Rheomac 725 

RHEOMAC 725 is an integral admixture designed to reduce the rate of transmission of moisture through concrete. It does not contain chemicals that might cause undesirable side effects when used in conjunction with admixtures normally used in concrete.

RHEOMAC 725, used as an integral admixture in concrete, reacts with the cement hydration process to form a hydrophobic coating on the pore and void surfaces of concrete, which reduces the capillary suction and minimises absorption and penetration of water.
