engineer
Call a professional if you see sinkholes, persistent blockages, foul smells, or slow drainage from multiple outlets. Do not delay—collapses can worsen and cause subsidence or flooding.
