Carthage Mills

Beginning in 1958, Carthage Mills set out to pioneer the development, manufacture and application of an innovative ‘woven synthetic filter cloth’, as the first alternative to costly, and largely ineffective, ‘graded granular filters’ under riprap in shoreline protection. Those early ‘plastic filter cloths’ eventually became known as “Geotextiles”; the industry that followed – “Geosynthetics”; and Carthage Mills – America’s FIRST Geotextile Company.
The company combines an industry leading selection of geotextiles, geogrids, erosion control, geomembranes, and other geosynthetics with unparalleled Customer Service and over half-a-century of practical application experience, making it the obvious answer for all your geosynthetic needs.
Geotextile Fabrics – the oldest and most commonly used geosynthetic today – are engineered to provide cost-effective solutions to meet specific design requirements. And although there are at least 80 specific ‘applications’ for geotextiles that have been developed, a geotextile always performs at least one of five discrete ‘functions.
Their 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 interaction between the geogrid, aggregate and some soils. Also, the apertures ensure vertical drainage of a reinforced free-draining aggregate/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 (punched and drawn sheets; or extruded), ultrasonically or adhesive bonded strips, or joined in a knitting or weaving process and then coated. Polymer types include polyethylene, polypropylene or high tenacity polyester that has been 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.
