Green roof drainage

A key advantage of both extensive and intensive green roofs is their ability to store rainwater. But depending on the structure of the substrate, even these capacities will reach their limit sooner or later. Especially in wetter periods or in the case of heavy rainfall, these green spaces require extra support to collect and subsequently channel away accumulating rainwater. 

This is where our expertise and corresponding solutions come in. We offer a range of high-performance components for green roof dewatering. Our integrated system for green roofs, for instance, already comprises essential elements such as drainage and water storage mats. Moreover, gravel stops, which similarly form part of this system, not only frame green spaces and separate them from fills, they also ensure that excess water is channelled away in a controlled manner. Beyond the integrated green roof system, our range of products encompasses both dewatering and drainage channels as well as branch channels, inspection shafts and gullies, all of which reliably dewater roof surfaces and protect their structural fabric.
