Questioning the results of RH probes

[CC Solutions]

Hi Brian, 'Others' here, glad to have you...

I have tested many slabs that were less than 75%, in fact just recently I was handed a job for mitigation and when I conducted my testing I found the slab was in the upper 60% range. Believe me, I wanted it to be higher and the owner was ready to pay me to mitigate this large facility, but the numbers were fine.

I know exactly what you are thinking and that's why you need to hear from those who do read low numbers, and I read them often.

One question that would explain your situation quite readily: You don't wet drill do you?
