SikaEmaco S 466 – Flowable, Shrinkage-Compensated Micro-Concrete for Structural Repairs (55 lb Bag) (Formerly MasterEmaco S 466)

SikaEmaco S 466 (formerly MasterEmaco S 466) is a one-component, shrinkage-compensated, flowable micro-concrete designed for structural-grade concrete repairs, grouting, void filling, and large-volume pour applications. It mixes with water only and produces a free-flowing, pumpable mortar ideal for columns, beams, pile tops, structural members, and places where conventional concrete is impractical.

This micro-concrete offers excellent bond to existing concrete or masonry, high early and ultimate strength, and enhanced durability properties including low permeability, chloride and sulfate resistance, and built-in corrosion protection. Its shrinkage-compensated formulation reduces drying shrinkage / cracking risk, making it suitable for full-depth repairs or structural reinstatement.

Benefits

• Flowable and pumpable — ideal for congested or hard-to-reach repairs and large volume pour applications
• Shrinkage-compensated and corrosion-inhibiting — reduces risk of cracking and protects embedded steel
• High early and ultimate compressive strength for structural integrity
• Low permeability, sulfate & chloride resistant — good durability in harsh / exposed environments
• Versatile application — suitable for interior or exterior, vertical or horizontal, full-depth structural repair or grouting
• Requires only the addition of potable water — simplifies jobsite logistics and mixing

Applications

• Structural concrete repairs — columns, beams, piers, parking garages, marine & tidal concrete, retaining structures
• Form-and-pour structural replacement where full-depth concrete is required but traditional cast-in-place is impractical
• Large-volume grouting under baseplates or embedded structural elements (piles, dowels, anchors)
• Repair of deteriorated concrete, void filling, re-profiling, pile tops, cast-in-place and precast applications
• Interior or exterior use, above- or below-grade, including cold / freeze-thaw exposed structures
