  • High-strength non-shrinkage grout is a dry powder building material compounded with high-quality cement, selected aggregates and functional admixtures. It features excellent self-leveling performance, early strength, high compressive strength, micro-expansion, zero shrinkage and good anti-segregation property.

  • After mixing with water, it owns superior fluidity to fill gaps automatically and densely. It keeps stable volume after hardening, with firm bonding, good aging resistance, corrosion resistance and impact resistance.

  • Easy to construct and fast strength development ensures rapid reaching design strength, realizing dense filling, reliable anchoring and accurate leveling.
