Duradrain is a Combined Kerb & Drainage (CKD) system manufactured from a hydraulically efficient material with a large volume of useable channel providing faster flows and large outputs. The range is similar to traditional CKD in terms of function, dimension, profile and transition. Please see technical literature and product downloads for more information.
Combined kerb and drainage systems collect run-off continually and quickly which helps extend the life of a project and improve the conditions for users and their safety, particularly in Highways. Unlike the traditional kerb and gully method where flows compound on the surface, the collected run-off is contained and driven to outlet hidden within the channel body. As the kerb-lines are traditionally set at a low point, the levels on site can be simplified using one-directional cross-fall/camber to deliver surface water to the kerb-side.
