Injection grouting has long been trusted to stop infiltration—but what if it also stabilizes the ground surrounding buried infrastructure? New findings from the NASSCO Test Cell Study reveal compelling evidence that grouting improves trench and bedding stability, offering municipalities a powerful, data-backed strategy to extend sewer system life. Hosted by NASSCO, presenters include Marc Anctil, James Shelton, and John Manijak. This 1-hour experience dives into the world of injection grout and the discusses the test cell methods and revealing findings on ground stabilization of pipes and structures in collection systems.
