The problem with concreting in pavers is the freeze-thaw cycle up here.
Even when the concrete is thick enough and reinforced and there are
expansion joints, the freeze-thaw cycle sometimes rears its ugly head
and large chunks of the paved area rise up or drop down. If pavers on a
bed of sand move, it is easy to reposition them.
Wrong, spoofer! You only have to worry about that when the concrete is
separating conditioned space to unconditioned space. Why? Well, if you
right wing turds new anything, you'd know that the freeze/thaw cycle
will move everything equally. Look at your sidewalk as an example. It's
certainly not founded below frost depth.
