What drain repairs & relining involves
Drain repairs address visible defects such as cracks, open joints, root damage, deformation or collapsed sections. A camera survey is commonly used to locate the defect and establish whether relining, a local repair or excavation is the more suitable option.
When it may help
- A drain that blocks repeatedly
- Visible movement, sinking or damage around a drain
- Root intrusion or open joints
- Cracked, deformed or collapsed pipework
How it is assessed
The defect is assessed using the available survey information. For suitable pipes, a local repair or liner can be installed from within the drainage system. Where the pipe has failed extensively or access is unsuitable, excavation may be required.
What to expect
Before an engineer arrives
Share any existing survey footage, reports and information about the location of the suspected fault. This allows the engineer to assess whether further inspection is needed.
Timing
Repair duration depends on the pipe condition, location, access and chosen method. The repair method, preparation and curing or reinstatement time should be set out in the quotation.
What affects the price
Price is affected by the length and severity of the defect, the method selected, access, ground conditions and any reinstatement needed after excavation.
Excavation and alternatives
Relining can avoid excavation in some situations, but it is not suitable for every defect. A collapsed pipe or inaccessible section can require excavation and replacement.
Common questions
When is drain relining an option?
Relining can be considered where the pipe shape, condition and access allow a liner to be installed. A survey helps determine whether it is appropriate.
When is excavation needed?
Excavation may be needed where a pipe has collapsed, access is unsuitable for an internal repair, or the damage cannot be reliably repaired by relining.
Why is a camera survey useful before repair?
It helps locate the defect, assess pipe condition and select a repair approach based on the actual drainage run.
