How strong is 4 inches of concrete?
Typically we like to limit the weight to about 40 lb/sqft on an unknown 4″ slab. In most cases you can go to 80 lb/sqft in isolated spots, but unless you know roughly what the soil bearing and reinforcing is for that slab you might be looking at cracking.
Do you need wire mesh for 4 inch slab?
No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist cracking. However, not every piece of concrete necessarily requires that extra boost.
Is wire mesh better than rebar?
