Matrix Riprap Provides More Riverbank Protection at Lower Cost

By Will deRosset The faster that water rushes through a river, the more erosion occurs on the river’s banks. Riverbank erosion can lead to a host of problems, including compromised bridges and adjacent roadways and loss of property. Protecting riverbanks from erosion correlates directly to increasing public safety. Water moving downhill has energy, and if… Read More »
