HG 3651 - 1.1” Blue Roof SDD Board

Our 1.1” Blue Roof Stormwater Discharge Delay (SDD) Board integrates with raised roof drains to provide water storage and stormwater discharge delay.

Specific to this product, it:

is a lightweight, sub-surface structural drainage module used where a high capture and discharge rate of water and high compressive strength is required

has 62% surface void area with 95% internal void volume, allowing for a high compressive strength system with a large water retention capacity

significantly reduces daily irrigation needs

is designed to withstand loads imposed by mechanical equipment such as bob-cats

is unaffected by molds and algae and has good resistance to oils, acids, alkalis and bitumen

is available in a flexible version, able to conform to curved surfaces
