The Nidaroof product obtained the label "recommended by the professionals of the BTP" Nidaroof is a solution for the management of rainwater in roof terrace, integrated in the complex of water retention of the Wateroof process of Siplast. In urban areas, the storage of rainwater on roofs appears as an economical and relevant alternative solution. Associated with rainwater inlets with limited flow, the nidaroof® product allows to temporarily retain rainwater while keeping the exploitation of the roof terrace. Associated with green roofs, Nidaroof stores rainwater under the substrate and restores it gradually to the plant, thus supporting the recovery of the vegetation in spring and its comfort during dry summer periods. In the case of a roof with slabs on blocks, the nidaroof solution includes a non-woven facing that retains waste and filters the water flowing in the lower part. It avoids the maceration of waste that can generate a source of olfactory nuisance in stagnant water, as well as the proliferation of larvae, mosquitoes or insects.
