This video shows a recent installation by J&N Construction out of Gaylord, MI of the 4″ Open-Ended Conical Weep Hole Filter by JET Filter Systems for the Michigan Department of Transportation. The 4″ Weep hole Filters were installed in a precast concrete box culvert to help ensure effective drainage of water collected behind the culvert wall. The Filter will relieve hydrostatic pressure buildup while preserving the support soils behind the wall.
