I am going to have a 24' x 24' pad poured 4 " thick . Ground has been tamped and plastic put down with a gravel base over the plastic . Today I will finish the install of 1/2 " rebar in a 24 " spaced grid . What should I uses to " space " the rebar aprox. in the middle of the 4 " ? I know they make plastic spacers but it has also been suggested to use rocks/stones/bricks etc. for spacers . I think what I want is 1 1/2 " tall " , so either spacers that tall or bricks/stones that thick . What have you used ?
