> Jack, this looks like a pretty good idea in the short term. But, every piece of concrete I have ever been associated with has been off-gassing water at a slow rate. I have stored wood face-down on concrete enough times that I should know better, and it has always been ruined - rotted - by constant exposure to that water off-gassing. The wood traps the water (which would normally have no problem evaporating, because it is a very slow rate) which then rots the wood. Now whenever I store wood flat, I put bricks or something between it and the concrete so there is an air-gap.

Even if there is, I would check pretty often around the bolt holes, because I think the bolts penetrated the barrier and the wood around the bolts will be rotten soon.

Yup, the first thing done to the concrete floor of my shop was to apply
a sealer, then a layer of mastic and vinyl tile. (tile, not sheet goods,
as it's simple to replace a damaged tile). It's held up well for almost
30 years, with no trace of moisture damage here in the soggy Pacific
The concrete walls were similarly isolated with a layer of 30 lb.
roofing telt, with an insulated stud wall and sheetrock over it.
