Drain patch repair addresses an isolated defect without lining the complete run. We use it where the damage can be reached and the surrounding pipe is suitable. The survey establishes whether the problem is truly local before a short repair is selected.
Drain Patch Repair
Local drain patch repair for isolated defects where the surrounding pipe remains suitable.

Positioning a sectional repair
The patch needs accurate positioning over the defect within a suitably prepared pipe.
Patch length and surrounding pipe
Sound contact areas beyond the damage are essential to the selected sectional repair system.
Installing a local drain patch
A typical patch system carries resin-impregnated reinforcement on an inflatable packer. It is positioned across the defect and held against the prepared pipe while the resin cures. Diameter, bends and nearby branches affect suitability, and the chosen system determines the installation pressure and cure procedure.

Repair length and surrounding pipe
A patch has a finite length and needs appropriate contact with sound pipe around the defect. It does not repair every joint upstream or downstream. Afterwards, we inspect the patch position and note any other defects that may need monitoring, another patch or a longer liner.
Branches and junctions near the repair
The patch must cover the defect without obstructing an adjoining connection. A nearby branch, bend or diameter change can require a different patch position or dedicated junction treatment.
Drain Patch Repair: common questions
Can a patch fix one leaking joint?
A suitable joint can be repaired locally where access and surrounding pipe condition permit it.
Does a patch repair the whole drain?
A patch covers a defined length; adjoining pipework is not renewed automatically.
When is a longer liner more suitable?
A longer liner may be justified where defects are distributed along an otherwise suitable run.
Can a patch obstruct a branch opening?
An unsuitable position could do so. Branch locations must be considered before selecting the repair.
Does patching correct a poor fall?
It repairs a defined defect, but generally does not change the existing drain levels.
