New test method for controlling the manufactured geometry of geosynthetics

February 1st, 2024

Figure 1a: Photograph of uniaxial geogrid The Geosynthetic Institute (GSI) has a new test method for determining bow and skew of geosynthetics. This method was created to give installers and product users a way to quantify the geometric quality control of goods they have purchased. Geosynthetics are ever increasingly integrated into transportation, geotechnical and environmental […]
