A connection securing a geogrid fabric to between two tiers of stacked
concrete blocks which 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 the
block with grooves in adjacent blocks aligned. The groove is slightly
wider that the rod and fabric wrapped around the rod and is deeper than
its width. The fabric extends from backfill behind the wall over the
groove. A rod is positioned over the fabric above the groove and pushed
into the groove. A free end of the fabric wraps around the rod and
extends from the groove towards the rear of the block. A wedge is
positioned in the groove above the fabric and rod. When an upper tier of
blocks is stacked on the lower tier, the rod and fabric are locked into
the groove.
