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 FW402?

5 reasons engineers specify Mirafi monofilament woven fabric over generic drainage alternatives

Engineered for Pipe Wrap & Subdrain Applications

Precise AOS and high flow rates make FW402 the right choice for subdrain pipe wraps, trench drains, and filtration applications with moderate survivability needs.

Higher Grab Tensile Than Lighter Drainage Fabrics

More grab tensile than FW300 for installation conditions involving angular aggregate and higher compaction pressures.

DOT Specified for Drainage Applications in Multiple States

Mirafi FW402 appears on DOT qualified products lists for drainage fabric applications — simplifying project specification and acceptance.

USA-Made, BABA Eligible

Produced in Georgia — meets Build America / Buy America requirements for federally funded drainage infrastructure.

ASTM-Verified Properties

All key engineering properties are tested and published per ASTM standards — providing the submittal documentation required on public 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
