SikaRoof® VersiCell® Flex

SUB-SURFACE DRAINAGE MODULES FOR DRAINAGE OF LANDSCAPE FEATURES

SikaRoof® VersiCell® Flex is a lightweight, high-strength drainage module manufactured from recycled polypropylene (PP) with cells 30 mm high, providing large internal void volumes for increased drainage discharge capacity. The module is flexible to accommodate curvatures of structural designs. SikaRoof® VersiCell® Flex forms a hollow space between the structural element and the planting media, providing excellent drainage to prevent flooding of the landscape features.

  • Flexible to conform with structural design
  • High compressive strength
  • Smooth base, safe for direct laying onto waterproofing
  • Interlocking modular design ensuring continuous drainage
  • High discharge capacity
  • Small surface perforations to prevent sagging of geotextile
  • 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 steps

SUBSTRATE QUALITY

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