| Side view of rebar running in one
direction. The rebar running perpendicular to the rebar shown in the
picture has not been installed yet. You can see the rebar's have been
tied but do not have any blocks underneath them yet. The blocks are used
for spacers to keep the rebar off of the sand.
When you install the next section of rebar you will use the blocks to
tie the next layer of rebar together where they intersect. The blocks
are referred to as adobes and can be purchased at most home improvement
centers.
