This was my biggest mistake, not insisting on them using a bonding agent.
My new rule to live by is that any topping concrete under 4" is to bonding
agent before concrete is laid.  Oh well, you live and learn, If I had all of
the answers I'd be making a hell of a lot more money then I do now.  The
repour areas where I insisted that they bonded the existing slab are
wonderful.

It was kind of a hoot to watch the 'crete boys try to set their 2x4's for
edges.  The concrete floor is fairly old, in the neighborhood of about 60
years.  They tried to pin their wood down with #3 loads in their ramsets,
the concrete was so hard the pins were bouncing all over the place.  They
went back to their truck and grabbed the #5 loads and were only able to
shoot the pins about 1/2 way in.
