Description
The SOPRARETENTIO MODULE is a honeycomb structure, made from polypropylene, with a non-woven polypropylene geotextileheat-welded to the top.
UNITS PER SKID: 84
Material Use:
The SOPRARETENTIO MODULE is a specialized drainage and water retention component designed for use in vegetative roofing systems, including green roofs and blue roofs. It serves as a water retention layer that helps manage stormwater while supporting plant growth and maintaining roof system integrity.
System Components:
The SOPRARETENTIO MODULE is composed of a lightweight polypropylene honeycomb core structure, which provides high void space for water retention and drainage. A non-woven polypropylene geotextile is heat-welded to the top of the module, acting as a filtration layer to prevent soil or growing media from clogging the drainage core. This module is typically used in conjunction with other SOPRANATURE vegetative roofing components, such as root barriers, filter fabrics, growing media, and vegetation layers.
Applications:
This product is intended for use in SOPRANATURE vegetative roof assemblies, including:
- Green roofs (extensive and intensive)
- Blue roofs (designed for temporary water storage)
- Plaza decks with integrated landscaping
- Modular green roof systems
Application Details:
Installation involves placing the SOPRARETENTIO MODULES with the geotextile side facing upward. Modules should be laid side by side, ensuring that the geotextile overlaps are positioned on top of adjacent modules to maintain continuity of the filtration layer. The product is modular and easy to handle, making it suitable for both new construction and retrofit applications.

- Geotextile Properties:
- Thickness: 0.77 mm (30 mils)
- Flow Rate: 1.47 gal US/s/ft² (22.6 L/s/m²) under 50 mm hydraulic head
- Grab Breaking Load: 874/508 N (196/114 lbf)
- Elongation at Break: 37% (MD) / 88% (XD)
- Puncture Resistance: 426 N (95.8 lbf)
Environmental and Installation Considerations:
- The SOPRARETENTIO MODULE is made of polypropylene, which is resistant to rot, mold, and most chemicals, making it suitable for long-term use in vegetative roof environments.
- It is not a liquid-applied product and therefore does not have pot life, curing time, or temperature/humidity limitations during installation.
- The product is UV-resistant due to the geotextile layer, but it is typically installed beneath soil or vegetation, which provides additional UV protection.
- No adhesives or primers are required for installation.
- This product is a complementary component in SOPREMA’s SOPRANATURE vegetative roofing systems and should be used in conjunction with other compatible SOPREMA products for optimal performance.
This product is ideal for sustainable building projects seeking to manage stormwater, reduce urban heat island effects, and support rooftop vegetation.
