Most of the existing rubber dams are of air filled types. Water filled rubber dams are not preferred for the following reasons:
(i) By giving the same sheet length and dam height, the tensile stress for water-filled dams is higher than that of air-filled rubber dams.
(ii) A significant size of water pond is normally provided for water-filled water dams for filling the rubber dams during the rising operation of dams.
