Colorado state University (CSU) Engineering Research Center

Colorado State University’s Hydraulics Laboratory is part of a unique research facility designed for hydraulic model studies, hydraulic performance testing and research in the fields of open channel and closed conduit hydraulics. The laboratories are located at the Engineering Research Center on the Foothills Campus approximately four miles west of Fort Collins, Colorado.  Chris Thornton, Ph.D, P.E., is the director of the ERC.

Florida Atlantic University Geotechnical Testing Lab

The Department of Civil, Environmental and Geomatics Engineering houses one of the most comprehensive geotechnical laboratory testing facilities in South Florida. In addition to conventional soil and geomaterials testing equipment, the facility includes:

  • multiple direct shear devices
  • static and dynamic triaxial testing machines
  • unconfined compression devices, and  a group of ten consolidation testing machines.

The laboratory is used extensively to conduct projects sponsored by federal, state and local agencies and private industries.

Iowa State University GeoTechnical/Materials Lab

Geotechnical faculty and research staff continue the legacy of cutting-edge research, investigating issues related to soil mechanics, geomaterials behavior and stabilization, in situ testing environmental geotechnology and materials. Major initiatives include Iowa State University’s Center for Earthworks Engineering Research, an internationally recognized resource for earthworks engineering and geo-construction technologies. Faculty from geotechnical/materials engineering also are heavily involved in the nationally acclaimed Wind Energy Initiative at Iowa State.


SGI was established on 1 June 2001 with the intention of providing the highest quality testing services available in the area of Soil-Geosynthetic Interaction testing, following the purchase of GeoSyntec CSGI from GeoSyntec Consultants, Dr. Zehong Yuan, the owners of SGI.   SGI operates under procedures prescribed by ASTM, FTMS, ISO, USEPA, AASHTO, and other applicable standard-setting agencies. Compliance with demanding certifications and exhaustive quality control helps assure consistent value in laboratory testing services. SGI maintains a very high level of quality control on all test results and reports.


The Geosynthetic Institute (GSI) is a consortium of organizations interested in, and involved with, geosynthetics.  All types of polymeric geosynthetic materials are involved: geotextiles, geomembranes, geogrids, geonets, geocomposites, geosynthetic clay liners, geopipe, geocells, and geofoam. The organizations include federal and state governmental agencies, facility owners, designers, consultants, QC and QA organizations, testing laboratories, resin and additive suppliers, manufacturers, manufacturer’s representatives and installation contractors. GSI currently consists of 71 member organizations of which ca. 45% are international.
