Cement Mortar Lining Pipes

C&N’s Cement Mortar Lining process centrifugally applies pre-mixed cement mortar lining to the inside wall of the pipe, resulting in a smooth and hydraulically efficient surface.

Cement mortar lining can ensure a safe and abundant water supply for your water customers for many years to come. Cement will also extend the life of the pipe by inhibiting the corrosion of ferrous materials and preventing future rust and tuberculation formation.

Cement mortar lining: A history of quality

Did you know that the use of cement mortar as a protective lining for water pipes dates back to 1836 and that the first cement-lined pipes were installed in the United States in 1850? Many of these early cement mortar lined pipes have been in service for over 100 years and have shown no signs of tuberculation or corrosion.

Whilst the cement mortar lining process has undoubtedly improved over the years, history has proven that there is no other more reliable method of restoring capacity, eliminating leakage and preventing future tuberculation and corrosion in pipes than cement mortar lining.

Additional benefits of cement mortar lining include

• One-third to one-half the cost of new pipe installation, with cost savings increasing as pipe diameter increases.
• Permanently restores flow, seals joint leaks and pinholes, eliminates foul water complaints and restores adequate fire protection.
• Works with temporary above-ground bypass piping that uses water from other unaffected areas to provide uninterrupted water service to customers during projects.
• Replaces all valves and hydrants as with main installation work.
• Eliminates the need for extended road closures as access pits are dug every 500 to 600 feet rather than along the length of the project.
• A completed system will operate as efficiently and easily as a new main, but at a fraction of the cost.
• There is no need to replace the services to every house in the area, whereas in most cases you have to replace all the water services when working on a relay project. This is much more expensive and completely unnecessary when using cement mortar lining.

Pipes from 4″ to 160″ in diameter can be cement mortar lined. Cleaning and cement mortar lining can be carried out on all types of pipe, including cast iron, ductile iron, steel, corrugated metal and in both transmission and distribution mains.

Cement-mortar lining is more environmentally friendly than relay projects because, by using only access pits, we do not have to dispose of as much unsatisfactory dirt, crushed concrete and asphalt. We also do not need nearly as much select material to backfill the access holes as we do to backfill relay trenches. This also applies to the amount of new concrete and asphalt required for relay trenches once installation is complete, compared to the small amounts required to reconstruct access pits.

Cement Mortar Lining for Bridges

C&N also offers a cement mortar lining process for steel water mains used in new and refurbished bridges. We can provide the same process (with the same benefits) as above before the pipe joints are installed.
