Unisorb Unisorb V-1

Key Features of Unisorb V-1 Premium Non-Shrink Grout

Exceptional Compressive Strength
Develops up to 11,875 psi at 28 days, with early strength exceeding 6,500 psi in 24 hours for faster equipment startup.

Controlled Expansion Technology
Proprietary expansion mechanism eliminates shrinkage and ensures positive contact with all surfaces during initial mixing and plastic set stages.

Superior Flow Characteristics
Highly flowable consistency allows pumping and vibration for complete filling of complex base plate configurations and anchor bolt patterns.

High Temperature Performance
Maintains structural integrity at service temperatures up to 1000°F, with minimal strength reduction at elevated temperatures.

Versatile Installation Methods
Can be poured, pumped, or vibrated depending on application requirements and site conditions.

ASTM C-1107 Compliance
Exceeds all requirements of ASTM C-1107 for non-shrink grout performance and long-term dimensional stability.

  • High-load applications requiring superior bearing strength and stability

Frequently Asked Questions

What section thickness range is recommended for V-1 Premium Non-Shrink Grout?
The minimum section thickness is 1 inch, with a maximum range of 2-3 inches without aggregate extension. For larger sections, V-1 can be extended with 50% pea gravel by weight.

How quickly does V-1 develop usable strength?
V-1 reaches over 4,200 psi in 24 hours and continues developing strength to 11,875 psi at 28 days. The ASTM C-1107 requirement of 5,000 psi is achieved in just 3 days, even at maximum water content.

What is the working time and set schedule?
Initial set occurs at approximately 5-6 hours, with final set at 6-7 hours depending on water content and ambient conditions. Working time allows for proper placement and finishing.

Can V-1 be used in high-temperature applications?
Yes, V-1 maintains excellent performance at continuous service temperatures up to 1000°F, with compressive strength remaining above 8,400 psi even at maximum service temperature.

What water-to-grout ratios are recommended?
V-1 can be mixed at various consistencies from plastic (3.67 quarts per 48 lb bag) to fluid (4.32 quarts per 48 lb bag) depending on application requirements while maintaining ASTM C-1107 compliance.

Does V-1 qualify for sustainable construction credits?
Yes, Unisorb V-1 Premium Non-Shrink Grout qualifies for 3 LEED points, supporting green building certification requirements.
