Would someone 'splain REBAR to me, please?
What does, for example, #4 rebar indicate?
What size rebar should a larg-ish gunite pool be constructed with?
I see some reference to 'center measurement' when discussing rebar on this forum. What is that? What is best?
Should there be extra rebar in the bond beam?
Anything else, rebar related, I should be concerned with? Should I even be concerned about rebar at all????
Thanks in advance.
