How do we compare air filled and water filled rubber dams?

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.

This question is taken from book named – A Self Learning Manual – Mastering Different Fields of Civil Engineering Works (VC-Q-A-Method) by Vincent T. H. CHU.
