Five Star Hybrid Grout is a precision-grade, cement-based non-shrink grout engineered to deliver exceptional structural support in demanding industrial applications. Formulated with advanced air release technology, this ultra-high performance grout achieves superb flowability while reaching compressive strengths of 16,500 psi at 28 days, making it ideal for supporting heavy static load machinery, structural steel, and high-load infrastructure. With its ability to maintain 95% effective bearing area (EBA) and operate across a wide temperature range from 35°F to 100°F during installation, this grout extends your installation season and provides reliable performance in both cold and hot weather conditions.
This high-strength formulation provides consistent performance and long-term durability in environments where equipment is exposed to vibration, thermal cycling, or chemical exposure up to 600°F service temperature. Its excellent flowability allows it to easily fill tight clearances from ¾ inch to 6 inches beneath machine bases, sole plates, or structural supports, while its non-shrink characteristics ensure dimensional stability and alignment integrity over time. Ideal for fast-paced maintenance operations and critical equipment installations, Five Star Hybrid Grout simplifies placement while maintaining industry-grade mechanical performance under demanding loading conditions.

Frequently Asked Questions
What is the recommended placement depth for Five Star Hybrid Grout?
It is designed for placement depths from ¾ inch to 6 inches. For pours over 6 inches deep, consult Five Star Technical Bulletin TB105 for aggregate extension guidelines.
What mixing ratio should be used?
Mix with 3.3 to 3.6 quarts of potable water per 45 lb bag. Start with 3.3 quarts and add water as needed to achieve maximum flow without segregation.
How long before equipment can be loaded?
Maintain grout and substrate above 40°F until reaching 1,000 psi compressive strength. In-service operation may begin immediately after required strength is achieved.
What type of surface preparation is required?
Clean surfaces of oil, grease, and contaminants. Prepare concrete to coarse aggregate exposure with minimum ½ inch peak-to-valley profile. Presoak concrete surfaces for 8-24 hours to achieve saturated surface dry (SSD) condition.
Does it require special curing procedures?
Yes, wet cure with potable water for a minimum of 24 hours. If not using a curing compound, continue wet curing for an additional 48 hours (3 days total). Protect from freezing until 1,000 psi strength is reached.
What is the shelf life?
One year in original unopened packaging when stored in dry conditions. High relative humidity will reduce shelf life.
