Abstract
An tensile reinforcement-to retaining wall connection for a retaining wall (10) having stacked tiers (14, 16) of blocks (12) having channels (52, 54) in opposing surfaces (48, 50), which channels (54, 56) in adjacent tiers (14, 16) align to define a receiving conduit (18) between the adjacent tiers. An isolator sheet (20) overlies the channels (52) in the blocks (12) of the lower tier (14) at selected vertical intervals in the wall (10). A tensile reinforcement sheet (28) partially overlapped (26) defines a pocket (24) that receives a connector bar (22), which sit on the isolator sheet (20) in the receiving conduit (18). A portion of the tensile reinforcement sheet (28) extends from the wall (10) for receiving backfill to mechanically secure the wall to the backfill. The isolator sheet (20) protectingly reduces abrasion of the tensile reinforcement sheet (28) in the receiving conduit (18). A method of connecting a tensile reinforcement to a retaining wall with reduced abrasion is disclosed.
