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…

Installation of In-Situ Grout Wall for Florida Department of Transportation

By uretekhr

In this video, Bob Moody, URETEK’s Florida President, narrates the process and procedures for installing a 290 LF in-situ grout wall utilizing URETEK’s 486STAR rigid structural geotechnical polymer.

URETEK performed 490 injections at 58 points.  This created a hydraulic barrier that restricted groundwater movement from a contaminated site to a construction site where drainage features were being installed by FDOT.  This removed delays to the project as construction dewatering would have been impacted by the contamination.

The FDOT team received the Prudential-Davis Productivity Award for this project for utilizing an innovate process to minimize contamination impacts.  They also saved approximately $900,000 in costs.
