Sika® WT-220 PMY
Water Resisting and Crystalline Waterproofing Concrete Admixture
Sika® WT-220 PMY is a combined water resisting and crystalline waterproofing admixture used to reduce permeability of concrete.
Sika® WT-220 PMY consists of a mixture of cements, amino alcohols and some other active ingredients. These active materials will form non-soluble materials throughout the pore and capillary structure of the concrete and seal the concrete permanently against penetration of water and other liquids. In addition, the special formula and ingredients enhances the self-healing properties of concrete and will improve the ability to heal concrete cracks
- Reduced water penetration under pressure
- Reduced water absorption
- Enhancement of self-healing properties of the concrete
