When Does a Commercial Drain Need Excavating?
Excavation is not automatically required whenever a damaged drain is found. CCTV surveys and no-dig repair methods may be suitable for some defects.
There are situations, however, where physical access to the pipework is necessary.
The most suitable repair will depend on the condition of the drainage, where the defect is located and what surrounds the affected pipework.
This can include:
Collapsed drainage pipework
Severely cracked or broken drains
Badly displaced pipe joints
Sections that have lost their alignment
Extensive root damage
Drainage affected by ground movement
Pipework unsuitable for a patch repair
Drainage that cannot be accessed internally
Damaged chambers and connections
Sections requiring complete replacement
What Can Drain Excavation Involve?
Localised Pipe Repairs
A short defective section can be exposed and removed while retaining surrounding drainage that remains in suitable condition.
Collapsed Drain Excavation
Where a pipe has completely collapsed, excavation may be required to remove the failed section and restore the drainage route.
Drain Replacement
Longer sections of deteriorated or damaged pipework can be replaced between suitable connection points.
Manhole & Chamber Repairs
Damaged chambers, connections and surrounding pipework may need to be exposed so repairs can be completed correctly.
Drainage Alterations
Excavation can also be used where existing commercial drainage needs to be redirected, upgraded or connected differently.
Excavation may be required where drainage has collapsed, suffered substantial structural damage, become badly displaced or cannot be repaired effectively from inside the pipe.
Yes. Where appropriate, CCTV drain inspection and drain tracing can help establish the position of a defect before excavation begins.
No. Some localised defects may be suitable for a no-dig repair. The type and extent of the damage need to be assessed first.
Yes. Where a section has collapsed beyond repair, it can be excavated and replacement drainage installed.
Where the defect can be accurately located, excavation can often be focused around that area rather than unnecessarily exposing the entire drainage run.
Yes. Commercial drainage commonly runs beneath parking areas, yards and hardstanding. Access, safety and reinstatement requirements need to be considered when planning the work.
Yes. Damaged chambers and drainage connections can be investigated and suitable repair work carried out where required.
Yes. The repaired drainage can be checked before the excavation is closed to confirm that the affected section is flowing correctly.

No-Dig Repairs Where Suitable
Excavation is not always necessary.
Where the pipe remains structurally suitable and the damage is limited to a localised area, a no-dig patch repair may sometimes provide an alternative.
Depending on what the investigation shows, Drain Reaction can also provide:
CCTV drain surveys
Drain tracing
High-pressure water jetting
Drain cleaning
No-dig patch repairs
Localised repairs
Drain replacement
Planned preventative maintenance
We can explain the available options once the condition of the drainage is understood.
