Flexcrete 851 Coating
Cementitious Coating 851 is designed for internal and external structural waterproofing of concrete and other mineral substrates. Cementitious Coating 851 resists positive and negative pressure under 100m head in water retaining and below ground structures as well as roofs and decks. It provides chloride protection on highway and coastal structures and enhances the durability of reinforced concrete by reinstating effective cover to achieve the specified design life.
