An electrician 'fixed' an issue by making this hole in a basement cinder block wall.

.. how do I put that box back in or fix the wall or something?

Inside the box are two capped (hot) wires.

The pipe seems to be copper. Doesn't bend or anything. It can't (at least easily) be pushed back in.

I had wanted to use cement paste.. but like what do I do about the box? I guess I could paste everything except the metal pipe but geez: then i still have this sketchy box hanging out.

Any ideas?
