A CCTV drain survey is the first step to an accurate repair plan. The next question is almost always the same: do we have to dig the garden up? Modern no-dig techniques can restore a defective drain from the inside, with no excavation and minimal disruption.
When No-Dig Repairs Work
- The pipe is structurally intact enough to accept a liner.
- The defect is the right kind – cracks, fractures, displaced joints, root ingress points.
- There are usable access points at either end.
- The pipe diameter and material are within the range the lining system supports.
When Excavation Is Still Needed
- The pipe has collapsed.
- A long section of pipe is structurally failed.
- The defect is at a connection or junction the liner cannot bridge.
- The pipe is too deformed for the liner to follow.
How A CIPP Liner Is Installed
- The drain is cleaned and prepared internally.
- A flexible liner, impregnated with resin, is positioned at the access point.
- The liner is inverted or pulled into position so it lies snugly against the inside of the existing pipe.
- The liner is cured to harden the resin.
- A final CCTV inspection confirms the liner is correctly seated.
How Long Does A No-Dig Repair Last?
A well-installed CIPP liner has a design life comparable to a new pipe – typically several decades. A 50-year design life is widely cited in the industry.
Comparing Cost
When you include the cost of reinstating gardens, driveways and landscaping, no-dig is usually significantly cheaper and far less disruptive.
