DELTA®-FLORAXX - Garden Roof Applications

DELTA®-FLORAXX DELTA®-FLORAXX provides a high water retention capacity combined with outstanding drainage characteristics, and is an ideal and sustainable component in garden roof designs.

Properties

DELTA®-FLORAXX is a perforated drainage board specifically designed for use in garden roof assemblies. The product features large, 20 mm high dimples with and octagon shape for outstanding compressive strength. Due to its high water retention capacity and its ability to effectively drain away surplus water this special membrane is ideal for use in extensive or intensive rooftop gardens.
DELTA®-FLORAXX is made from 60% recycled HDPE and 40% virgin HDPE.

Material

Studded membrane made of special, high-density polyethylene. Drains surplus water effectively through large perforations between the 20 mm high octagon-shape dimples. This environmentally friendly product is rot-proof in contact with soil.

Application

DELTA®-FLORAXX retains rainwater in its high capacity dimples - an important safety factor for the plants on any garden roof. Any surplus-water can effectively drain away through the perforations and the open channel system under the dimple sheet.

DELTA®-FLORAXX is easily installed on top of a root-proof waterproofing system.
