CALCOAT® RG is a calcium aluminate-based cement specially designed for use in sewage systems. Its high content in alumina and the nature of the hydrates that are produced provide excellent resistance to corrosion from biogenic acids.


CALCOAT® RG concrete and mortar offer excellent resistance to abrasion, making them highly suitable for pipes, duct work and other sewage system applications.

Owing to its specific composition, CALCOAT® RG is easy to work with a long wet-edge time followed by rapid setting. The mortar and concrete rapidly achieve a very high mechanical performance level.

CALCOAT® RG concrete and mortar are used in sewage systems which are required to resist biogenic acid corrosion: the inside lining of ductile iron pipe, protective layers for concrete piping and "full mass" concrete piping.
