Product Information
Product Specifications
The system consists of siphon drainage boards (polymer-based, profiled protective drainage sheets), HDPE membranes, and heat-bonded geotextiles, combined with siphon drainage channels to form an organized, zero-slope siphon drainage and collection system. Unlike standard dimpled drainage boards, this system utilizes the principle of negative-pressure siphoning to collect and discharge rainwater from roof slabs; it is primarily used for large-scale planted roof decks over underground garages.
