Embossed Drainage and Water Retention Membrane
GEO GARDEN DUO
The Eurovent® GEO GARDEN DUO drainage and water retention membrane is made of high-density polyethylene (HDPE) with a parallel arrangement of 20 mm high dimples and additional perforations. It is integrated with a PP filter geotextile. The dimples retain water, while excess water is drained away.
Advantages:
- drainage for green roofs
- retains up to 6 l/m² of water
- resistant to compression
Application and Technical Data
Eurovent® GEO GARDEN DUO is used as a horizontal layer in inverted roof and roof garden systems, providing effective drainage of excess rainwater during heavy rainfall. At the same time, the high dimples act as water retention reservoirs, helping to store the water required for plant growth.
The integrated filter geotextile layer prevents soil particles from entering the spaces between the dimples, ensuring efficient and long-lasting operation of the drainage system.

For maximum performance, Eurovent® GEO GARDEN DUO should be used in combination with:
- Eurovent® filtration geotextiles, which protect the drainage and water retention layer against clogging and allow unrestricted water flow,
- Eurovent® garden and surface drainage systems, which drain excess water and work together with the membrane to create stable water retention layers,
- sub-base layers and landscaping aggregates, which, when combined with GEO GARDEN DUO, increase substrate stability beneath paths, terraces and recreational areas,
- Eurovent® vertical and horizontal waterproofing systems, when the membrane is used adjacent to buildings, additionally protecting the structure against moisture and mechanical damage.
