Articulating Block Matsprovide a cable-reinforced, articulating concrete block mattress for use over soft subgrades or where a revetment is exposed to attack by waves. When filled with a fine aggregate concrete, they form a system of staggered, interconnected, cable-reinforced, concrete blocks. The permeable interwoven perimeter of each block serves as a drain, filter, and hinge. The hinge permits articulation of the filled compartments (blocks). Factory installed high-strength cables and optional transverse cables are threaded between the two layers of fabric and through the fabric form's grout ducts to link the concrete blocks. The cables are self-positioning within the fabric formed concrete blocks and are embedded at approximately the vertical center of the concrete blocks. |
