Armortec Family of Products A-Jacks
A-Jacks Concrete Armor Units

A-Jacks are high stability concrete armor units designed to interlock into a flexible, highly permeable matrix. A-Jacks can be installed either randomly or in a uniform pattern. The interstices formed within the A-Jacks matrix provide approximately 40% void space in the uniform placement pattern. The voids provide habitat for fish and other marine life when applied as a reef, revetment, or as a soil support system in river applications.
