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.
Benefits of the A-JACKS System:
- Unique design - Provide fast, hand-placed installation.
- Meet guidelines - Adhere to HEC-23 design guidelines.
- Cost-effective - Reduce velocity less expensively than cast-in-place alternatives.
- Prevent undermining of stream toe - Help protect the entire slope to alleviate future issues.
