WHAT ABOUT EXPANSION JOINTS, ARE THEY COVERED
UP?
Expansion joints or control
joints are necessary to prevent cracking of the
concrete. Concrete must be allowed to expand
and contract with temperature changes. These
joints provide a ‘controlled crack' for
this movement. All expansion joints are left
in place, we cannot cover them up. We also re-cut
all existing joints a little deeper to ensure
that when it does move, it moves where we want
it to and not at some undisclosed weak spot. next
