Articulating Concrete Block (ACB's)

Articulated concrete blocks are revetment systems that can be made in a wide variety of shaped and thickness. It also can be defined as a grid of interconnected concrete block units used for erosion protection of embankments or slopes. The articulated blocks are connected by cables, geotextiles or geogrids, including typically a geotextile membrane underlayment that allows hydraulic infiltration and exfiltration to occur while providing particle retention. The blocks are made of precast concrete and cast into interlocking or non-interlocking shapes.
