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 […]

Q: Can we correlate laboratory versus outdoor weathering of geomembranes? I would appreciate your thoughts on this matter because we are getting technical challenges on this issue from regulators. A: Yes, we do this all the time. The results are location dependent based on ambient temperature and solar radiation. We have several papers on the […]
