Polyflow® BD Protection and Drainage System is manufactured with a geo-composite of a formed pre-punched impermeable polymeric core covered on both sides with a non-woven filter fabric. Polyflow® BD (Balcony Drain) is a sheet molded drain that establishes predetermined pathways for balcony water management. The fabric allows the water to flow to designated drainage exits. The punched core increases the overall release of water from within the system. Polyflow BD Sheet Molded Drainage is designed for balcony deck applications only. |
