RH Testing Thick Slabs

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.

The standard says what it says. How wet is to wet when trying to figure out how fast it is drying, or predict it? Of course if it is 100% then your right, but still, standards are standards.

Having enourmous amounts of open space below the sensor is much like having open space above the sensor., which I believe is one reason they updated 2170.
If that were the case then I could simply test at one half and inch and save some drill bit time.
