ABSTRACT:
An erosion control block of octagonal shape, having a pair of arms extending from a peripheral side edge thereof, and a pair of cavities formed in the block with openings to the peripheral side edge. The block interlocks with other similar blocks and provides an effective interlocked matrix of such blocks. The arms have enlarged ends that loosely fit within the cavities, thereby allowing rotation about a vertical axis of one block with regard to another block. When two blocks are interlocked and rotated to the fullest extent, peripheral edges of the blocks abut, thereby placing a radial tension strain on the neck of the arm, rather than a lateral strain, thereby reducing the possibility of breakage of the arms.
