Nisiwa-SH
Nisiwa-SH is a single-component, hydrophobic silane-siloxane impregnation treatment for concrete, masonry, and natural stone surfaces. Penetrating deep into the surface pores, it reacts with the substrate to create a hydrophobic lining that repels liquid water while remaining permeable to water vapour - protecting the structure from chloride ingress, freeze-thaw damage, efflorescence, and staining without affecting the visual appearance of the surface.
Unlike coatings that sit on the surface and can peel or discolour, Nisiwa-SH works below the surface and is invisible once dry - making it the preferred protection treatment for architectural concrete, natural stone facades, heritage masonry, and exposed infrastructure.
Key Features
- Penetrating silane-siloxane - invisible, subsurface protection
- Repels water and chloride while remaining vapour-permeable
- Prevents chloride-induced corrosion in reinforced concrete
- Reduces freeze-thaw and efflorescence damage
- Does not alter the colour or texture of the substrate
- Long-lasting protection (10+ years on well-applied surfaces)
Available from Technotrade Associates. Used on bridges, marine structures, facades, and heritage buildings across India.
