Drainage and filtration layer

The drainage and filtration layer is designed to drain excess water quickly and effectively. The green roof drainage layer is required on roofs up to a 5° slope; drainage is not used on roofs with a higher slope. For drainage, loop mats, bucket mats or gravel of the appropriate fraction are used. A geotextile, i.e. a filter, is placed on the drainage, which is designed to prevent the substrate from clogging the drainage.
