penetrates concrete a few
inches - it is now ready to
make your next placement
of concrete.
Still later - 5/8" rebar
penetrates second lift
almost all the way into
second pour - better give it
a little more time to set up.
Still later - Again you

Sound Your Concrete
In order to know the firmness of
your concrete as you make each
lift (summer or winter), use a 5/8"
piece of rebar and SOUND YOUR
CONCRETE! As you push the rebar
down through your concrete,
you will be able to feel if your
previously placed concrete has
taken its initial set. This test will help
you to determine if the concrete
in your form is firm enough and
ready to support an additional
lift of concrete, without excessive
pressure on your form and form ties.
