Abstract: Means for improved erosion control comprising a concrete module having a base, two upwardly extending sidewalls, an upwardly extending rearwall, a wave-disrupting ramp extending between the side walls from the base to the rear wall, and holes to aid in lifting and placement of the module and to link adjacent modules where a plurality are used to build a breakwall. A method for controlling erosion due to wave action comprising at least one module, and preferably fastening together a plurality of modules with flexible means thereby causing interference with wave action while permitting the individual modules to conform to wave action and bottom conformation.
