1 1204GFRspec_145.qxd 12/9/04 9:53 AM Page 145 Geogrid Product Data These products are designed for reinforcement and characterized by integrally connected elements separated by in-plane apertures. Geogrids form a distinct category of geosynthetics designed for reinforcement. These products are characterized by a relatively high tensile strength and a uniformly distributed array of large apertures (openings between the longitudinal and transverse elements). The apertures allow soil particles on either side of the installed sheet to come into direct contact, thereby increasing the Photo 1. Fill placement over geogrid. interaction between the geogrid and some soils. Also, the apertures ensure vertical drainage of a reinforced free-draining soil. The geogrid elements vary in polymer type and cross-sectional dimensions. They can sometimes change shape and dimensions within their length. Geogrids are either integrally manufactured, ultrasonically or adhesive bonded, or joined in a knitting or weaving process and then coated. Although geogrids are used primarily for reinforcement, some products are designed for asphalt overlay and waterproofing or for separation and stabilization. Geogrids also are used as gabions and sheet anchors, inserted between geotextiles and geomembranes, or used to construct mattresses for fills or embankments over soft soils. The numbers Companies that submitted product listings were asked to provide data determined through industry-accepted test methods. Each manufacturer has provided a signed certificate of compliance verifying the accuracy of its numbers. For more information The specification charts have been provided for comparative purposes only. Designers should contact manufacturers for additional details and to discuss site-specific considerations. See page 61 for an article index from GFR s 2004 volume. These articles provide project reports, research notes, and discussion fodder for readers using the geogrid data in this section. Information on the use and specification of geogrids is available from the Geosynthetic Materials Association (GMA). Contact GMA, 1801 County Rd. B W., Roseville, MN ; , fax , gfr@ifai.com, Web site at Publisher s note Product information included in the Specifier s Guide was submitted voluntarily. The accuracy of the data is the responsibility of the manufacturer. The appearance of a listing in this directory is not an endorsement of the company or product by GFR or its publisher, the Industrial Fabrics Association International (IFAI). The Specifier s Guide is intended as a guide, and GFR and IFAI encourage readers to contact the companies listed for further information. Photo 2, Figure 1.

17 1204GFRspec_159_161.qxd 12/7/04 11:45 AM Page 161 Geocell Product Data Geocells are engineered for protection and stabilization applications. They improve the behavior and performance of standard materials and erosioncontrol treatments. Geocell products are three-dimensional, expandable panels made from high-density polyethylene (HDPE), polyester or another polymer material. When expanded during installation, the interconnected strips form the walls of a flexible, three-dimensional cellular structure into which specified infill materials are placed and compacted. This creates a free-draining system that holds infill materials in place and prevents mass movements by providing confinement through tensile reinforcement. Cellular confinement systems improve the structural and functional behavior of soils and aggregate infill materials. Geocell products were developed in the late 1970s and early 1980s. The primary geocell applications are: protection and stabilization of steep slope surfaces protective linings of channels and hydraulic structures static and dynamic load support on weak subgrade soils multi-layered earth-retaining and water-retaining gravity structures Infill selection is primarily governed by the nature and intensity of anticipated working stresses, the availability and cost of candidate materials, and in some instances the aesthetic requirements for a fully vegetated appearance. Basic geocell infill types are aggregates, vegetated topsoil, and concrete. The numbers Companies that submitted product listings were asked to provide data determined through industry-accepted test methods. Each manufacturer has provided Photo 2. Creating a terraced wall. The geocell panels were installed horizontally and stacked. Geogrid reinforcement was used for every fourth layer. Photo 1. Heavy storms had eroded the slope above this railway. Geocells were installed and filled with drainage stone. The erosion ceased. a signed certificate of compliance verifying the accuracy of its numbers.
