Collapsed Drain Repair
Recurring blockages, sinkholes or sewage backing up can signal a collapsed drain. We confirm it, locate it precisely, and fix it.
A collapsed drain is one of the more serious drainage faults — and a common cause of persistent blockages, foul smells, damp and even subsidence or sinkholes. The signs are easy to misread, so the first step is always to confirm and locate the collapse on camera.
Depending on the extent and location, we repair by relining where the pipe profile allows, or by targeted excavation and replacement of the failed section.
Why it matters
Accurate location
We pinpoint exactly where the collapse is, so any excavation is minimal and targeted.
Right method
Reline where possible, excavate only where necessary — no over-digging.
Address the cause
Collapses often follow root damage or age; we fix the section and advise on the rest.
How it works

Confirm on camera
A survey confirms the collapse and rules out a simple blockage.
- 02
Locate precisely
We trace and mark the exact position and depth.
- 03
Repair
Relining or a targeted excavation and replacement restores the run.
Collapsed Drain Repair — your questions answered
How do I know if my drain has collapsed?
Common signs are repeated blockages, slow drainage, foul smells, damp patches and, in severe cases, subsidence or a sinkhole. A camera survey confirms it.
Will you have to dig?
Not always. A partial collapse can sometimes be relined; a full collapse usually needs a targeted excavation of the failed section only.
