Underground Waterproofing System

Waterproofing and Crystalline-Based Concrete Admixture

Sika® WT-200 P is a waterproofing admixture that functions through both water-resistance and crystalline-forming mechanisms. It is used to reduce the permeability of concrete and enhance its self-healing capabilities.

Sika® WT-200 P contains a blend of active ingredients that generate insoluble compounds throughout the pores and capillary structure of the concrete, permanently sealing it against the ingress of water and other liquids. Furthermore, the unique formulation and composition of Sika® WT-200 P bolster the concrete’s self-healing properties, improving its ability to seal cracks.
