High-Strength, Free Flow, Non-Shrink, Cementitious Precision Grout
A high-strength cementitious grout designed for precision grouting applications such as base plates, machinery foundations and structural anchoring. The grout provides excellent flowability, non-shrink properties and high early and ultimate strength.
Features and Benefits
- Non-shrink and dimensionally stable – controlled expansion compensates for shrinkage.
- High early and ultimate strength for rapid commissioning.
- Excellent flowability ensures full contact under base plates.
- Pre-packed and chloride-free, ensuring consistent performance.
- Dual expansion system for both plastic and hardened states.
- No metallic content – prevents staining and corrosion.
- Compatible with pump or manual placement.
- Resists oil, vibration, and impact.
Area of Applications
- Grouting of base plates for heavy machinery, turbines, compressors, and pumps.
- Grouting under precast elements, bridge bearings, and stanchion base plates.
- Filling of bolt pockets, anchor sleeves, and structural voids.
- Suitable for static and dynamic load-bearing applications.
- Precision grouting of structural supports and columns.
- Tie-rod hole filling for concrete structures.
