NSG 60
High-Strength, Free Flow, Non-Shrink, Cementitious Precision Grout
hahne NSG60 is a single-component, ready-to-use, highperformance cementitious grout with controlled expansion. It is specially designed for precision grouting applications where superior strength, flow and dimensional stability are required. The formulation incorporates advanced German expansion chemistry and optimized Indian raw material technology to ensure consistent flow, non-shrink behaviour, and long-term durability.
- 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.
- 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.
