Abstract
A connection for securing a geogrid fabric to between two tiers of concrete blocks which are stacked to form an earth retaining wall. A groove is formed in the top of each block in the lower tier to extend across the width of each block substantially parallel to the face of the block. The fabric is positioned to extend from the rear of the block over the groove and a first rod is positioned in the groove over the fabric. The fabric is folded to wrap around the first rod to extend past the groove towards the rear of the block and a second rod is positioned in the groove over the fabric to the rear of the first rod. When an upper tier of blocks is stacked on the lower tier, the rods and fabric are locked into the groove in the lower blocks.
