Gutters discharge water into a building predominantly due to joint failure but also due to substrate failure caused by severe corrosion. Gutters can also become overwhelmed during storm conditions.

The long term repair of leaking gutter joints is extremely difficult and most repairs, which consist usually of bandage and bitumen applications, can only be considered as an emergency contingency whilst a more permanent solution is sought, or at best, one which will last for 1 to 3 years until the process needs to be repeated.

Unifold is a gutter lining system that is rigid in use and as the name suggests, is able to fold, using system hinges, allowing access to the gutter cavity and then re-open, to maximise the available space within. It has an exceptional life span, well in excess of 30 years and is guaranteed for a period of 20 years including the installation.

Unifold is manufactured from an EPDM membrane that is pressure bonded to galvanized and coated steel substrate. During this process the hinges are formed, which are the essence of the system’s unique flexibility. They provide the ability to enter the most difficult of gutter cavities, maximising the available space.
