The Role of Coatings in Manhole Rehabilitation - …
Cementitious liners that use calcium aluminate cement rather than Portland cement maintain a higher pH level that is less affected by the corrosive gases in the sewer system. The higher pH level limits the growth of SOBs, thereby prolonging service life approximately four to five times* over that of typical Portland-based cements.
