Cold Expansion Joint

RE: Cold Expansion Joint
The Wagner reads at the bottom of the hole. The sealing fins on the side of the barrel assure it is just reading from the bottom of the hole. Sealing the cap to the top of the barrel should have no impact on the sealed sensor.

Maybe your readings are always high because he drills straight through the cement into the ground below!

One thing I have always admired about testing with Wagner probes is they are so consistent. If you are reading between 80 and 90 I would look for an answer to that discrepancy.... Is the slab of uniform thickness and are the holes at uniform depth?
