Though out of many installations, we never faced any probloems due to expaiosn joints in the cold store flooring, in one case since the RCC has shrunk a lite bit near the cold store doors, it had created lots of problems on the Bottom gaskets.

The Cold store is @ 60 x 40 x 12 M in size. There are Four doors , 2 on each side of 40 m side.

The Architech had no clue on this shrinkages & its effects. Are there any rules / logics on doing the expansions joints in the flooring?
