Oooo Ooooo, Me Me Let me answer that one!!
It depends on how 'knowledgable' the players are.
If they are completely oblivious to the moisture-in-concrete phenomenon, whoever brought it up is the bad guy. If the flooring installer is about to install and he tests the slab before he starts and finds it's too wet, everything is his fault!
If everyone is knowledgable and familiar with the issue, nobody is really the bad guy, but some fingers will be pointed at anyone who sealed the floor, gave it a burned (sealing) finish, or let it continue to get wet for months.
Then you have the 'other' testers.... The ones you call when the flooring guy or the GC or independent tester tells you the floor is too wet... These 'other testers' always come in with test results that are just below maximum so the job can continue... I'm serious! I've had GC's call other companies in, they test the same floors I tested and found WAY wet, like 95%, and their tests will come in at 79% if the flooring requires a maximum of 80%.
And in the areas where the maximum is 75%, they test it at 74%.
I have gone back to jobs and been surprised the flooring is going down, only to be told that 'XYZ Engineering' was called to test and the floor passed everywhere....
This happens all the time folks. XYZ gets tons of business because they always have good news and never hold up a job!
When the floor fails, new testing takes place, and who knows why it is wet now, but XYZ swears it was good before it was installed. Then they point to other failures where there were good readings and the moisture changed later (sound familiar???? CaCl!!!!) and they bow out of the repairs.
Somehow we have to hold these testing companies' feet to the fire and make them responsible for solid testing. Certification is NOT enough. Anyone can get certified and then conduct poor testing to bring in the easy money.
This is also why I suggest everyone do some testing. I'm not going to install a million dollar floor without dropping a few Wagners in it, I don't care how many 'experts' tell me they tested it 1000 times perfectly. A couple Wagners are CHEAP compared to $25 per square foot replacement costs....
And don't think for a minute when a floor fails that everyone just figures out who's fault it is and they shake hands and someone (not you) pays for it. Everyone gets called in, everyone meets to look at the floor, everyone has travel expenses and repair expenses and testing costs and many times everyone shares in the repair.
Put your own Wagners in on every job to double check no matter what anyone tells you.... That is golden advice worth a fortune right there.
