Don't forget, it's much easier to break if you can undermine it (i.e.

If you can get underneath it then one good way of breaking up the
concrete block is to light a fire underneath, then sit back and wait.

That's one of the methods that they used in days gone by to bring down
the walls of a fortress - dig a hole beneath the castle wall, fill it
with firewood, set it alight, then have a party whilst the castle
dwellers shat themselves knowing what was going to happen.
