Permeability Reducing Admixture for Hydrostatic
conditions (PRAH)
Zero VOC – PENETRON powdered products contain
zero volatile organic compounds and are safe for use
both outdoors and in confined indoor spaces
Exceeds requirements of ASTM C494-S (Specific
Performance Admixtures)


PENETRON ADMIX® (integral crystalline waterproofing admix) is added to the concrete mix at the time of batching. PENETRON ADMIX® 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, which generates a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete. Thus, the concrete becomes permanently sealed against the penetration of water or liquids from any direction. The concrete is also protected from deterioration due to harsh environmental conditions.PENETRON ADMIX® has been specially formulated to meet varying project and temperature conditions (see Setting time and strength). Consult with a Penetron technical representative for additional detailed support on your project.
