Just remember, steel or mesh will not help prevent the slab from failing. It
will only hold the two separated pieces from the crack from falling, not

in the pour not cracking but as in our contracts the concrete itself is
"Guaranteed to Crack" when and where is the unknown. I have concrete pours
that have zero cracks after 13 years of being poured. I have some pours, few
thank goodness, that have cracks we are amazed as to why it cracked and how
the crack actually ran.
