Non-woven geotextiles are needle-punched to provide excellent strength and hydraulic characteristics necessary for filtration, separation, protection against damage, ground stabilization, drainage, and erosion control applications. Needle punched nonwoven is manufactured by mechanically orienting and interlocking polypropylene fibers of a carded web. With the combination of drafting and heat, non-woven needle punched fabrics deliver high-strength products with relatively high elongations that offer high survivability when implemented with engineered design.
Applications
- Separation and Filtration: Prevents intermixing of subgrade soils and subbase materials and preserves the characteristics of the aggregate material.
- Subsurface Drainage and Transmission: Placed as a drainage within the soil and allows long term drainage, preventing migration of soil particles and exhibiting excellent transmission property.
- Erosion Control: Minimizes the movement of soil particles with surface water and prevents erosion of soil on a slope.
- Silt Fence: Acts as a temporary barrier to mitigate silt and other sediment from polluting nearby streams, rivers and sensitive environments.
