Five Star Hybrid Grout, 45 lb Bag
Five Star Hybrid Grout is a high-performance, non-metallic, non-shrink cementitious specialty grout that delivers ultra-high early and ultimate compressive strengths along with superior bond performance. It can be placed across a wide temperature range (35°F to 100°F), achieves ≥95% effective bearing area, and maintains structural integrity at elevated service temperatures up to 600°F. The highly flowable formulation is suitable for both pouring and pumping under baseplates, tanks, and precast elements.
Key Features
- Ultra-high early strength: 5,000 psi at 8 hours and 7,500 psi at 1 day (72°F).
- 28-day compressive strength of 16,500 psi at 72°F.
- ≥95% Effective Bearing Area (ASTM C1339).
- Superior bond strength of 4,000 psi (ASTM C882).
- Highly flowable — pourable or pumpable.
- Non-shrink from time of placement.
- Service temperature capability up to 600°F (316°C).
- Very low chloride permeability.
Applications
- Precision alignment of machinery and equipment baseplates.
- High-load and low-vibration equipment installations.
- Seismic isolator and high-load anchor grouting.
- Tank and vessel support.
- Precast element connections requiring high early strength.
