Drain Relining in Dorset
No-dig structural drain repairs with significantly less excavation and disruption
Drain relining can provide an effective way to repair damaged underground pipework without excavating the full length of the drain.
Dorset Drainage Services provides relining for commercial premises, industrial sites, managed properties and domestic drainage where the existing pipework is suitable for rehabilitation.
Commercial Drain Relining
Repair underground drainage while reducing disruption above ground
Excavation across roads, car parks, buildings, production areas or landscaped sites can create considerably more disruption than the original drainage problem.
Where conditions allow, relining enables damaged drainage to be rehabilitated primarily from existing access points.
This can be particularly valuable for:
- Commercial premises
- Factories and industrial sites
- Retail environments
- Car parks
- Managed estates
- Schools and public buildings
- Housing developments
- Pipes beneath buildings
- Driveways and landscaped areas
What Problems Can Drain Relining Address?
Relining may be considered for suitable drainage affected by:
- Cracks
- Root ingress
- Defective pipe walls
- Deteriorating pipework
- Blistered pitch fibre
- Leaking sections
- Localised structural deterioration
A CCTV survey will normally be important in determining the condition of the pipe and whether relining is an appropriate solution.
How Drain Relining Works
The exact method depends on the existing drainage, but the process can include preparation of damaged pipework, insertion of an impregnated liner, forming the liner against the existing pipe and allowing it to cure.
01
Survey
We establish the location and condition of the defect.
02
Prepare
The drainage is cleaned and prepared for the liner.
03
Install
The liner is positioned inside the existing pipe.
04
Cure
The lining is formed against the existing drain and allowed to cure.
05
Inspect
The repaired section can be checked before the system is returned to normal use.
Why Consider No-Dig Repair?
01
Reduced excavation
Large stretches of ground may not need to be opened.
02
Less site disruption
Particularly valuable beneath occupied or operational areas.
03
Access difficult locations
Relining may be possible where conventional excavation would be complicated.
04
Structural rehabilitation
The method creates a new lining within the existing pipe.
05
Reduced future root ingress
A correctly installed structural liner can remove defective joints and openings through the repaired section.
Root Damage & Relining
Tree roots entering defective drainage can create repeated blockages. Specialist high-pressure equipment can be used to remove root intrusion before the condition of the pipe is assessed for further repair.
Does the same drain keep blocking?
A CCTV inspection can help establish whether root ingress or structural damage is causing the problem.
Relining or Excavation?
Relining will not be appropriate for every damaged drain. If the pipe has collapsed completely, has significant displacement or cannot be satisfactorily prepared, excavation and replacement may provide the better solution.
Because Dorset Drainage Services undertakes both conventional repair and relining, the repair method can be selected around the actual condition of the drain.
Commercial Applications
No-dig repair can be particularly useful on operational sites where access, traffic movement or finished surfaces make excavation undesirable.
Domestic Drain Relining
No-dig repair can also be particularly useful for drains beneath driveways, patios, gardens, extensions, buildings and finished landscaping. Where appropriate, relining can reduce the amount of surface reinstatement required.

FAQ
Frequently Asked Questions About Drain Re-Lining
Is relining a structural repair?
Yes. The relining process creates a new structural lining inside suitable existing pipework.
Does relining require excavation?
The main advantage is that extensive excavation can often be avoided.
Can you reline pipes underneath a building?
Suitable drainage below buildings can potentially be relined from accessible points.
Can root-damaged drains be relined?
Potentially. Root growth can first be removed before the condition of the pipe is assessed.
Do you survey before relining?
A CCTV inspection is an important way of establishing suitability and planning the repair.
When would excavation be better?
If the pipe has fully collapsed, is badly displaced or cannot be prepared successfully, excavation and replacement may be required.
