This floor expansion joint detail shows a pre-finished floor expansion joint cover equipped with a suspended water barrier set between concrete slabs. The assembly on the left incorporates a light-weight concrete topping and a waterproofing membrane over a drainage system, all sloped to drain above concrete over metal deck supported by a steel beam. The adjacent side features concrete over compressed rigid insulation. Painted steel angles support the joint assembly edges.
