HYDROPACK®, the patented, innovative tray system for green roofs, is one the best solutions for creating a living, breathing green roof and the optimal storm water management tool. With more than 5 million square feet installed on over 1,500 rooftops, HYDROPACK® is one of the most widely used tray systems in existence.
PROVEN in many climates
Patented in 2000, HYDROPACK® was the first green roof tray system to be launched in Europe.
HYDROPACK® has widely proven its performance across a wide range of climate: Mediterranean, humid subtropical, humid continental, semiarid steppe, marine west coast...

"All in One" tray
HYDROPACK® is the only green roof module designed with all the essential layers of a successful green roof system.
It incorporates a strong interlocking system that mitigates wind uplift; the vegetation is fully grown the day of the installation; the growing media is FLL compliant; a filter fabric retains the growth media within the tray to limit soil erosion, drainage holes have a clearance above the membrane to limit stagnant water from coming back into the tray if the roof slope is < 2%, mineral drainage are placed at the bottom of the tray to provide anchoring for the roots; optimal water reserves are designed to increase the drought tolerance of the plants.
HYDROPACK® is part of the Best Management Practices for Stormwater runoff mitigation. Thanks to its water reservoirs and innovative design, HYDROPACK® retains an optimal volume of Stormwater and significantly decreases runoff. Our research show that compared to some 4” built-up systems, HYDROPACK® retains a great deal more water. We can provide you runoff data using HYDROPACK® RUNOFF TOOL developed in partnership with universities. HYDROPACK® can retain up to 100% of precipitation depending on the amount of water and the previous rain events.
