Armor Bags

are custom fabricated to fit job site requirements. Inlet valves, attached by fabric flange to a slit in the surface of the bag, provide positive self closure. Armor Bags offer an effective, adaptable and economical alternative to the expensive and labor-intensive placement of rip rap—heavy boulders, or large precast concrete blocks.

Available in a wide assortment of dimensions to ensure compatibility with your applications. The bags provide the formwork required to cast concrete elements with the mass and stability to withstand the waves and/or rapidly flowing water. The concrete grout bags may be placed side-by-side or stacked to form an inherently interlocked concrete structure. Armor Bags can be positioned and filled with concrete from the surface in shallow water or by divers in deeper water. Since they are cast-in-place, they intimately adapt to variations in the subgrade or bottom contours.
