ConmicShield is an EPA-registered, liquid admixture that prevents MIC corrosion in combined and sanitary concrete tunnels and other structures. Dosed directly into the concrete or mortar during the shotcrete, gunite, poured-in-place and precast processes, it is not a surface treatment or coating that can wear off, wash off, delaminate or peel. It is an integral component of the concrete added during mixing, providing protection throughout the entire thickness at a low cost.
