Grain store floor sealing

[derbyshireben]

Evening all, considering the options for converting a former livestock shed to grain storage.
Panelled all round, roof in good order, floor has no DPM but is in good condition, pondering options, if any to seal/ prevent water ingress into stored grain through the concrete.
any suggestions?

I've got one similar grain always goes nosey on floor and against bottom of walls.
Can't be bothered. But reckon thick DPM and 4" concrete might cure it, so long as floor is solid and not cracked.

Okay cheers, it doesn’t go bad enough to spoil then? Maybe the way would be to run with it a year or so and see how I go…

I try not to put anything in there for more than 6-9 months. Shed was built when laying 50kg fert sacks under concrete "to save having to buy dpm sheet" was popular. It never gets wet, as such, just enough damp to ensure a 1" layer of nosey corn next to the concrete for about a foot out from the panel walling.
