Drain Relining Using Inversion Lining Technology
If you’ve been told that your drain is cracked, fractured, leaking or suffering from root ingress, you may assume that the only solution is excavation. Traditionally this would have been the case, often involving digging up driveways, patios, gardens and even parts of buildings to access the damaged pipework.
Thanks to modern inversion drain lining technology, many drainage defects can now be repaired without excavation, reducing disruption, saving time and often lowering repair costs.
At The Drain Unblocking Company, we use modern inversion lining systems to restore damaged drains throughout Manchester, Stockport, Cheadle, Bramhall, Wilmslow and the surrounding areas.
What Is Drain Relining?
Drain relining is a trenchless repair method that creates a new pipe within the existing damaged pipe.
A specially designed liner saturated with resin is inserted into the drain and positioned over the damaged section. Once in place, the liner is inflated using inversion technology, forcing it tightly against the existing pipe walls.
As the resin cures, it forms a strong structural pipe within the original drain, effectively sealing cracks, fractures, displaced joints and minor defects.
The result is a long-lasting repair without the need for excavation.
What Is Inversion Drain Lining?
Inversion lining is one of the most advanced methods of drain rehabilitation currently available.
Unlike traditional pull-in liners, inversion systems use air pressure to turn the liner inside out as it travels through the pipe. This process ensures:
- Consistent liner placement
- Excellent adhesion to the host pipe
- Full structural support
- Reduced risk of wrinkles
- Faster installation times
The technique allows repairs to be completed from existing access points such as manholes, inspection chambers and rodding eyes.
Common Problems That Can Be Repaired With Drain Relining
Inversion lining is suitable for many common drainage defects, including:
- Cracked drains
- Fractured pipework
- Root ingress
- Open joints
- Minor pipe deformation
- Leaking drains
- Groundwater infiltration
- Corrosion in older pipe systems
Following a CCTV drainage survey, our engineers can determine whether the pipework is suitable for relining or if excavation is required.
Benefits of Inversion Drain Lining
No Excavation Required
One of the biggest advantages is avoiding unnecessary digging. Driveways, patios, landscaping and internal floors can often remain untouched.
Faster Installation
Most residential lining projects can be completed within a single day.
Long Service Life
Modern liners are designed to provide decades of service when installed correctly.
Cost Effective
Avoiding excavation can significantly reduce labour, reinstatement and landscaping costs.
Environmentally Friendly
Less excavation means less waste, fewer materials and reduced disruption to the surrounding area.
The Drain Relining Process
1. CCTV Survey
We begin with a detailed CCTV inspection to identify defects and confirm the drain is suitable for lining.
2. Drain Cleaning
The pipe is thoroughly cleaned using high-pressure water jetting to remove debris, scale, roots and deposits.
3. Liner Preparation
A specialist liner is impregnated with resin and prepared for installation.
4. Inversion Installation
The liner is inverted into the pipe using controlled air pressure.
5. Curing
The resin hardens, creating a durable pipe within the existing drain.
6. Final CCTV Inspection
A post-installation CCTV survey confirms the repair has been completed successfully.
When Is Excavation Still Required?
Although inversion lining can repair many drainage defects, excavation may still be necessary if:
- The pipe has fully collapsed
- There are significant structural failures
- Severe deformation is present
- Access cannot be obtained
- The damaged section is inaccessible for lining
A CCTV survey will identify the most suitable repair method.
Is Drain Relining Covered by Insurance?
In some circumstances, drainage repairs may be covered by buildings insurance, particularly where damage has occurred as a result of:
- Ground movement
- Subsidence
- Sudden collapse
- Tree root intrusion
Insurance requirements vary, so we always recommend checking with your provider.
