You can apply a concrete waterproofer/sealer..... http://www.homedepot.com/b/Building-Materials-Concrete-Cement-Masonry-Concrete-Waterproofers-Foundation-Coatings/N-5yc1vZaq3z
I agree, you can seal it and make sure that its waterproof so the condensation won't seep through and affect the tiling
There is a under pad you place over the floor before you lay tile. It prevents sweating and helps the file float on top of the concrete.
