Although non-woven geotextile has a lower tensile strength than the woven type, it still offers great strength, durability and excellent drainage properties. Non-woven geotextile is a felt-like fabric made by thermally bonding polypropylene or a mixture of polypropylene and polyester fibres and then finishing using needle punching, calendering and other methods. This type of geotextile fabric is easier to cut, has a high water permeability rate and does not lose strength over time, in the same way as the woven fabric does, when used below ground. This makes it ideal for use beneath driveways and roads and in land and stormwater drainage systems, where long-term ground stabilisation and filtration is required.
Nonwoven Geotextiles are needle punched to form a strong fabric that retains its dimensional stability and is resistant to damage from construction stresses.Nonwoven Geotextiles are available in varying strengths and thicknesses to ensure appropriate material selection for your project. Custom roll sizes are also available.
Nonwoven Geotextiles have a wide range of applications in civil environmental engineering and construction projects. Their uses include:
1. Filtration of soils in drainage applications by retaining soil particles while allowing for the free flow of water
2. Separation and stabilization in road and railway construction
3. Prevention of soil movement in erosion control measures
4. Cushioning and protection in many containment projects
