SGI Testing Services

We have used Zehong and SGI for our shear testing for over 15 years and there is no comparison to any other laboratory. They monitor the testing very closely and their familiarity with geosynthetic materials, manufacturers capabilities and knowledge of how geosyntetic materials and soils interact is unmatched in the industry. In addition to performing shear testing in the most consistent manner with reproducible results, Zehong provides insight into what you can expect geosynthetic materials to do and not do in shear testing and how the results relate to the project designs. No one individual in the industry has the experience, knowledge and testing reproducibility that Zehong and SGI can provide.
