hmmm..if the unit has legs it will be raised above the pad
anyway and the effect of moisture from the pad is minimal..
as a matter of course I compact the earth, put plastic over
the earth, then gravel then pour the concrete...40' drive
survived many years in the snow and rain of the High Sierra
so your pad and unit should be ok...if the unit has no legs I
would put some the unit on an steel or Al frame to fit the
perimeter of the unit and may need central support? Don't know
your unit//

Subject: Re: [DIY] air cond. ground base?
We need to replace the foundation under a whole house outside air conditioning unit.
Home Depot doesn't sell these and we have learned that a concrete base may allow dampness to affect the unit.
Would a sheet of plastic under solid masonry pavers be good enough?
Any other suggestions?
