Patch lining Repairs are a highly cost-effective remediation solution offering a structural and watertight localised drain repair.
Using a robotic CCTV Camera locate the precise area with the defect being in the centre of the patch.
Once the correct location is found a fibreglass matting is then impregnated with a silicate resin and attached to a large rubber tube with sealed ends. This with the attached patch is manoeuvred into position and then inflated following a set procedure to the required pressure.
Following a monitored process, the inflation results in the patch being calibrated against the existing pipe work, to form the watertight localised patch repair.
