GeoSystemsGEOSYNTHETICS TESTING Tests performed by the GeoSystems geosynthetics laboratory include both standard and specialized procedures for determination of physical and engineering properties of geosynthetics. All laboratory staff receive test performance training based on American Standards for Testing Materials (ASTM), Geosynthetic Accreditation Institute (GAI), and GeoSystems' own in-house quality assurance standards. GeoSystems is an accredited through the Geosynthetic Accreditation Institute-Laboratory Accreditation Program (GAI-LAP).
GeoSystems uses automated data collection systems on selected geosynthetic tests. This serves to reduce human error and improve the overall quality of the test results in the laboratory.
GeoSystems is an active member of the Geosynthetic Accreditation Institute (GAI). Geosynthetics are increasingly being used, especially in landfills, and new materials are continually entering the marketplace. GAI membership provides GeoSystems with unique capabilities in the use of geosynthetics.
