Admix C-500 12lbs Bag


Xypex is a unique chemical treatment for waterproofing, protection and improvement of concrete. Xypex Admix C-500 is added to the concrete mix at the time of batching. Xypex Admix C-500 consists of Portland cement, silica sand and various active, proprietary chemicals. These active chemicals react with moisture in fresh concrete and with the byproducts of cement hydration to cause a catalytic reaction. This reaction generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete that permanently seals the concrete and prevents the penetration of water and other liquids from any direction.
