Description


AJs are high stability concrete armour units that are used in river, lake, and coastal applications to control erosion, stabilize shorelines, and provide habitat.  In open channel applications they are used for bank and toe protection, flow and grade control, bridge pier scour protection, energy dissipation, and habitat.  In coastal applications AJs are used for reefs, revetments, breakwaters, and jetties and to provide habitat.
