Leaking gutters cost millions of pounds every year in maintenance costs. 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.
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 a 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.
A solution to leaking joints is to line the existing gutter, however, effective access is a common problem due to roof sheet overhang and other obstructions, leading to a reduction in gutter size with the resultant loss of valuable water capacity. Often continuous flexible lining systems are chosen as they are perceived to have no joints and they are sometimes able to reach the extremes of the existing gutter profile.
They are, however, very prone to expansion, contraction and retention problems leading to instability and ultimate failure and these systems often cannot cope correctly with existing gutter fabrication. Any gutter lining system must be able to correctly address the problems with which it is faced and be able to provide a true, quality assured solution for all the variations of gutter design, both past and present.
What is required is a system that is correctly designed and engineered that will maximise the available space within the existing gutter cavity, will remain rigid and stable in service, will offer an exceptional life span and be guaranteed not to leak.
Unifold is a gutter lining system that is rigid in use, 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.
