So my friend had her floor done and within 5 months a huge hill in the middle of her living room had appeared. Being that I have flooring knowledge & exp she called me in to investigate, I obviously had to relive the tension and went straight to the CC test.

Here are the results:

8.8lbs
Ph strip showed 7 which is "ok" according to this specific test. i only did one spot (where the hill was)

Now this is pretty damn high if you ask me (maybe not, considering I have never had a reading this high) , can I get some ideas of what this could mean? could this be a larger problem then just normal? Can i just seal it it and lace and glue in some new flooring? or is this serious enough to warrant further professional help? I would appreciate any help and advice.

Did you grind off the adhesive to bare concrete when you did the test? You should have had a higher number on the ph test if you did. Uncontaminated conrete should read 9 - 13.

Is there a moisture retarder system under it besides the adhesive? Ad what type/brand of adhesive?

Aye, the floor was scuffed with a grinder prior to the test. Looks like Bostik Best was used and no sealer prior to the installation.

Still, your ph number says it was not "scuffed" good enough. It be to low.
