Earth Retaining Structures (ERS) are failing daily due to clogged or insufficient drainage systems. The JET Filter System uses the highly rated Mirafi® Grotextile Filter-weave to prevent soil loss while draining excess water.
The JET Filter maintains long-term flow rates in high gradient and dynamic conditions and relieves the hydrostatic pressures created by rain water as well as tidal surges trapped behind erosion control structures.
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.
A lack of erosion control that causes sinkholes is a vital issue with a concrete seawall design.
One common problem is wall movement in addition to tieback/whaler tension, toe failure, horizontal cracking, panel separation and stress.
Other considerations are wave forces, toe scour, wave overtopping and storm surges.
Vinyl Sheet Piling, Z Type Steel Sheet Piling, FRP Composite and Aluminum Sheet Piling
Interlocks sheet pile structures will experience the build-up of significant hydrostatic water pressure, a vital issue for a sheet piling design.
JET Filter components are made in the USA and are compliant with the Buy American Clause.
Proper maintenance and inspections can also help avoid major disasters. Water run-off without drainage may weaken bridge abutments and wing walls by eroding the material that supports the structure. Furthermore, poor drainage may cause considerable challenges by settling behind the wall and saturating the soil with incredible pressure.
Concrete lined channel structural problems are indicated by cracking, exposure of reinforcing bars, and large areas of spalled concrete along with soil loss from existing weep holes. Even if the spillway is in good structural condition, seepage under the spillway or erosion at the outlet or along the sides can cause the spillway to fail.
Spillway floor slabs and walls should be checked for erosion of underlying base material known as undermining.
Proper venting of the wooden bulkhead is absolute paramount, as water will enter the wall from rain, runoff, irrigation, etc.
Forces of nature and physics all work symbiotically to create a fully functioning wall assembly that vents properly and this action maintains the soil density behind the bulkhead.
The purpose of installing weep holes in a wooden bulkhead will relieve the hydrostatic water pressure that may settle or rest behind the wall.
The life expectancy of a retaining wall can be increased simply by adding sufficient drainage.
Dry soil may provide little stress on a retaining wall, however heavy soil without proper retaining wall drainage may cause the wall to buckle or lean.
