Abstract
Abstract A soil reinforced structure comprised of superimposed courses of concrete blocks, at least some of which have rearward portions separable therefrom. Longitudinally extending soil reinforcing members extend around the separable rearward portions and are captured between the courses of blocks thereabove and therebelow. In one embodiment the blocks have bifurcated forward portions about which a cast in place concrete face may be formed. Another embodiment disposes courses of the blocks in opposed spaced relationship and extends the soil reinforcing members between the blocks to form a earthen fortress.
