Title: in situ testing with existing floor covering.
Post by: wilcoxp on February 13, 2017, 08:36:41 PM

if i am going to perform in situ moisture testing in a slab that is currently covered with vct or any other floor covering for that matter, hasn't the moisture in the slab reached equilibrium, and if so, does it matter what depth the probe is installed? In other words, 40% depth on a slab drying from one side will give you potential equilibrium when the slab is covered, so what about testing a slab that is already covered and has been for some time?

In theory you may be correct, but we aren't sure how long actual equilibrium takes to transpire once flooring is installed.  That being said, you are always going to be safe to drill to the 40% depth in the situation like you speak.
