The Geosynthetic Materials Association (GMA) represents all segments of the 

geosynthetics industry, including manufacturers as well as companies that test or 

supply material or services to the industry. GMA activities further the acceptance 

and use of geosynthetic materials in a variety of applications.  

For additional information please contact Danette Fettig, managing director, 

GMA, tel:[phone]; [e-mail] or www.gmanow.com.
