How Does it Work?

The treatment strengthens the top 0.5-1 cm of the concrete through converting the unreacted calcium oxide to the cement binder (Calcium Silicate Hydrate or C-S-H) and blocks water and ions from penetrating into the concrete by:

  • Filling the pores and decreasing the porosity: Reaction of Silica Nanoparticles with Calcium oxide

  • Rendering the surface water repellent: Reacting the silicates in concrete with a Silane

This significantly reduces the likelihood and rate of weathering damage leading to cracking, delamination and formation of holes.
