A Revolutionary Technology Is Invented

Spray-Lock Concrete Protection (SCP) spray-applied technologies are made up of post-initial set applied colloidal silica. Because of the colloidal silica’s extremely small particle size, it has a tremendous amount of pozzolanic potential, greater even than un-densified silica fume. This reaction takes place in the capillary voids and pore space in concrete, filling the void space with Calcium Silicate Hydrate or C-S-H, the same reaction product concrete relies on for most of its strength and durability.

Spraylock Africa is the African distributor for Spraylock Concrete Protection (SCP) and Spraylock Adhesives, which are based in Chattanooga, Tennessee, USA, and led by Fred Land.

Located in Johannesburg, Gauteng, South Africa, Spraylock Africa is headed by Carl White.

His team continues to stand by SCP solutions, which are built upon unique technology with a more than 35-year-long track record in the market, as well as a team of experienced and skilled people who are passionate about and dedicated to solving their clients’ unique concrete challenges.
