Surface-applied cementitious waterproofing by crystallisation




VOLSEAL 200 is a surface applied material, which waterproofs and protects concrete in-depth. It consists of grey Portland cement, specially treated quartz sand and a compound of active chemicals.  VOLSEAL 200 is supplied in powder form in 25kg tubs, and needs only to be mixed with water prior to application.


VOLSEAL 200 is designed to penetrate into the pores of concrete by capillary action and is channelled into the concrete by moisture. Once the crystals have formed, they remain permanent and block the passage of water through the pores of the concrete.
