The rubber dam is a permanent structure comprising a sheet of rubber-coated fabric (rubber body) which is fixed to a reinforced concrete foundation using clamp plates and anchor bolts. The rubber dam is inflated by pumping air or water inside the rubber body until the design height or pressure is reached. It is deflated by allowing the air or water inside the rubber body to escape.
