Erosion Control With Filtration

Filtration and drainage are a vital part of designing Earth Retaining Structures including coastal retaining walls, bridge abutments, wing walls, all types of sheet piles, etc. The vast majority of retaining structure failures occur due to the build-up of excessive hydrostatic (water) pressure caused by either a lack of adequate drainage or impermeability of the backfill materials. Ports, Harbors and Marinas experience extreme rising and falling water levels and intense storms that cause groundwater to build up behind the wall. Structures that don’t have an adequate drainage system have increased hydrostatic pressure causing additional stress on the structure.
