SikaEmaco S 440CI

SikaEmaco® S 440CI is a high-performance, shrinkage-compensated, self-consolidating repair mortar engineered for large-volume structural concrete repairs. Designed for formed horizontal, vertical, and overhead repairs, this low-dust, polymer-modified formula offers high early strength, excellent bond durability, and integral corrosion protection for long-lasting repairs in demanding environments.

Featuring a dual expansion system, SikaEmaco® S 440CI compensates for shrinkage in both plastic and hardened states, while its low permeability helps protect against chloride intrusion and carbonation, extending the life of reinforced concrete structures.

Key Benefits of SikaEmaco® S 440CI:

• Low-dust formulation for safer, cleaner application
• Self-consolidating design eliminates the need for vibration
• Shrinkage-compensated for long-term durability
• Integral corrosion inhibitor protects reinforcing steel
• High early strength for fast form removal (2,500 psi in 1 day, 6,500 psi in 28 days, ASTM C 109)
• Excellent freeze/thaw resistance for cold and wet environments
• Flowable and pumpable for placement in congested areas
• Polymer-modified for improved adhesion and crack resistance
• Meets ASTM standards for structural concrete repair

Common Applications:

• Large-volume structural concrete repair
• Formed repairs in horizontal, vertical, and overhead applications
• Concrete element replacement in bridges, tunnels, and industrial facilities
• Infrastructure repairs exposed to freeze/thaw cycles
• Protection of reinforced concrete against corrosion and deterioration

💡 Available in 55 lb (25 kg) polyethylene-lined bags, with a 1-year shelf life when stored properly.
