Fields of application
In green roofs Delta - Floraxx Top is ideal for herbaceous covers that
are required to survive for prolonged periods without irrigation.
Thanks to its robust octagonal dimples, additionally reinforced
by ribs, the sheet will safely support heavy, evenly distributed loads.
Intensive roof gardens with trees and bushes which have deep
root systems require more sedum and water. The dimpled sheet
therefore needs to have an extremely high compressive strength in
order to deal with the weight.
- Planters
- Intensive green roofs (where water storage is required for larger plant types)
- Extensive roof gardens
Features
- Retains 7 litres of water per m2
- High drainage capacity and protection to waterproofing
- Extremely high compressive strength of 200 kN/m2
- Fast and economical installation
- Long life expectancy
- Root resistant
Installation
- The sealed surface must be thoroughly cleaned, so that after installation of the drainage layer no damage can occur to the waterproofing. The waterproofing must be root resistant or protected by a root barrier. A protective separating layer is laid on the waterproofing.
- The dimple sheeting is simply rolled out on the underlayer. Dimples facing the surface and cups facing up. The sheeting can be cut with a blade.
- To extend a sheet, lay two rows of dimples together.
- Install the sheets step by step

Drainage Lengths
Because of its disproportionately high drainage capacity,
Delta Floraxx is suitable for great drainage lengths and, by the same token, for roofs with an unusually low gradient.
