Hello,
Here in the Pacific NW, it gets pretty wet and rainy this time of year. Iv'e had problem with humdity in the shop - for example, I'd go out and the whole slab would be wet. At one point I thought this was coming up through the slab itself. However, I tried covering a portion with some 6 mil poly, and that portion stayed dry. So it was not coming up through the slab - instead, it was humidity in the shop condensing on a cold slab that was below the dew point temperature.
I finally isolated the problem to rain water coming under the garage-type door, especially when wind driven. Even though the door bottom had the normal weatherstripping, that wasn't cutting it.
I found this product in one of those catalogs that they put in airplanes: http://www.jnkproducts.com/storm-shield-garage-door-threshold.htm It glues to the slab and really works to keep the rain out. Amazon has it for a better price than the manufacturer's site ($39.94 for the 16'). Right now it's too wet and cold for me to glue it to the slab, but even just having it in place without the glue, it's doing the job.
