Mirafi G200N Drainage Composite - 4' x 50' Roll - Solmax
FREE SHIPPING
The Mirafi G-series is a prefabricated drainage composite that relieves water pressure behind walls and structures.
It combines a high-flow drainage core with a bonded nonwoven geotextile, collecting water and carrying it away while filtering out soil. This reduces hydrostatic pressure against retaining walls, foundations, and below-grade surfaces.
The G-series replaces traditional aggregate drainage layers with a thin, easy-to-install sheet, saving space and labor while providing reliable long-term subsurface drainage.

Why Choose Mirafi G200N?
5 reasons engineers specify Mirafi geocomposite drainage over generic alternatives
Higher Flow Capacity Than G100N for Demanding Drainage
Greater transmissivity than G100N for applications requiring higher drainage flow rates or longer drainage paths.
Engineered Flow Capacity Tested Per ASTM Standards
Transmissivity and flow capacity tested and published per ASTM standards — providing the engineering documentation required for acceptance.
Integrated Filter & Core Reduces Installation Complexity
Single-product installation eliminates separate aggregate and filter placement — reducing labor and installation time vs traditional drainage systems.
DOT-Specified for Sheet Drain & Erosion Drain Applications
Mirafi G200N is specified on DOT projects for geocomposite drainage applications including erosion sheet drain and retaining wall drainage.
USA-Made, BABA Eligible
Manufactured in Georgia — qualifies for Build America / Buy America requirements on federally funded drainage infrastructure.
