just about to build a new freezer, 8m x 15m on the floor

(I build it, fridge engineer does fridge stuff)

I've done a few before, thats no problem

but every time I've taken a freezer down the floor panels have been soaking wet, thats with my freezers and a couple of others

so I was thinking maybe I should put some kind of mesh down (few mm thick?) so the floor can be allowed to... drain?

ok, the inside surface of the panels is -20'C, but the floor is above freezing, in the middle of the insulation will be halfway temp etc. etc.

worth it or is it a silly idea?

or was I just unlucky with the ones I've taken down, and they're not normally wet ?


concrete slab has under floor heating installed to stop ground freezing/heaving, water at 15'C, circulates 24/7
