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) pressures 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.

The Jet Filter System will facilitate drainage and reduce water pressure while still preventing the loss of soil materials through the structure thus preventing erosion and wall failure.

The JET Filter System is a weep hole component available in 3 different diameters: 2 ½” in, 4” in & 6 in”.
Type: Open-End and Closed-End solutions.

The flush-mount wick dewatering filter units can be permanently installed on the front side of any earth retaining wall structures for drainage such as Bridge Abutment, Wing Wall, Steel Sheet Piling, Vinyl Sheet Piling, Seawalls, MSE Retaining Walls and Flood Control Channels.

Maintainable with the ability to remove and clean the filter media cartridge when needed to ensure the life of the wall from movement and/or failure.
