Unidam System

by Ampteam

The system comprises a series of blade-like dams manufactured from materials sympathetic to the original roof. They are fitted along the entire roof slope to the rib of the roof sheet but avoiding any roof lights and roof protrusions, and at right angles to the down slope. The rear of the dam blade is profiled to match the roof sheet but providing a small controlled gap between the roof sheet and the blade edge. This gap will allow light to medium rainfall to pass beneath the blade and into the gutter in a normal way. As rainfall intensifies during a heavy storm and it builds in speed and depth as it travels down-slope the blades create mini dams arresting the excess water, de-energising its speed and containing its volume. The gap beneath the blade will allow water to discharge in a controlled manner and in amounts that allow gutters and outlets to perform, thereby preventing any overflow into the building.
