I was installing a twin socket in a brick wall and had cut / chiselled out

As I was drilling the remainder of the brick to hold the back box, the brick

back box!!http://i918.photobucket.com/albums/a...sa1/socket.jpg
Any suggestions?

Thanks

Could you use a "dry lining" box intended for plasterboard?
