    Thanks. Very helpful to know what chemicals should not be mixed together to damage concrete. As a homeowner this is useful information so that I don't accidentally erode my concrete foundation. I'll be sure that I store these common household chemicals apart from each other so they don't accidentally leak and mix

    Did it work? I imagine a few balloons won't do much, but let's hope they do. Or that the insurance company at least thinks they might have done some damage and forces the construction company to start over.
