More Detailed Explanations
Double rod rebar chairs are very often used as rebar
supports. These are readily available at virtually all home
centers and lumber yards. This product is designed for
use in footings only, not slabs. That's because footings
are never walked in, rather walked along side. You see, in
order to place concrete within a slab, the workers must
walk on top of the rebar as they work the concrete into
place. This picture is exactly what happens to this product.
Broken bricks and other debris also are often used as
rebar supports also. The method has several problems.
First, the height is not consistent. Second, the rebar is not
secured to the broken brick allowing it to easily move
around or even fall off. Third, the irregular and pointed
shape of the base will likely poke a hole in the vapor
barrier. Finally, no engineer on earth would approve this
method. And neither should you.
This product, called a steel "high chair" is a product that's
made specifically for slabs also. However as you can see
here, it does not secure to the rebar and can be easily
tipped over. But here's the real problem. This product
is made of steel and so is rebar. What happens when two
different steel materials are permanently placed in contact
with each other? They will rust. This is why you will never
see this product in D.O.T. projects.
Plastic materials have been introduced in recent years as
an innovative material of choice for rebar supports. The
manufacturers of these products can make these for just
pennies each, meaning they make big profits on you. But
what do you get. A material that will melt when left in the
hot sun. Plastic becomes extremely brittle when left in the
cold. Also, plastic, at cheap prices, can only be made so
strong. Vinyl siding or Hardi-plank? Same kind of choice.
Here's the worst possible approach. Nothing used at all.
Many contractors say they will lift the rebar up into the wet
concrete as they go. Bologna. If the rebar starts out on
the ground, it will stay on the ground, guaranteed. Ask
anyone in foundation repair industry who has ever broken
up a failed slab where the rebar was found to be in the
slab. Using nothing is like throwing the money you spent
on the rebar right out the window! Avoid the temptation
to save a penny after spending all those dollars!

Did You Know? In order for a rebar support to work effectively, it must be able to withstand not only the weight of the rebar, but also the weight of the concrete and someone standing on top of it without the support crushing or cutting through the vapor barrier. Why? That's because the rebar WILL get stepped on during the pouring process. This is where other products fail and/or cause unintended consequences.
