2020 GRIP Meeting

Meeting Information

August 4, 20, 27, 2020

In an effort to continue the Geotechnical Research in Progress (GRIP) meeting for the 33rd year and to keep attendees practice social distancing in current pandemic state, we will be providing the conference through a webinar series broken into three segments for three difference days. PDH credits will be offered for individuals that register and sign into the webinar series independently. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations. Certificates will be emailed to the email address you registered for the webinar.

You must register individually for each webinar series at the following links :
