SCP 327 Time of Placement is a non-VOC, pre-mixed, spray-applied treatment that penetrates Portland cement concrete substrates at the time of placement.
SCP 327 controls moisture movement by penetrating the capillaries and voids left in concrete as bleed water exits. Once in the concrete, SCP products react with available alkalis to primarily form Calcium Silicate Hydrate (C-S-H). This reaction is the same as that of cement hydration that provides most of concrete’s desirable properties. These reaction products that are formed fill capillaries and shut down liquid water movement and reduce water vapour transmission to acceptable levels for coatings, coverings and flooring. This action makes SCP products an effective waterproofing agent – even under hydrostatic pressure.
SCP 327 is a one-time spray-on treatment that penetrates, providing permanent waterproofing and protection. It withstands hydrostatic pressure and can be effectively applied on the positive or negative sides of concrete structures. Minimum site disruption enables early access for trades.
Spray-Lock Concrete Protection® technology is unique with over 40-years proven performance.
