Miradrain 9800: Henry Drainboard 4′ x 50′

MiraDRAIN 9800 is a high-strength drainage composite made to move water away from walls, decks, planters, and other below-grade or horizontal surfaces. It uses a molded polypropylene core with a heavy nonwoven filter fabric bonded to the dimples, which helps keep soil from clogging the drainage path while still allowing water to flow through. This helps relieve hydrostatic pressure and protects the waterproofing system underneath.

It is built for high-flow, high-compressive-strength drainage jobs where you need reliable performance under backfill and long-term soil pressure. The flat side sits tight against the wall or deck, which makes it a good fit for foundation walls, underslab work, plaza decks, planters, and green roof applications. It can also serve as a protection course over CCW waterproofing membranes.

MiraDRAIN 9800 is lightweight, easy to cut, and easier to install than gravel-based drainage systems. It offers high flow capacity, strong filtration, and durable support while helping reduce labor and material handling. It comes in 4′ x 50′ rolls and is designed for both vertical and horizontal drainage applications where long-term water management matters.
