Xypex Admix C-1000 NF

Unique chemical treatment for the waterproofing, protection and improvement of concrete.


Xypex is a unique chemical treatment for waterproofing, protecting, and improving concrete. XYPEX ADMIX C-1000 NF is added to the concrete mix at the time of batching. Xypex Admix C-1000 NF consists of Portland cement and various active, proprietary chemicals. These active chemicals react with the moisture in fresh concrete and with the by-products 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.

NOTE: The Xypex Admix C-Series has been specially formulated to meet varying project and temperature conditions. Xypex Admix C-1000 NF is designed for concrete, where normal to a mild retarded set is desired. See Setting Time and Strength for more details. Consult with a Xypex Technical Representative for the most appropriate Xypex Admix for your project.


Xypex Admix C-1000 NF complies with the requirements of AS 1478.1, as a type SN Special Purpose Admixture.
