TRB Webinar: When to Use Fully Grouted Piezometer Installations

July 8, 2020

2:00 PM - 3:30 PM (EDT)

Past

Topics

The fully grouted method of installing piezometers is increasingly popular, but it doesn’t work in every case. TRB hosted a webinar on Wednesday, July 8, 2020 from 2:00 PM to 3:30 PM Eastern to provide critical information regarding the most effective piezometer installations for the applications at hand. It focused on which factors to consider when deciding on a fully grouted installation rather than a conventional sand pack type. Presenters discussed the consequences of selecting the inappropriate methods. They included case studies to demonstrate some of the difficulties analyzing data and to highlight reasons for what might appear to be erroneous data.

This webinar was organized by the TRB Standing Committee on Geotechnical Instrumentation and Modeling.

The slides and a recording are available.
