A-Jacks

A-Jacks are concrete structures that come in various sizes, 24” A-Jacks are the most commonly used locally.  When the A-Jacks are installed, they are seated together to make one monolithic structure that is capable of withstanding much greater flows than rock rip-rap.  Their typical use is stream bank scour protection and culvert outlet protection.  Where rip-rap migrates A-Jacks will not!
