2. Product range “nature”
Water storage and drainage elements for roof gardens
Water storage capacity is an important consideration when designing roof gardens. ISO-DRAIN nature sheets offer storage capacities of 6 l/m² for extensive planting and up to 24 l/m² for intensive planting. Perforations support drainage, and some versions come with a laminated filter geotextile. Sheets with octagonal dimples are available for applications that require particularly high compressive strength.

Drainage sheets for paths and vehicular areas
Depending on the version, ISO-DRAIN nature sheets can provide horizontal or vertical drainage. They can be used for horizontal drainage beneath terraces, paths and gravel surfaces. Vapour-permeable versions are available for inverted roofs. For natural stone, concrete pavers and slabs laid in drainage mortar or single-size aggregate mortar, sheets are available with a laminated plastic mesh and optional perforations.
