This means you have to break the ice in compression. Compressive strength of ice is about 375 kPa (54 psi) just at freezing temp, and up to 1500 kPa (217 psi) at very cold temperatures. >> I have no tank experience but will offer the following. I assume that you cannot pour the water in the tank so that is a gap between the water and the wall! However, could you line the tank with a 2" - 3" (or whatever it needs to be) compressible material that is strong enough to resist the water pressure, but flexible enough to compress under the ice pressure? Just a thought. Bruce Resnick, SE Parker Resnick Str. Eng.
