RH Testing Thick Slabs

[CC Solutions]

Opening the surface will promote drying. Instead of taking about 4 years to dry, that slab could be dry in one year now if conditions are perfect!!!

The low CaCl readings on WET slabs are EXACTLY why 1869 was changed, and 90% of the reason the flooring industry is struggling now. Sure that glass finish is allowing very little vapor out, but the slab is a time bomb waiting to ruin some installer's life!
And I know it's not porous... What do the installation instructions say about installing over a non-porous substrate? Do installers follow those instructions? Not likely.

Low VOC adhesives are just part of the new issues we face. How about ginormous power trowel finishing machines???
