How to recognise it
A fractured or collapsed pipe reduces or closes the flow path and can allow soil to enter. Products and repeated clearance cannot rebuild the missing structure.
- Rapid repeat blockages
- Ground movement or subsidence
- Camera footage shows loss of pipe shape
Removal and prevention
The line normally needs cleaning and CCTV confirmation before excavation or another engineered repair is specified.
Repair the failed section and address contributing ground movement, loading or water ingress where identified.
- Match the tool to the pipe and material
- Verify full flow after clearance
- Investigate a fast recurrence
- Change disposal or maintenance habits where relevant
Step-by-step approach
- 1
Locate the affected section
- 2
Compare the signs with other possible causes
- 3
Choose a compatible removal method
- 4
Restore and verify normal flow
- 5
Prevent recurrence or arrange a condition survey
Important safety point
A symptom cannot confirm the pipe condition on its own. Stop DIY work if the route is unknown, tools jam, wastewater backs up or the blockage returns.
