Since 1976 AP/M has helped cities, engineers and contractors select the best tool for each different manhole problem with its PERMACAST® system of structural cement liners, coatings, structural polymers, cured-in-place liners, chimney seals, channel liners, and more! In 1996, it introduced its ConmicShield® additive for long term, internal corrosion protection of concrete. Since it is added during mixing, it is not a surface treatment that can wear off or delaminate! Now CentriPipe® is available for trenchless, structural lining of large diameter culverts and sanitary pipe. All technologies, equipment and materials are offered exclusively through its network of contractors and cities throughout the World.
