Drain Patch Lining & Rat Patch Repairs
Patch lining repairs a damaged section of drain from the inside, with no digging. It’s one of the most effective ways to seal a defect that’s letting rats into a property.
When Patch Lining Is Used
Early identification helps prevent larger problems. Common signs include:
Cracks
Cracked or fractured pipe sections
Open Joints
Displaced or open joints
Root Entry
Small root ingress points
Rat Routes
Defects rats are using to get out
Hard Access
Drains under driveways, patios or extensions
A resin-soaked liner is positioned over the defect using an inflatable packer. Once cured, it forms a strong, smooth patch bonded to the pipe.
Because it’s a no-dig repair, there’s no damage to gardens, driveways or floors, and the work is usually completed in a single visit.
How Patch Lining Works
The repair is carried out through existing access points.
The process:
- CCTV survey to locate the defect
- Clean the pipe with drain jetting
- Position the resin patch
- Inflate and cure the liner
- Re-survey to confirm the repair
The finished patch restores a smooth, sealed pipe.
Rat Patch Repairs
A rat patch is a patch liner used to seal the specific defect rats are using.
Typical rat patch locations:
- Displaced joints near the building
- Cracks near rest bends
- Old redundant branch connections
- Damaged sections under extensions
Combined with a rat blocker, it gives strong long-term protection.
Benefits of No-Dig Repair
Patch lining is often quicker and less disruptive than excavation.
Benefits include:
- No digging or reinstatement
- Minimal disruption
- Usually completed in one visit
- Long-lasting sealed repair
Where patch lining isn’t suitable, we’ll recommend an excavation repair.

A no-dig repair where a resin liner is cured inside the pipe over a defect.
Is patch lining permanent?
It’s designed as a long-term structural repair of the damaged section.

Sealing the defect closes the route rats use. A rat blocker can be added for extra protection.
