DELTA®-FLORAXX - Beständige Gründach-Noppenbahn mit Wasserspeicher ohne integriertes Geotextil.


  • Used as an efficient structural drainage layer in walkable inverted roofs paved with stones or slabs, the innovative DELTA®-FLORAXX dimpled sheet acts as a protection and seepage layer which permits water to drain away freely.
  • Breathable because of the perforation which permits air to circulate, the sheet prevents the formation of a coherent film of water on the waterproofing.
  • Thanks to its robust octagonal dimples additionally reinforced by ribs, its compressive strength is as high as 200kN/m².
