Testing wind-resistant geosynthetics

October 1st, 2020

By George R. Koerner As you can see by Figure 1, we are experiencing a new age of geosynthetics. Over the past 15 years, we have seen a propensity of polymeric materials left exposed to rather than covered from the environment. This is in large part due to the strides geosynthetic manufacturers and polymer formulators […]
