I have been a plumber for over ten years and I am certified as journey level in wash and ore as well as a master in wy. trust me you can insulate copper with foam or fiberglass,if your somewere that it gets below zero put heat tape on the pipe before you insulate. as for the concrete if they did it right it should have a sleave or protective wrap. copper pipe should never be in direct imobilizing contact with concrete.
I hope this helps
