WEBINAR: Acrylamide Grout Saves the Day for TBM in Portland, Oregon

The design of the Balch Tunnel - located in Portland, OR - called for the use of a Tunnel Boring Machine (TBM) in the gravel substrate of the area. As the TBM progressed, soil stabilization was required to keep the TBM in alignment. To stabilize the gravel in front of the TBM and after multiple product considerations, AV-100 Chemical Grout (Acrylamide) was used, allowing the project to continue as planned. This 75-minute webinar will discuss an overview of the different types of injection grouts, where they are used, and in what applications, and then dives deep into the design and details of the Balch Tunnel Grouting Project.
