HG 3623 - 2.3” Sloped DR Board

Our 2.3” Sloped Drainage / Retention (DR) Board is designed for drainage, slippage prevention, and water storage on extensive vegetated roofs with a slope of up to 35 degrees.

Specific to this product, it:

is a waffled EPS panel that retains water within pockets on the upper side, making water available to vegetation

has good water storage functionality due to the cascade- like overflow of overlapping chambers

permanently protects against slippage of the vegetated roof by filling the storage chambers with substrate

channels surplus water through its bottom-sided canal system for secure drainage

allows for the incorporation of a complete array of zone appropriate drought tolerant plantings; in a less than 6” depth assembly
