SikaRoof® VersiDrain® BG®

WATER ATTENUATING PLANTING TRAY MODULES FOR EXTENSIVE GREEN ROOFS

SikaRoof® VersiDrain® BG® is a lightweight planting tray designed for extensive blue green roofs and functions as a water retaining tray, water attenuation tray, and a drainage mat. Modules are manufactured from recycled polypropylene (PP), and consist of three layers: a planting layer, an irrigation reservoir area, and a stormwater attenuation layer. SikaRoof® VersiDrain® BG® interlock with adjacent modules for easy installation and has a smooth base for safe placement directly over the waterproofing membrane. Its internal irrigation reservoir promotes plant sustainability and its stormwater attenuation layer collects and slowly releases at-source stormwater to mititgate overburdening of drainage infrastructures amidst our current crisis.

  • Integrated water reservoir
  • Integrated water attenuation
  • Trays interlock adjacently for uniform coverage
  • Smooth base protects underlying waterproofing membrane
  • Resistant to biological attack by moulds and algae
  • Chemically resistant to acids, alkalis, oils and soil chemicals
  • Operates within a wide service temperature range

Application

Application steps

SUBSTRATE PREPARATION

Clean and sound surface shall have at least a wood float finish. All holes, joints, and cracks and honeycombs in concrete or masonry surfaces shall be filled with an approved grout and allowed to cure. High spots in concrete or masonry surfaces shall be cut off or ground down to prevent damage/puncture to the water retention planting tray module.

APPLICATION

SikaRoof® VersiDrain® BG® shall be loosely laid and interlocked with adjacent modules connected by proprietary clips to form a continuous water retention and drainage layer without any mechanical fixing either on top of the waterproofing membrane or on top of the concrete surface. The installed water retention and drainage modules would then be covered with an approved or Sika® geotextile filter fabric before pouring the planting media into the modules.
