Targeted Drain Excavation for Commercial Properties
Some drainage defects cannot be resolved from inside the pipe. Where a drain has collapsed, become severely displaced or suffered substantial structural damage, excavation may be required to expose the affected section and complete a lasting repair.
Drain Reaction provides commercial drain excavation across the North West, working with businesses, landlords, property managers and facilities teams to investigate damaged underground drainage and determine the most appropriate repair method.
Our focus is on keeping excavation targeted. Where the position of the defect can be established beforehand, the affected drainage can be exposed without unnecessarily opening up larger areas of the site.
CALL 01613 275 092 →When Is Drain Excavation Necessary?
Excavation is generally considered when the condition or position of the drainage means an internal repair is not appropriate.
Collapsed drainage pipework
Severely cracked or broken drains
Badly displaced pipe joints
Sections of pipe that have lost their alignment
Extensive root damage
Drainage that cannot be accessed internally
Defects unsuitable for patch lining
Pipework requiring complete replacement
Damaged manholes or inspection chambers
Drainage affected by significant ground movement
Where possible, we can investigate the drainage before excavation so the work can be focused around the affected section.
Targeted Excavation Starts
With Accurate Investigation
Opening the ground should not be the first step where the location of the problem is unclear.
Before excavation, commercial drainage may be investigated using CCTV inspection, drain tracing and existing access points to establish where the damaged section sits within the system.

What Can Drain Excavation Involve?
The work required will depend on the drainage defect, surface above the pipe and accessibility of the site.
Localised Pipe Repair
A damaged section of drainage can be exposed so the defective pipework or joint can be removed and replaced.
Drain Replacement
Where a longer section has deteriorated or collapsed, replacement drainage may be installed between suitable connection points.
Collapsed Drain Excavation
A completely collapsed pipe may need to be excavated to restore the drainage route and reconnect the system.
Manhole and Chamber Repairs
Damaged inspection chambers, manholes or connections may require excavation to expose and repair the surrounding drainage.
Drainage Alterations
Excavation can also form part of alterations where existing commercial drainage needs to be redirected, replaced or connected differently.
Excavation may be required where drainage has collapsed, suffered extensive structural damage, become severely displaced or cannot be repaired effectively from inside the pipe.
Yes. Where appropriate, CCTV inspection and drain tracing can be used to help identify the position of a defect before excavation begins.
No. Some localised defects may be suitable for a no-dig repair. The condition and type of damage need to be assessed before the most appropriate method can be determined.
Yes. Where drainage has collapsed beyond repair, the affected section can be excavated and replacement pipework installed.
Commercial drainage frequently runs beneath hardstanding, yards and parking areas. The surface and site access need to be considered when planning the excavation.
Yes. Where damaged chambers or drainage connections require excavation, we can investigate the problem and advise on the appropriate repair.
Where the location of the defect can be accurately identified, excavation can often be concentrated around the affected section rather than unnecessarily exposing the entire drainage run.
Yes. The repaired drainage can be checked before the excavation is closed to help confirm the system is flowing correctly.
Yes. Drain Reaction works with businesses, commercial landlords, managing agents, facilities teams and organisations responsible for commercial premises.
