Fabric, rubber or metallic expansion joints are often overlooked for signs that they are wearing out or getting ready to fail. Expansion joints are usually located in hard to see places, so fatigue spots, cracks, discoloration of the surface, or actual holes are not readily seen.
Most expansion joints, properly designed, have a long-life expectation. Improper designs, improper installation or incorrect engineering information can lead to a shortened life or unexpected failure.
