  • Geosynthetics Market Report

    Sponsored by Geosynthetic Materials Association

    The most comprehensive and accurate measure of the geosynthetics market in the U. S. and Canada is now available from GMA. Here are some highlights.

    Geosynthetics manufacturing

    The Geosynthetics Market Report notes that there are currently 40+ geosynthetics manufacturing companies in the U.S. and Canada, with more than 50% located in southeastern part of the U.S. and Texas. There are more than 12,000 U.S. jobs in geosynthetics manufacturing, distribution, fabrication and installation.

    Sales

    Sales of geosynthetic materials are generally through distribution networks. Some distributors are exclusive or “captive” to one manufacturer, but most are not. Some manufacturers may sell directly to some project owners (usually when very large quantities are involved).

    Industry support

    Nearly all installers of geosynthetic materials in the U.S. and Canada are trained and certified, many through IAGI (International Association of Geosynthetics Installers).

    The geosynthetics industry is supported by testing companies that can verify the specifications of geosynthetic materials. And the industry is further supported by a large and active network of engineering consultants and also many academics (professors).

    Statistics

    • In 2007, U.S. geosynthetics sales totaled $1.89 billion.
    • Geosynthetic materials represent ~0.33% of U.S. transportation spending.
    • Knowledgeable estimates project that amount has the potential utilization.
