These TerraTextile\u2122 NW needle-punched non-woven geotextiles are manufactured by mechanically orienting and interlocking polypropylene (PP) fibers forming a carded web. With the combination of drafting and heat, the finished fabric delivers high strength with relatively high elongation properties which offer high levels of survivability when properly used within an engineered design or consultation with Reinforced Earth engineers.<\/p>\n
TerraTextile\u2122 NW non-woven geotextiles allow for various applications:<\/p>\n
> Separation and filtration:<\/strong> preventing intermixing of subsurface soils and sub-base materials and preserves the characteristics of the aggregate material.
\n> Drainage:<\/strong> when placed as a drainage conduit within the soil, long-term drainage is assured through the prevention of migrating soil particles, and this control results in excellent flow transmission.
\n> Erosion control:<\/strong> minimizes the movement of soil particles within surface water and prevents erosion of soil on a slope.
\n> Pipe and aggregate\u00a0<\/strong>wrapping:<\/b>\u00a0mitigates clogging of flow receptors and drainage pipes through filtration.
\n> Filter fabric:<\/strong> used to restrict fine soil particles from migrating through wall, ceiling and floor joints.
\n> Pavement overlay:<\/strong> providing a protective barrier between pavement layers for improving strength and durability.
\n> Silt fence:<\/strong> acting as a temporary barrier to mitigate silt and sediments from polluting nearby streams, rivers and sensitive environments.<\/p>\n
