Bad, Bad Testing

[CC Solutions]

Frustrating isn't it Jim?

It's a wonder how anything stays down sometimes.

I had a job once that just about every conceivable installation failure happened. Improper prep, WAY too wet slab, improper trowel size, improper patch mixing, improper glue set times, improper temperature during install, I couldn't find anything that seemed to be done right, yet for the most part the floor was holding.

It held for quite a few years! Then when it let go, what a mess.

Oh, and not to be picky, but we are on a site dedicated to concrete moisture issues, so here goes:

You started off saying "Question 1 what was the mc of the concrete?" and that would be difficult to assess and require lab testing...

I think you meant to say "what is the relative humidity of the concrete".

Correct me if I'm wrong. We could have a looonnnggg discussion on the difference between moisture content and relative humidity and even moisture emission. In fact sometimes we do!
