Abstract
A revetment block comprising a body having a first surface, a second surface and a plurality of peripherally extending side edges. The body has at least two arms extending laterally outwardly from the respective side edges and at least two sockets extending laterally inwardly from the respective side edges. There is at least one hole extending through the body, the hole having a first and a second portion. The first portion of the hole opens through the first surface of the block while the second opens through the second surface of the block. The first and second portions intersect interiorly of the block. The cross-sectional area of the first portion is less than the cross-sectional area of the second portion at the intersection of the first and second portions. Accordingly, the intersection of the first and second portions forms a ledge.
