Woven Monofilament Filtration

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 FW404?

5 reasons engineers specify Mirafi monofilament woven fabric over generic alternatives

Heavy-Duty Monofilament for Class 1 Railroad & Aggressive Drainage

High grab tensile and puncture resistance survives installation under large stone fills, ballast, and aggressive drainage trench conditions.

AREMA-Compliant for Railroad Track Subsurface Drainage

Meets AREMA geotextile requirements for Class 1 railroad drainage applications — one of few fabrics that satisfies this demanding specification by name.

DOT Pre-Approved, ASTM-Tested

Mirafi FW404 appears on state DOT qualified products lists and has published ASTM grab tensile, AOS, and permittivity data for project submittals.

USA-Made, BABA Eligible

Produced in Georgia — qualifies for Build America / Buy America requirements on federally funded railroad and highway projects.

PRODUCT SUMMARY

  • Engineered Filtration: Resists clogging while maintaining flow rates in high gradient and dynamic flow conditions.
  • Durability: High survivability rating in aggressive installation and loading conditions along with excellent resistance to chemicals in aggressive environments.
  • Soil Interaction: Superior soil confinement resulting in greater load distribution.
  • Unique Constructions: Manufactured with highly UV stabilized multifilament fibers which provide uniform opening size (AOS) while maintaining high long-term flow rates. Mirafi ® FW-Series geotextiles are manufactured with specialized processes to produce unique physical and hydraulic properties not possible with standard geotextiles, woven or nonwoven.
  • Seams: Panels can be sewn together in the factory or field, providing cross-roll direction strength to facilitate installation
