METASEAL
Improves strength, density, and impermeability by reacting with free lime in the cement matrix. A calcined kaolin pozzolan formulated for high reactivity in strength- and durability-critical concrete.
How METASEAL Works
Fine Particles Fill the Matrix
Ultra-fine metakaolin particles disperse uniformly throughout the concrete mix, filling the spaces between cement grains and aggregates.
Reacts with Free Lime
Reactive alumina and silica combine with calcium hydroxide released during cement hydration, producing additional cementitious binding compounds.
Improves Strength & Impermeability
Newly formed hydration products refine the pore structure, increasing strength and density while reducing permeability throughout the concrete matrix.
Technical Specifications
Application Systems
High-Performance Concrete
Boosts compressive strength while reducing permeability, making it ideal for high-grade structural concrete mixes.
Impermeable Concrete Systems
Reduces water and chloride ingress in exposed and below-grade concrete structures, improving durability.
High-Strength Precast Elements
Supports demanding strength and density requirements for precast and prestressed concrete production.
Marine & Bridge Structures
Improves long-term durability in aggressive exposure environments, including marine, coastal and bridge applications.
