Woven geotextiles are individual threads (monofilaments, multi-filaments, fibrillated yarns) or slit films and tapes that are actually woven on a loom. Typically, woven geotextile fabrics can be used for stabilization, separation, reinforcement, and erosion control applications. Woven geotextile fabrics strive to provide dimensional stability and deliver superior load distribution. Slit Tape constructed woven geotextiles provide excellent stabilization and separation characteristics ideally for ground reinforcement applications Woven fabrics offer high tensile and puncture strengths. Woven geotextiles typically hold a higher strength to weight ratio in comparison with their non-woven needle-punched geotextiles. In comparison to non-woven geotextiles, woven geotextiles typically maintain slower drainage characteristics due to their smaller pore sizes. Therefore, woven geotextiles are less likely to be applied in engineered areas that require high filtration and drainage characteristics. Woven geotextiles are applied in Transportation Engineering to prevent the intermixing of subgrade soils and subbase materials. By separating the subgrade soil and subbase fill materials, the geotextile preserves the strength characteristics of the aggregate material and also preserves the drainage behaviour. Geotextiles’ high strength property characteristics provide stabilization over soft or poorly drained soils. It also helps to restrict the upward flow of water and finer soil particles into the gravel, which would otherwise drastically reduce the strength of the gravel. The stabilization application of geotextiles acts jointly with the function of separation. The stabilization characteristic of geotextiles is applicable more commonly for saturated and soft subgrade soils. Using geotextile fabrics as a stabilization technique allows unstable subgrade areas to strengthen their bearing capacity, limit any deformation, and decrease any structure settlements. The execution of high strength permeable geotextiles results in increased life of a road and reduced potential repairing costs when used for separation and stabilization applications. Geotextiles have been successfully used in areas associated with high loads, pressures, or traffic such as:

• Rip Rap Erosion Control
• Driveway/Road Stabilization
• Separation of Aggregates
• Railroad Construction
• Erosion Control
• Support Under Seawalls

The fibrillated tape and monofilament combination woven geotextiles are commonly applied to areas needing additional reinforcement and separation. They can be used to reinforce earth structures by means of fill materials. Their high soil to fabric friction coefficient, high tensile strength, and relatively low elongation make them an ideal reinforcement solution.

• Fibrillated tape and monofilament combination woven geotextiles are often used in

high sloped, soft, or poorly drained soils that contain low bearing and shear strength properties. They provide axial strength, excellent drainage properties, and soil stability to desired areas of structure placement. The use of such material reduces construction time, area excavation and fill costs, and offers long-term structure stability.

• They are typically used for Embankments, Dams and Flood Defence, Retention Bunds, Green Walls, Culvert Head
