An articulated, predominantly concrete mat. Discrete, concrete blocks conforming generally to rectangular solids are arranged in a grid, preferably a rectangular grid. A geogrid of a type capable of being handled in one piece by itself is embedded in each block. In a preferred form, the geogrid is a flexible, one-piece sheet of oriented, polymeric material. In an alternative form, the geogrid is a weave of flexible, discrete straps of oriented, polymeric material that are joined where they intersect. Each block has a hole extending therethrough and communicating with an aperture of the geogrid.
