General Specs

General Specs

Poly Wall® Arroyo™ Drain Board is a sheet molded drain that establishes predetermined pathways for below-grade water management. The fabric allows water to pass into the drain core while restricting the movement of soil particles which might clog the core. The core allows the water to flow to designated drainage exits. Arroyo™ Drain Board Sheet Molded Drainage is designed for vertical applications and is suitable as protective layers for Poly Wall® waterproofing membranes.
