Description
SOPRARETENTIO BOARD is a drainage board with water retention properties made from polyester.
UNITS PER SKID: 70
Material Use:
SOPRARETENTIO BOARD is a multifunctional drainage and water retention panel designed for use in green roofing systems, plaza decks, and other flat or sloped roofing applications requiring water management. It serves to retain a specific volume of water for vegetative systems while also facilitating the drainage of excess water to designated outlets. Additionally, it can act as a protection board over waterproofing membranes, enhancing the durability of the underlying system.
System Components:
SOPRARETENTIO BOARD is typically used as part of a vegetative roofing system (SOPRANATURE) and is compatible with SOPREMA waterproofing membranes. It is installed directly over the waterproofing layer and may be used in conjunction with other SOPRANATURE components such as filter fabrics, root barriers, and growing media. While it does not require primers or coatings, it is a complementary component in a larger green roof assembly.
Applications:
- Green roofs (extensive and intensive systems)
- Plaza decks with water management requirements
- Flat or sloped roofs requiring water retention and drainage
- Protective layer over waterproofing membranes
Application Details:
SOPRARETENTIO BOARD is installed side by side directly on the surface of the roof or deck, ensuring no gaps between the panels. The boards are laid flat and do not require mechanical fastening. Installation should be performed in accordance with SOPREMA guidelines and under the supervision of a qualified representative when necessary.

- Puncture Resistance: 220 N (49.5 lbf)
- Flow Rate at 20 kPa (Hydraulic gradient 1.00): 0.21 L/s/m (0.017 gal US/min/ft)
Environmental and Installation Considerations:
- SOPRARETENTIO BOARD is a passive component and does not have specific temperature or humidity limitations for installation, but it should be installed in dry conditions to ensure proper placement and performance.
- It is not UV-stable and should be covered with soil, vegetation, or other protective layers as part of the green roof system.
- No pot life, curing time, or full cure time is applicable, as this is a prefabricated board product.
SOPRARETENTIO BOARD is an essential component in SOPREMA’s SOPRANATURE vegetative roofing systems, offering both water retention and drainage capabilities while protecting the waterproofing membrane and supporting sustainable building practices.
