Cold Expansion Joint

Owner's rep walks into meeting. She is a tilt up concrete engineer in silicon valley. SWEET. They all came to sences.

Now the rH..... See how dark that slab is. Testing came in from low 80's to 99%. I think the pH is like 12. UGH. So annoying.

For some reason with this one tester every time I get some super high test results. He uses putty to seal the wagner 'cap' to the sleeve / concrete. Might that throw results off?
