The Original
and now introducing the NEW
The Patented Blue Marlin Filter is a seawall erosion control drainage system.
It is used in both new and retrofit applications in seawalls, retaining walls, bulkheads, shoring and erosion control structures. Designed and produced by a Marine Contractor, the Blue Marlin Filters are a great compliment to APE’s range of Plastic and composite piles.
The Blue Marlin Filter System is unique in its design to prevent erosion of backfill materials, caused by transport of the fill material fines through the wall’s weep holes and/or panel seams. The hydrodynamic pressure of perched water and seepage water causes loss of landfill without the proper erosion control system.
The Blue Marlin Filter System relieves this pressure and has an unlimited design life. Blue Marlin’s filter is also designed for both new and existing seawalls, retaining walls and bulkhead walls
New Applications
In new applications, the system may be installed at the time of the construction of the wall. The location of the Blue Marlin Filter System may be chosen by the designer of the wall to best serve the purpose of relieving the hydrostatic and hydrodynamic pressures on the wall. This relief is important in that the design of most wall systems do not anticipate that the wall will be subject to pressures from perched or trapped water behind the wall in the backfill material. The Blue Marlin Filter is a two component system consisting of an ABS plastic cylinder permanently installed seawalls/bulkheads and a replaceable filter element tube which can be inserted, locked in and removed for replacement purposes by the filter assembly tool.
The Original Blue Marlin filter and replaceable filter element
The original Blue Marlin Filter is made up of ABS UV protecting cylinders with a 50mm diameter available in various lengths. First, is the 75mm design made purely for the corrugated sheet pilings. Second, is the 230mm design (blue in colour) for concrete seawall panels and lastly, the 380mm design to be install for much wider seawall/bulkheads. The 230mm and the 380mm displays a scale to install right at the back side of the seawall/bulkhead. These cylinders slide into the existing seawall weep holes.
The cylinders contain a sliding replaceable filter cartridge (with a marafi filter weave #SRW300), which is inserted through the seawall, with the filter fabric flush with the landward side of the seawall.
A special tool is used to insert the filter cartridge and to retrieve the filter cartridge for replacement purposes. With the Blue Marlin Filter, the fabric cartridges can be replaced periodically simply by retrieving the filter cartridge and replacing it with a fresh filter cartridge.
No longer is it needed to bring in heavy equipment, dredging from behind the seawall, replacing the filter fabric, backfilling the seawall and replacing the landscape materials.
JET FILTER Wick Filter Drainage System
Our most powerful innovation yet!
 
The JET FILTER was created with our customers concerns of depth and protrusion in mind. The JET FILTER can be used for both new & retrofit applications in seawalls, bulkheads, retaining walls, & other erosion control structures.
Retaining walls are failing daily in all parts of the world due to the lack of proper erosion control. The JET FILTER prevents seawall failure by relieving 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
The JET FILTER installation is quick & easy. Simply drill a 2 ˝ inch core hole where directed on the sheet piling. The 4 self drilling stainless steel tap cons, make installation both fast & easy. Filters should be installed approximately 4 to 6 feet apart, slightly above the mean high water line. The filter fabric equipped in this design, (Mirafi Filterweave 300) resists clogging while maintaining flow in dynamic conditions. Properly maintained, the seawall will last a lifetime without major repairs
