Product Description

BOSTIK CWP is a surface applied, integral crystalline waterproofing material, which waterproofs and protects concrete in depth. It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. Bostik CWP needs water only to be mixed prior to the application. When Bostik CWP is applied to a concrete surface the active chemicals combine with the free lime and moisture present in the capillary tracts of the concrete to form an insoluble, crystalline structure. These crystals fill the pores and minor shrinkage cracks in the concrete to prevent any further ingress, still allowing the concrete to breath.
