SikaControl® WT-200 P is a powder-based crystalline waterproofing admixture added directly into concrete during mixing. It reacts with moisture and unhydrated cement particles to form crystals that block capillary pores and micro-cracks, reducing water penetration.
This provides integral waterproofing, meaning the protection is built into the concrete rather than applied on the surface. It improves durability and helps prevent long-term leakage issues in structures exposed to water.
Suitable for:
-
Water tanks and reservoirs
-
Basements and underground structures
-
Foundations and retaining walls
-
Concrete exposed to groundwater or damp conditions
