Recent Webinar on Injectable Barriers™ is Popular Learning Opportunity

By Robert Armstead

The recent webinar Ground Works hosted on Injectable Barrier Walls, titled Trenchless Applications for Restricting Groundwater and Contamination movement, provided an excellent learning opportunity for engineers, environmental consultants or for those seeking to learn more about innovative applications for subsurface barrier walls, curtain walls or for stabilizing soils for trenching.

Robert W. Moody, Jr., Ground Works’ President, presented along with Tim Harmon, P.E. with Handex/HCR. They presented three case studies presenting environmental containment and control and seepage management for dams, dikes, levees, and water control structures. Some of these presentations included the FDOT SR7 Injectable Barrier Wall, FPL Headwall Installation and the Handex Consulting and Remediation FDOT Riviera Beach subsurface contamination groundwater restriction project.

The webinar lasted for about approximately 50 minutes, however the subject matter of the webinar must have highly intrigued the audience. Mr. Moody and Mr. Harman went on to answer questions and discuss the applications in a highly informative 45-minute Q&A session. The Q&A session provided deep insights into the technical approaches and various applications of the Injectable Barrier Walls, including restricting groundwater movement into construction zones (limiting the need for pump and treat systems and dewatering),  resticting contamination migration, stabilizing loose soils for excavation, sealing sheetpile systems against groundwater or soil movement, and much more.

Our next webinar is called Geotechnical Aspects of Polyurethane Grout and it is scheduled for Friday, September 16, 2016, from 2 to 3 pm. You can register for it here.
