Five Star Hybrid Grout – 45 lb Bag
Five Star Hybrid Grout is a high-performance, cement-based precision grout engineered for heavy equipment support in critical load-bearing applications. With ultra-high early and ultimate compressive strengths, it delivers 95% effective bearing area and can be installed across a broad temperature range from 35°F to 100°F. Its non-shrink, highly flowable formulation makes it ideal for pumping or pouring under baseplates, tanks, and precast elements, while maintaining structural integrity even at elevated service temperatures up to 600°F.
Key Features:
- Ultra-high early and 28-day compressive strengths
- ≥95% effective bearing area (EBA)
- Highly flowable — pumpable or pourable consistency
- Non-shrink from time of placement
- Usable in cold and hot temperatures (35–100°F)
- Withstands continuous exposure up to 600°F (315°C)
- Formulated with air release technology to reduce voids
Applications:
- High-load machinery and static equipment bases
- Precast concrete and structural steel supports
- Tanks, vessels, pumps, and generators
- Low-vibration equipment installations
- Seismic isolator and high-load anchor grouting

Frequently Asked Questions:
What is the minimum installation temperature for Five Star Hybrid Grout?
Install at 35°F or above. Grout and substrate should be maintained above 40°F until 1,000 psi strength is reached.
Can this grout be used for pours greater than 6 inches deep?
Yes, but consult Five Star Technical Bulletin TB105 for aggregate extension guidelines.
Does it require wet curing?
Yes, wet cure for a minimum of 24 hours. If not using a curing compound, continue wet curing for 3 days total.
