Our DELTA® protection and drainage sheets have been specially developed to drain flat roofs and to protect their waterproofing. Their high drainage capacity enables them to convey surplus water reliably towards the roof gutter, while their high compressive strength serves to protect the waterproofing optimally. Their outstanding characteristics are permanent filtration stability and longevity. All this makes them a sustainable alternative for flat roofs of any kind. Our compression-resistant drainage sheets not only eliminate waterlogging and silting, they also withstand mechanical loads.
