| Here's a good example of properly
tied rebar. Most engineers require a rebar to lap no less than 40 times
the diameter of the rebar itself. An example of this would be if you
have number four or half-inch rebar the diameter of this rebar will be
one half of an inch thick. So if we multiply 40 times one half this will
give as 20 inches. The lap should be no less than 20 inches from the end
of one piece of rebar to the other end of another piece of rebar.
