Does CML provide a barrier to corrosion, or can it prevent corrosion?
CML is the perfect way to prevent corrosion within cast iron pipes. The CML maintains an alkali surface on the cast iron (or ductile iron) pipe that effectively prevents corrosion for as long as the lining remains in the pipe. This is much better than providing a “barrier to corrosion” — that is, a coating system that works as a barrier and tries to prevent corrosion by keeping moisture from coming into contact with the pipe.
