The advanced drainage technology of the JET Filter prevents wall failure/movement by relieving water pressure and allowing drainage while saving time & money on extensive repairs. You can see an example below from a weep hole seawall repair.
This 4″ diameter geocomposite wick drainage system is ideal for relieving the hydrostatic water pressure.
The media equipped in the JET Filter System is the highly rated Mirafi® Filter-weave FW 300* series and 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.
