SikaEmaco 440 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" to full depth.
SikaEmaco 440 is a high-performance, one-component repair mortar designed for large-volume, structural concrete repair. This self-consolidating, low-dust, shrinkage-compensated mortar offers excellent flowability and can be pumped or poured into congested areas without vibration, minimizing honeycombing. Ideal for both formed horizontal and vertical repairs, it achieves high early and ultimate strengths and provides long-term durability with superior freeze-thaw stability, chloride resistance, and low permeability. SikaEmaco 440 is suited for structural replacement or repair of deteriorated concrete in both interior and exterior applications, with placement thicknesses ranging from 1.5 inches to full depth.
