Plast-O-Proof is an integral waterproofing compound, ideal for use with both concrete and plasters. It is based on specialised surfactants and synthetic resin which impart superior flow and cohesive properties in concrete and mortars. Use of integral waterproofing compounds in concrete and mortar is one of the precautions taken to achieve a waterproof concrete or plaster.
Concrete and plasters admixed with this compound exhibit advantages like increased durability due to air entrainment, preventing segregation bleed and thereafter honeycombing, and improved surface finish of concrete and plaster. Additionally, attacks by sulphates and chlorides from ground water in coastal areas are well tolerated.
