Cracks in concrete really. In El Paso I can look at almost any large commercial job supermarkets etc and see expansion joints or saw cuts were most look like the floors has the mumps. Along with adhesive that has emulsified especial black asphalt adhesive. Gypsum patch instead of cement based floor patch always evident.
If ever there is a need for concrete testing this is the proof. Must take some pictures sometime.
Had a high school 225,000 sf architect specified insuti testing flooring contractor didn't figure any monies for that so they are still going around and around about. Humm wonder who will win.
You got to love this one supermarket a local store hired some real low priced installers to install vct. I was called to see why the adhesive kept oozing out from the cracks. They used carpet adhesive!! Needless to say the entire job had to be redone.
Must stop this now being on the border with Mexico we get a lot of top notch installs and the horror stories abound.
