  • Repair or replacement of concrete elements
  • For horizontal, vertical and overhead repairs

What are the unique features of MasterEmaco S 440CI?

  • 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
  • Only requires the addition of potable water

What are the benefits of MasterEmaco S 440CI?

  • High-early strength allows early form removal
