Description
Sika® 1 Waterproofing is a high-quality, chloride-free liquid admixture designed to permanently block water ingress in cement-based applications. When mixed with concrete or mortar, it reacts chemically to reduce capillary porosity, creating a dense and water-resistant structure.
Perfect for both new construction and repair projects, Sika® 1 is widely used in basements, water retaining structures, swimming pools, bathrooms, roofs, and external walls.
