Maintainable Weep Hole Component

Retaining walls, bridge abutments, sheet piling and seawalls are failing daily in all parts of the world due to the lack of proper erosion control.

The JET FILTER prevents wall failure/movement by relieving water pressure and allowing drainage while saving time & money on extensive repairs.

The JET FILTER relieves the hydrostatic pressures created by rain water as well as tidal surges trapped behind erosion control structures such as:

• Seawalls
• Bulkheads
• Retaining Walls
• Sheet Piling
• Bridge Abutments

The purpose of the weep holes is to relieve the hydrostatic water pressure that inevitably will be behind the wall. These weep holes should also be maintained periodically to insure that they do not become clogged.

Panel seams which have opened up or toe failure of the wall can be an indicator of unrelieved pressure due to clogged or insufficient weep holes.

If the tiebacks deteriorate sufficiently and water pressure builds up behind the seawall, either from heavy rain or a storm surge, the cap can crack through and the wall collapse outward.

The media equipped in the JET Filter System is the highly rated Mirafi® Filter-weave FW 300 series. This media maintains long-term flow rates in high gradient and dynamic conditions.

With its removable inner cartridge, the filter can be changed and cleaned if needed, from the front side of the earth retaining structure without dredging from behind to replace the erosion control fabric.
