EROSION CONTROL MATERIALS PRODUCT DATA FOR MORE INFORMATION Geosynthetics magazine has provided information on the erosion control product specification charts for comparative purposes only. Designers should contact manufacturers for additional details and to discuss sitespecific considerations. Information on the use and specification of erosion control products is also available from the Geosynthetic Materials Association (GMA).

Companies provided specifications voluntarily, and specification accuracy is the responsibility of the manufacturer. The appearance of a listing in this directory is not an endorsement of the company or product by Geosynthetics magazine or the Industrial Fabrics Association International (IFAI). The Geosynthetics 2020 Specifier's Guide is intended as a guide, and Geosynthetics magazine and IFAI encourage readers to contact the companies listed for further information. Photograph courtesy Propex GeoSolutions Companies design these products to solve erosion and sediment control problems, and to provide long-term stabilization by establishing and maintaining vegetative cover. E rosion control products give engineers ready solutions for one of the fastest-growing design niches. Many of these products work with vegetation to form a biocomposite solution to erosion. The charts in this section are divided into degradable rolled erosion control products (RECP), nondegradable RECP and hard armor. Degradable products are used to enhance the establishment of vegetation, such as on a rehabilitated lakeshore or alongside a recently constructed roadway. These products are used where vegetation alone will provide sufficient site protection once the erosion control product has degraded. Nondegradable products provide long-term reinforcement of vegetation. They are used in more challenging erosion control applications where immediate, high-performance erosion protection is required. The materials extend the erosion resistance of soil, rock and other materials by permanently reinforcing the vegetative root structure. The numbers Companies that submitted product data chart lines were asked to provide data determined through industry-accepted testing methods. Companies signed a certificate of compliance verifying the accuracy of this data. www.GeosyntheticsMagazine.com 109http://www.GMAnow.com http://www.GeosyntheticsMagazine.com
