How long have Cement Lined Pipes been used?
Beginning in the 1800s, cement mortar was found to have excellent anti-corrosive properties for use in water lines. At first, man entry size pipelines were rehabilitated using hand-lining techniques. Eventually, lining machines were developed which allowed for a consistent lining thickness on the pipe wall for both man entry and small diameter pipe. Since then cement mortar lining has been used around the world for new pipe and to rehabilitate old lines.
