Woven Geotextile Fabric
A Woven Geotextile is made from polypropylene filaments that are woven together to produce a strong fabric with low permeability. This type of geotextile fabric is commonly used for stabilization under subgrades, roads embankments and rip rap. Woven geotextiles are also known as road fabric, driveway fabric, subgrade fabric and stabilization fabric.
Common Applications
Woven geotextiles are found on just about every construction site.
Applications Include:
- Subgrade stabilization
- Erosion control
- Reinforcement
- Separation
- Embankments
- Slope stabilization
- Construction entrances
Silt fence and road fabric are the two most common woven geotextile applications. Woven fabrics are also used for construction entrances, driveways, hardscapes, landscapes and specialty engineering applications.
Types of Woven Geotextiles
Woven geotextile fabrics include woven slit films, medium strength fabrics, and monofilaments. The manufacturing process differs slightly between each fabric in order to produce the desired physical properties.
Woven Slit Films
Woven Slit Film geotextile fabrics are used for stabilization and separation. These fabrics absorb and dissipate tensile force which reduces the ability for soil to deform.
Woven Slit Films include silt fence, road fabric, driveway fabric, construction entrance kits, stabilization fabric and rip rap fabrics.
Stabilization fabrics prevent stone from sinking into the poor soil which could compromise aggregate stability.
Medium Strength Woven Geotextiles
Medium Strength Geotextiles are used on slopes, embankments, roadways, and landfills. These woven geotextiles are produced to support high tensile force and have excellent permittivity. Medium Strength Woven Geotextiles offer subgrade reinforcement and stabilization with increased capacity for water flow.
Monofilaments
Woven Monofilaments are formed with round polypropylene filaments that are woven to various opening sizes. The resulting geotextile fabric has excellent flow, durability and strength. Monofilaments filter soil particles with high permittivity in order to create erosion control stabilization. The high modulus structure of the woven filaments improves the subgrade’s mechanical properties. Monofilaments can also be placed below roadways to separate dissimilar material in order to improve the functional structure.
A Monofilament geotextile fabric can be either calendared or not calendared.
If a Monofilament is calendared, it has undergone an additional heating process that makes it stronger but less permeable than a non-calendared geotextile.
Monofilaments are often specified for bulkheads, jetties, breakwaters, dikes and soils with high water tables.
