Mirafi FW300 Geotextile Fabric - 12.5' x 300' Roll - Solmax
FREE SHIPPING
The Mirafi FW-series is a woven monofilament geotextile designed for high-flow filtration and drainage.
Woven from monofilament yarns, these fabrics keep large open pathways for water while filtering soil, giving them excellent flow and clog resistance in wet, fine-grained conditions. They are specified for subsurface drainage, riprap bedding, and permanent erosion control.
Where standard wovens would blind or clog, the FW-series maintains permeability over the long term, making it the choice for drainage-critical and high-sediment environments.

Why Choose Mirafi FW300?
5 reasons engineers specify Mirafi monofilament woven fabric over generic drainage geotextiles
Monofilament Construction for High-Flow Drainage
Larger AOS openings in monofilament woven construction allow high hydraulic flow rates for pipe wrap, drainage trench, and underdrain applications.
Superior Hydraulic Conductivity vs Nonwovens
Where flow capacity is the priority, FW300's monofilament structure outperforms needle-punched nonwovens in hydraulic conductivity per unit area.
DOT Specified for Drainage Fabric Applications
Mirafi FW300 is pre-approved for drainage fabric applications on DOT projects — providing straightforward project acceptance.
USA-Made, BABA Eligible
Manufactured in Georgia — qualifying for Build America / Buy America requirements on federally funded drainage projects.
Published ASTM Test Data for Engineering Submittals
AOS, permittivity, grab tensile, and burst strength are published per ASTM standards — providing the documentation package engineers require.
