    Failed Concrete Slab Expansion Joint
    I have a concrete expansion joing that failed. Looks to me like it was not the fiber type expansion joint, but some type of wood. Is there material I can fill the void, 3/4", with and it will expand and not rot.

    You might want to place a caulking rod in the joint before caulking, like ballangerb1 says.
