If you have exposed steel, repair it quickly by cleaning and grouting the impacted location. <gallery mode="slideshow"> File:ES1.jpg|The Steel cylinder of this prestressed concrete cylinder conduit was visible in a recent inspection of this central montana da..."

When this occurs, the pipe will corrode faster on the outside than the inside. By inspecting the inside of the pipe, it may appear to be in good condition, however, the pipe may be brittle due to corrosion on the outside. <gallery mode="slideshow"> File:COF1.jpg|This picture s..."
