RH Testing Thick Slabs

[CC Solutions]

You guys are so funny!

The slab will be wetter the deeper you go, because it dries out the top. So if you go full depth of the reader and it is too wet, then there's no point in going deeper!

Another thing you could do is core 4" hole down a few inches, remove that concrete, then place your probe at the 40% total depth.

But you guys already know.... It isn't going to be dry.... I've tested 14" slabs that were 3 years old that weren't dry yet.
