Mirafi® FW-Series

TenCate develops and produces materials that function to increase performance, reduce costs and deliver measurable results by working with our customers to provide advanced solutions.

The Difference Mirafi® FW-Series Engineered Filtration Geotextiles Make:

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

Functions

Filtration

The equilibrium soil-to-geotextile system that allows for adequate movement of a liquid across the plane of the geotextile with limited soil loss over the service lifetime of the application.

Erosion Protection

The use of an erosion control blanket (ECB) or turf reinforcement mat (TRM) to protect the soil surface and prevent soil particles from being detached by rainfall, flowing water, or wind.

Separation

The placement of a flexible, porous geotextile between dissimilar materials so that the integrity and intended functions of both materials remain intact or are improved.

Reinforced Soil Slope & Armored Revetment, East Lyme, CT

United States, Connecticut, East Lyme

The challenge was to connect two public beaches separated by armored slopes with an elevated pedestrian and bike path. The trail must also provide protection for a high speed rail line from the severe wave action of the Atlantic Ocean.
