Green roof stormwater management module CAPTIO®

flat roof

Description
CAPTIO® is a honeycomb-type panel module designed for temporary water retention on waterproofed roof terraces. Manufactured from 100% recycled polypropylene, the product is offered in several heights (main range 30–240 mm and complementary versions 270–510 mm). Modules are pre-assembled and stackable thanks to interlocking features, simplifying installation on roofs.
