The area to be lined is measured and then the material is cut to size. Then the resin is poured into the material, this is called "wetting out". The liner is then dragged into the drain.
The calibration hose, a large air bag is then inserted into the liner and inflated. This forms the liner to the drain, then it takes time to "cure" i.e. to set. This curing can be effected by temperature and can range from 1 to 6 hours.
All the lining installations are then re surveyed to ensure that they have take successfully.
Our lining is compliant to WRC, water Authority regulations and standards.
