Can copper pipes come in contact with concrete?

A: Copper is unlikely to react with the limestone or concrete, as long as it isn’t too alkaline. The hard water deposits that sometimes build up in copper pipes are made up mostly of calcium carbonate, just like limestone. However, it might still be a good idea to run the copper through a PVC sleeve.

Does copper pipe corrode in concrete?

A: According to petrographer Bernie Erlin, copper won’t corrode in concrete unless soluble chlorides are present. When copper is adjacent to steel reinforcement, and an electrolyte such as chloride is present, steel corrosion is likely to occur due to galvanic action.
