Efflorescence

[Ron Bishop]

I have never seen this much efflorescence accumulate on a garage slab. This is what accumulated just during the winter. There is a natural pond behind the structure, so the water table must be pretty high. Any thoughts as to why there is so much of this?

There was more than your average ammount of water in there

Possibly thought: 'This is just a garage, we don't need no stinkin' moisture barrier under it.' ;)

Ummm ... yeah, you do. :)
