CONCRETE PAD

[pat32rf]

We used to pour a 6" floating pad with a thicker perimeter section. If I remember right the perimeter was about 18" wide and about 6-8" thicker than the rest(with rebar in the perimeter). We used fiberglass reinforced concrete and made sure we had good drainage underneath. We also made sure that the slab did not stick out too far past the walls so we could flash it to prevent water entry. That was a while back however, codes change but the ones we built seem to be still OK

When a pole building is erected and a concrete floor added later, no under frost foundation is considered. Why? The water could get under somehow.too........????????
I"ve read somewhere asome time ago, that a frost is not an issue under the roof or under any overhead cover. Is it true??
Is it the water I suppose , that destroys the slab? How and why, and why a concrete floor is spared?

Sorry for this stupid post from a heating guy. I remodeled my previous house completely, I never built anything on a concrete slab, or anything serious outside....shed doesn't count.

The only difference /major I understand/ between a floor in a pole building and a slab is that floor doesn't SUPPORT the structure /already erected /.The slab does. BUT,
The concrete is under the roof in either case.
Moisture can get under the slab just like under the floor.
So what's the deal???????? Anybody knows//.
Thanks,
