In coastal applications A-Jacks are used as breakwaters, revetments, artificial reefs, and habitat development. In breakwater applications, A-Jacks can be an economical alternative to quarried rock, which can be both heavier and unwieldy; over the course of a breakwater construction project, the number of transportation cycles to deliver product to the site can be reduced substantially, since A-Jacks are delivered flat on trucks whereas rock rip-rap would be brought in dump trucks.
A-Jacks are versatile coastal structures used for breakwaters, revetments, artificial reefs, and habitat development. They offer an economical alternative to quarried rock, which is heavier and more cumbersome to transport. A-Jacks' flat delivery format reduces transportation cycles during construction compared to quarried rock delivered in dump trucks.
