Mirafi® Filterweave Woven Geotextiles for Erosion Control and Filtration
DX2® offers a wide range of woven geotextiles for erosion control and filtration applications. These geotextiles are cost-effective erosion control elements which improve and enhance modern construction techniques in a variety of civil engineering applications.Product Description
Mirafi® Filterweave Geotextiles are woven fabrics of monofilament and multifilament yarn construction which are highly UV stabilized. Filterweave Geotextiles have high strengths for durability and survivability; consistent, measurable pore sizes; and high percent open area for long-term clogging resistance and high flow rates. Filterweave Geotextiles are manufactured with highly specialized processes to produce unique physical and hydraulic properties not possible with standard geotextiles, woven or nonwoven.
Features and Benefits
Mirafi® Filterweave Geotextiles offer unique features and benefits over traditional filtration and drainage fabrics. Some of the advantages include:
- Resists clogging while maintaining flow rate in high gradient and dynamic flow conditions;
- High survivability rating in aggressive installation and loading conditions such as back dumping of large rip rap or underwater placement;
- Resistant to chemicals in aggressive landfill environments;
- Highly uniform opening size (AOS);
- Maintains high long-term flow rates;
- Exhibits high percent open area.
- Flexible manufacturing allows custom fabric production to meet site specific soil conditions. Additionally, Filterweave Geotextiles are capable of being fabricated into customized panels.
Applications
Mirafi® Filterweave Geotextiles are designed for long-term performance in problematic soil or site conditions to ensure clogging resistance and soil retention in erosion control and subsurface drainage applications. Typical applications include:
- Underneath rip rap or concrete revetment systems along inland waterways and coastal shorelines;
- Underneath armor systems;
- Protecting spillways and embankment dams from overtopping flow;
- Encapsulating cut-off drains and collection systems surrounding landfills, within dams, and adjacent to roadways and other critical structures;
- Encapsulating leachate collection systems under landfills while maintaining long-term clogging resistance;
- Encapsulating edge drains for critical structures in problematic soils.
