Euco Rock is a pourable hydraulic cement designed for anchoring and grouting applications where fast set times and high early strength are essential. This rapid-setting flowable grout sets quickly and achieves load-bearing and bond strength properties in hours rather than days, making it ideal for projects with tight schedules. Engineered without metallic aggregate or chloride ions, it provides excellent freeze/thaw durability and controlled setting characteristics for both interior and exterior applications.
This high-performance grout reaches 4,000 psi compressive strength in just 24 hours and continues to gain strength, achieving 7,000 psi at 28 days. With a working time of 5-15 minutes and initial set in 16 minutes, contractors can complete anchoring projects efficiently while maintaining structural integrity. Its flowable consistency allows for easy placement in tight spaces, and the product can be extended with pea gravel for larger area applications without compromising performance.

Key Features of Euco Rock
- Fast and Controlled Set
Initial set in 16 minutes with final set in 21 minutes, allowing for rapid project completion and reduced downtime. - High Early Strengths
Achieves 2,000 psi in 3 hours, 4,000 psi in 24 hours, and continues gaining strength to 7,000 psi at 28 days. - Excellent Freeze/Thaw Durability
Engineered to withstand harsh weather conditions, making it suitable for both interior and exterior applications. - Superior Flowability
Reaches endplate in 22.5 seconds during flow testing, ensuring complete fill around anchors and in tight spaces. - Non-Shrink Properties
Minimal height change (0.050% at 28 days) maintains anchor integrity and prevents loosening over time. - High Bond Strength
Slant shear bond strength of 2,100 psi at 28 days ensures reliable connection between grout and substrate.
