Separation Critical

Separation critical woven products offer a solid combination of separation, filtration, and durability capabilities, allowing them to often be the "products of choice" for a broad spectrum of applications including roads, pond capping, low-energy shorelines, and resource recovery operations. Each of these woven geotextiles is composed of high-quality polypropylene resin and carbon black.
