SGI Testing Services, LLC (SGI_SM), a Georgia Limited Liability Company, 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–SGI® from GeoSyntec Consultants, Inc. by Mr. Robert H. Swan, Jr. and Dr. Zehong Yuan, the former management of GeoSyntec–SGI® for fifteen years, and now 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. In order to maintain this quality, the laboratory has an established Quality System that includes a Quality Manual with written policies, procedures and guidelines for the testing and reporting. This Quality System was established in accordance with the American National Standard Institute quality standard ANSI/ISO/ASQC Q9001-2000 and ISO/IEC Guide 17025. The Quality System includes thorough internal reviews of test results and testing procedures. In addition, strict confidentiality and chain of custody procedures apply to all testing and reports.

The owners of SGI are committed to keeping client schedules on track with rapid sample turn-around and on-site testing support. Our laboratory professionals are active in the American Society for Testing and Materials (ASTM), are regular contributors to technical journals and conference programs, and are leaders in test methods standards development.

SGI is accredited by the Geosynthetic Accreditation Institute – Laboratory Accreditation Program (GAI-LAP), Accreditation No. GAI-LAP-41-01. SGI is accredited for 18 different tests and its accreditation is valid through 30 June 2003. SGI is also certified under Nuclear Quality Assurance (NQA1) for conducting interface direct shear testing of geosynthetics used at low-level radioactive waste facilities.

SGI has been involved with the testing and evaluation of all types of geosynthetic interfaces since 1987. The laboratory has been on the forefront in the development of the testing procedures that are currently being used by the industry to evaluate various geosynthetic interfaces. SGI laboratory staff includes top professionals holding advanced degrees in geotechnical, environmental, and polymer engineering. SGI has: (i) worked with the majority of the geosynthetic manufacturers throughout their various stages of product development; (ii) conducted design/performance and quality control/quality assurance evaluations for numerous design/engineering firms; and (iii) conducted workshops for ASTM and the EPA on the testing and evaluation of all types of geosynthetic interfaces.
