Geosynthetic Materials Testing

As one of the specialized laboratories of the National Center for Building Materials Testing and the National Center for Quality Supervision and Testing of Building Materials, the Geosynthetics Testing Laboratory has developed over the years a professional technical testing team and is equipped with internationally advanced testing instruments. The laboratory operates a quality system established and maintained in accordance with ISO/IEC 17025. As a third-party laboratory, it can conduct various performance tests on geosynthetics in compliance with the technical requirements of domestic and international standards such as GB, CJ, JT, SL, JC, JG, Q/CR, ASTM, ISO, and GRI.

Over the years, the laboratory has consistently adhered to its mission of serving economic development, closely monitoring market developments and client needs, and strictly following the guiding principle of “Scientific, Fair, Accurate, and Efficient.” Leveraging advanced testing equipment and extensive experience in testing and evaluation, it provides high-quality testing services to clients from all sectors of society.
