Abstract
A compression seal for concrete expansion joints is extruded as a one-piece unit from rubber-like material. The compression seal includes a compressible sealing portion and a pair of load-bearing wings that extend laterally from the compressible sealing portion. The one-piece design facilitates easy installation of the compression seal in an expansion joint. In use, the compressible sealing portion is inserted the expansion joint. Simple zipper-like motion may be used to press fit the compressible portion into the expansion joint. The lateral load-bearing wings are bonded to concrete surfaces adjoining the expansion joint to hold the compressible sealing portion in place.
