Does concrete dissolve copper?
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.
How do you break concrete around copper pipe?
You will need to remove some concrete to access the pipe. You can use a concrete cutting saw or an electric jack hammer; both can be rented from tool rental companies. Concrete slabs are usually between 4 to 6 inches thick.
Does copper pipe corrode in concrete?
According to the Portland Cement Association the interaction of copper with both dry and wet concrete should not cause a corrosion concern.
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.

How long do copper water pipes last?
70 to 80 years
Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 45 years. In most new construction, this is seldom a problem, but if you live in an old home you might want to see what pipe material your house has.
