Indiana INDOT - 918.02 (B) - Underdrains & Drainage Fabric - Type 1B - 15' x 300' Roll - FW402
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.
