An external drainage membrane with reservoir capabilities for green roofs and buried roofs. A high drainage capacity makes it ideal for various waterproofing projects.

Delta Floraxx Top External Drainage Membrane  

The Delta Floraxx Top is a drainage and reservoir membrane for external waterproofing systems. It combines water storage, effective drainage and filtration in one simple sheet.

With the Floraxx Top, groundwater is quickly drained away. The geotextile layer serves as a filter for debris and particles. Its unique octagonal studs have excellent compressive strength as well as a high water storage capacity, ideal for green and buried roofs. 

Delta Floraxx is manufactured from High Density Polyethylene (HDPE), making it resistant to chemical erosion. The sheet’s protective layer conforms to FLL green roof guidance. 

Available in a 2m x 10m roll. 

Delta Floraxx Drainage Top: A Three-In-One Solution for Underground Structures

The Delta drainage top is suitable for a variety of projects, including:

  • Green roofs
  • Buried roofs
  • Podium decks
  • Basement blue roof applications
  • Civil engineering projects

Installing Delta Floraxx Top

Delta Floraxx is easy to roll out and removes the need to lay multiple sheets on top of each other, making it a highly convenient drainage solution. 

To join sheets you can simply over lap one - two rows of studs and join with Delta Tape or Delta Than.  When the external drainage sheets are joined together, you should have a continuous layer that’s unlikely to slip, shift or flap about in the wind. 

Thanks to its integrated filtration layer, soil or substrate can be placed directly on top of it, ready to begin planting your green roof.
