The maximum uplift pressure in the u/s shall be counter balanced by the weight of water it self. Hence theoretically there is no requirement of floor thickness in u.s. but minimum floor thickness of 0.30 m should be provided.

The maximum uplift pressure in the u/s shall be counter balanced by the weight of water it self. Hence theoretically there is no requirement of floor thickness in u.s. but minimum floor thickness of 0.30 m should be provided.
