SikaRoof® VersiDrain® 30

WATER-RETAINING PLANTING TRAY AND DRAINAGE FOR EXTENSIVE GREEN ROOFS

SikaRoof® VersiDrain® 30 is a lightweight planting tray designed for extensive green roofs and functions both as a water retention layer and a drainage mat. Modules are manufactured from recycled polypropylene (PP) with reservoirs 30 mm deep, providing good water retention capacities, while achieving required drainage capabilities. SikaRoof® VersiDrain® 30 modules interlock with adjacent modules for easy installation and has a smooth base for safe placement directly over the waterproofing membrane.

  • Integrated water reservoir
  • High drainage capacity
  • Trays interlock adjacently for uniform coverage
  • Smooth base protects underlying waterproofing membrane
  • Flexible to conform to curved surfaces
  • Easily cut to size for odd shaped layouts
  • 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 drainage module.

APPLICATION

SikaRoof® VersiDrain® 30 shall be loosely laid and interlocked with adjacent modules connected by proprietary in-built 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 over the modules.
