HG 3624 - 2.4” Intensive SDD Board
Our 2.4” Intensive Stormwater Discharge Delay (SDD) Board is designed with serpentine channels to slow the storm surge on semi-intensive 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 perennials and ornamental grasses; in a 6-12” depth assembly
