There is a special "mud" utility box made for these applications. A hole is
made for the box to fit in, the conduit attached to the box and the CMU's
blocked around the conduit or the conduit is run down the holes in the block
to the mud box location. Then the box is grouted in place. The conduit
sticking out the top of the CMU is attached to a junction box and from there
you continue on with the appropriate wiring.
