Sika® WT-220 PMY

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
