Box culvert repair in St. Louis military cemetery

Jefferson Barracks National Cemetery is one of the nation’s largest military burial sites, and it sits on the banks of the Mississippi River in St. Louis. A planned expansion in 2011 revealed that two box culverts adjacent to the expansion area were experiencing significant groundwater infiltration. More than 100 joints needed repair, with some of the joints having separated as much as three inches. Two hydrophilic, water-activated polyurethane injection resins, activated oakum and an epoxy gel were used to solve this problem. Read more about the project here.
