The System
OASIS is Le Prieuré’s patented solution for optimizing water resources and landscaping your roof gardens.
HYDROSTOCK tanks are connected to each other to form a uniform water reservoir on the roof. The water stored in the tanks (52 L/m²) rises by capillary action to the substrate, or evaporates.
A flow limiter is located in each tank zone (approximately every 80 tanks) to allow water that has not been evapotranspired or consumed by the plants to be drained off, at a micro-flow rate of up to 0.5 L/s/ha.
The Modulo multimodal plate can accommodate any type of layout: vegetated areas, trees, battens and separating elements, cladding, up to 2 tons/m² without deformation. Without this plate, OASIS is also compatible with HYDROPACK ( OASIS PACK solution).
For use on all types of roofs, with a maximum pitch of 10%.
