HG 3612 - 1.2” Low Profile SDD Board
Our 1.2” Low Profile Stormwater Discharge Delay (SDD) Board is designed with serpentine channels to slow the storm surge on extensive vegetated roofs.
Specific to this product, it:
gathers surplus water within the cells of the panel and passes it from one cell to the next
forces water to travel in a sinuous route, thus lengthening the drainage distance and delaying the discharge to the sewer system
provides vegetation with long-term access to water
allows for the incorporation of a complete array of zone appropriate drought tolerant plantings; in a less than 6” depth assembly
