    How does MasterEmaco S 440CI work?

    MasterEmaco S 440CI is a low dust, one-component, shrinkage-compensated, self-consolidating repair mortar.  It is designed for large volume repairs, including structural elements in applications from 1.5" (38 mm) to full depth.

    • Dual expansion system compensates for shrinkage in plastic and hardened states
    • Low permeability protects against carbon dioxide and chloride intrusion
    • Excellent freeze/thaw resistance for durability in cold, wet environments
    • Self-consolidation minimizes honeycombing without vibration
    • Very low chloride permeability and an integral corrosion inhibitor protects reinforcing steel
