Abstract
A modular wall block is formed with recesses or troughs in a rearward end of its top and/or bottom surface configured to receive forward portions of a rigid grid connection device. Rearward end portions of the grid connection device extend beyond the rear face of the modular wall blocks. Extended lengths of a polygrid material are then secured to the rearward portions of the grid connection device for reinforcing the fill behind a retaining wall formed from a plurality of courses of said wall blocks. The grid-to-block connection does not rely on the weight or friction of superimposed wall blocks and is particularly effective in sites subject to seismic activity.
