I would be cautious....I poor lots of concrete. Most of the slabs are
engineered.
Many are not. The practice of using fiber mesh was tossed many years ago.
It had a failure rate.
Homeowners may like the ease of application but when you look into the
serious concrete poors and concrete made to last most if not all use re-bar
grids.......
Sub-grade is very important and water ratio to concrete is also a factor.
Anyway, that is the "norm" in Calif. and if you look at Bridges or any
commercial concrete work, you will see re=bar.
oh well.....jloomis
just my 2 peanuts....
