A-JACKS® Concrete Armoring Units

ENGINEERED SOLUTIONS A-JACKS® CONCRETE ARMORING UNITS (CAU)

Streambank Stabilization, Scour Protection and Energy Dissipation

A-Jacks concrete armor units are designed to interlock into a flexible, highly permeable matrix. The ability of the A-Jacks system to dissipate energy and resist the erosive forces of flowing water allows it to protect against scour and erosion.

A-Jacks hard armor solutions can be installed either randomly or in a uniform pattern. The voids formed within the A-Jacks matrix provide approximately 40% open space in the uniform placement pattern. These voids provide habitat for fish and other marine life when applied as a reef, revetment or as a soil support system in river applications. In addition, the voids may be backfilled with suitable soils and planted with a variety of vegetation including grasses, shrubs and trees above the normal base flow.

A-Jacks provide a cost-effective solution compared to conventional hard armor methods. Field tests and real-world applications confirm A-Jacks provide a flexible, non-eroding barrier. The patented, two- component design allows economical transport and on-site assembly. HAND-PLACED SOLUTIONS
