Woven geotextiles are made by interlacing two or more sets of yarns or fibers. This family of geotextile fabrics varies widely in both strength and flow rate, from very low with slit tapes to extremely high in the advanced options, such as the TenCate Mirafi RSi materials. Woven geotextiles provide filtration and separation, but this is typically secondary to their reinforcement confinement functions. The ability of a woven geotextile to provide effective reinforcement, as is important in subgrade stabilization applications, is closely tied to a high modulus of elasticity, or the ability to resist forces with minimal deformation. The standard test that best reflects this is the Tensile Strength at 2% Strain (ASTM D4595). Flow rate is also a major factor, as allowing the movement of water away from a pavement section contributes to pavement life.

- INDOT standard materials/common public works uses: Geotextile for riprap and revetment, geotextile for underdrains and drainage, and geotextiles for pavement and subgrade stabilization
- Advanced materials may be used in foundation design to decrease the size of spread footings or crane pads
- Slit tapes are used for silt fence and to limit flows in some applications, due to their low flow rate
FEATURES AND BENEFITS:
- Wide variety of materials available
- TenCate Mirafi RSi-Series materials provide separation, filtration, confinement, and reinforcement for a quick, effective solution to soft subgrades/bridging soft soils
