Geotex 401

Non-woven Separation Fabrics

Non-woven geotextile fabrics are generally used for reinforcement, separation, filtration, and erosion control. These fabrics are durable on a varying scale with the heavier fabrics being the most resilient to tearing. Polypropylene staple fibers combine high water flow rates which are an ideal material choice for use in various drainage applications. Aside from drainage, non-woven fabrics can also be used as an underlayment in road stabilization.

When used in drainage applications non-woven geotextiles offer excellent filtration characteristics and prevent dirt and aggregate from clogging up drainage systems which can help to extend the system’s life and increase its performance.

Other applications include under walkways, patios, landscape, water features, under riprap to redirect excess water, erosion control, retaining walls, and shoreline protection. Thinner fabrics (lighter weight) fabrics are typically used for drainage while the thicker fabrics are most often installed in erosion control or stabilization scenarios. The GEOTEX 401 is on the lighter side and is perfectly suited for general drainage applications. Be sure to consult with an engineer or landscape architect on the most appropriately weighted fabric for your specific application.
