Last year I had a my garage, driveway and sidewalk redone in concrete.
In the spring I noticed numerous cracks and the cement heaving near the
side of the house where the cement walkway was done.
After reading this group and various other sites on the internet, I
think the problem may be related to lack of expansion material along
the solid house structure.
The contractor just poured the concrete right against the foundation
without any expansion material, same with drainage pipes, electrical
and any other object.
I would like to know if it is code or just good practice to separate
large slabs from the foundation. I know It can damage the concrete, but
could it also crack my foundation.
