Extreme direct shear testing

February 1st, 2021

By George R. Koerner The Geosynthetic Institute (GSI) is doing direct shear testing under extreme environmental conditions (i.e., specifically extreme temperatures). At the prompting of two member companies, we have initiated an effort in this regard. This work looks at response curves over a wide range of normal pressures, 0–43.5 psi (0–300 kPa). The work […]

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 […]
