Patent ID: 8132380

Claim:
A system for the repair or replacement of expansion joints for concrete slabs, the system comprising: concrete slabs comprising rounded edges above substantially parallel opposing faces, wherein the concrete slabs are separated so as to form a space between adjacent slabs; a compliant trim occupying the space between said adjacent concrete slabs, wherein said compliant trim further comprising: a depth limiting means; wherein said depth limiting means substantially occupies the volume between said rounded edges of said adjacent concrete slabs; wherein said depth limiting means has a width which is larger than the distance between said parallel opposing faces of said adjacent concrete slabs and is located substantially flush or below the surface of said adjacent concrete slabs; and wherein said depth limiting means has a surface having a convex curvature such that when said compliant trim is placed between said adjacent concrete slabs, said surface of the depth limiting means maintains said convex curvature and minimizes the surface volume for the accumulation of particulate; and an anchoring means; wherein said anchoring means frictionally holds said compliant trim in place by acting on said parallel opposing faces of said adjacent concrete slabs.
