Abstract
A resilient expansion joint insert member for insertion into the expansion joint between adjacent concrete floor slabs. As the concrete slabs move further apart due to settling or thermal contraction, insert member covers the widened gap. Likewise, as the concrete slabs move closer together due to settling or thermal expansion, the insert member is compressed and absorbs the force as the slabs move against each other. The flooring material on the slabs near the expansion joint move beneath a cap of the insert member.
