What causes a collapsed drain?

The most common causes of collapsed drains include tree-root ingress, ground movement, freezing temperatures, frequent blockages and general wear and tear.

Key signs of a collapsed drain

Whilst a collapsed drain is not always obvious, there are a number of warning signs. These include slow-running drains, a smell of sewage, sinking ground in the garden and signs of dampness.

How to get it diagnosed?

Whilst there may be some obvious signs, identifying exactly which drain has been damaged and the extent of the damage requires specialist involvement in the form of a drain expert who will conduct a CCTV drain survey.

How is it fixed?

Depending on the exact damage and the state of the pipes, there are several options. The first involves relining the broken pipe with a resin-coated tube, effectively creating a new pipe inside the old one. The second (rather extreme) option is to re-route the plumbing to avoid the damaged drain. If the pipe is damaged beyond repair, it will need to be replaced entirely.
