    For predictable in-place concrete properties underwater

    This patented anti-washout admixture is specially developed for underwater concrete applications. 

    • Offers superior resistance to washout of cement and fines
    • Impedes the blending of external water into the plastic concrete
    • Reduces segregation, even with highly fluid, high water-to-cementitious materials ratio concrete mixtures

    The anti-washout admixture from Master Builders Solutions meets the requirements of the U.S. Army Corps of Engineers CRD-C 661-06, Specification for Anti-Washout Admixtures for Concrete.
