Q) Will my inspector pass these on the slab prep inspection?
A) Reblocs qualify as a Class 1 rebar support as specified by the Concrete Reinforcing
Steel Institute (C.R.S.I.) To the best of anyone's knowledge, including architects and
engineers I've consulted with, their are no code specific rules regarding rebar supports.
The only known authority to specify any rules governing the use of rebar supports is the
C.R.S.I. The C.R.S.I. issues a guide to rebar and rebar supports called "The Manual Of
Standard Practice." In this guide and specifically in chapter 3, section 3, you will find
examples, including pictures and written descriptions of known and prior approved rebar
supports. You will find ReBlocs, also known as pre-cast concrete cubes, shown on these
pages.
Now, if your inspector is closed minded, unfamiliar with the general concept and unwilling
to actually research his decision making process, then I suspect he would turn down just
about anything. But he or she has no grounds to do so. I've only had 2 situations where an
inspector held up a job over ReBlocs. By just stating the above paragraph the inspections
were approved.
Q) How close together should they be put to work effectively?
A) In our own practical experience and according to the C.R.S.I., every 4 feet in all
directions. This works out well if the rebar is on 2 foot centers; then every other
intersection is easy to figure out.
Q) My inspector will not allow broken bricks for rebar chairs? Will this pass even
in those areas?
A) I absolutely agree with the decision not to allow broken bricks or even full bricks as
rebar chairs. The C.R.S.I. makes no evaluations of broken or makeshift materials used as
rebar chairs. ReBlocs are manufactured pre-cast concrete cubes and have one of the
highest ratings as such.
Q) I have never seen these or heard of them being used?
A) Well, everything is new to someone at some point. If you were from California and had
poured concrete in that area, then you would surely know about pre-cast concrete cubes,
also commonly known as "doobies" (that's pronounced dough-bees, not doo-bees, I know
what you were thinking.) You see, where it's absolutely critical that foundations be extra
strong because of seismic concerns, pre-cast concrete cubes are the favorite choice.
Note: On Tuesday 12/5/06 on a television show called "Dirty Jobs" on the Discovery
Channel staring Mike Rowe, Mike was pouring a concrete slab and getting whipped by the
hose. At one point he fell down. The rebar did not move because it was sitting on a
pre-cast concrete cube. If you saw that show, you've seen a ReBloc.
Q) How are these better than my wire or steel type chairs I've been using for so
long?
Note: We developed ReBlocs because of steel and wire type products.
A) Plenty! I ask you, what happens when you step on them? You can't see where you are
stepping when the concrete covers the rebar, so you know when you step on them. They
smash down, right? That either bends the support to the point it's no longer useful allowing
the rebar to drop, or the steel chair presses into the sub-base causing a break in the
vapor barrier or at least a mis-aligning of the rebar from it's intended final position. There's
more. Whenever 2 dissimilar metals are placed together, there will be rusting. This will show
as orange stains in the finish of the concrete years later. And there is nothing you can do
about it once it happens. The C.R.S.I. gives uncoated wire and steel products a class 3
rating because they know what will happen in just a few years. ReBlocs are a class 1.
