Concrete Hood Method

RE: Concrete Hood Method
Howdy all, I just found this site, so it may take a while to get to know everyone.

The hood method does not replace in-situ probes in any way. The hood will measure vapor being released from the slab in a manner similar to the CaCl test with one important difference. The Calcium Chloride can actually draw moisture from the slab, as proven by CTL labs when they placed a CaCl test on a stable slab (not emitting moisture at all) and the CaCl test showed 4 lbs emissions.

In-situ probes tell us the potential a slab has. Think of a slab that is extremely wet, perhaps wet cured for 4 months, then quickly dried with dehydrators, fans and heat. The top of the slab will dry rather quickly, and you could see great MVER readings from the top 1/4" - 1/2", but the amount of moisture available in the slab could be 98%.
