Abstract
A retaining wall for reinforced infill material of the type comprising superimposed courses of modular blocks, each block having a front face, a rear face, parallel upper and lower faces, and opposed sidewalls which extend between the upper and lower faces. Reinforcement material extends back from the wall into the infill material with an end portion of the reinforcement material interposed between two superimposed coursed of the wall and anchored to the wall by an anchor element which is retained in a retaining cavity between contiguous upper and lower faces of blocks in the superimposed courses. The anchor element has a spine which is of wedge-shaped cross-section for at least part of its length and has a plurality of spaced-apart projections extending from one side there of and engaging through apertures in the reinforcement material.
