Sika WT 200 — crystalline waterproofing material for concrete structures
Sika WT 200 is a premium crystalline waterproofing material from Sika India Pvt. Ltd. — a cement-based, integral waterproofing admixture that is added directly into fresh concrete during mixing to provide permanent, deep-penetrating waterproof protection from within.
Once introduced into the concrete mix, Sika WT 200's active crystalline chemicals react with water and cement hydration products to form insoluble crystals that permanently block capillary pores, micro-cracks, and voids — making it a highly effective waterproofing chemical for water-retaining and below-grade structures. Its self-sealing crystalline action reactivates whenever moisture is present, delivering lifelong protection that strengthens over time.
Widely used for water tanks, basements, swimming pools, tunnels, retaining walls, and foundation slabs, Sika WT 200 ensures strong reliability, user-friendly application, and consistent on-site performance — a trusted construction chemical from Sika India preferred by applicators and contractors for its proven long-term durability and effectiveness in demanding waterproofing chemical applications.
