Dry Pack Grout is a high-strength, non-shrink structural grout designed for demanding applications where traditional flowable grouts cannot be used. This natural aggregate-based formulation requires minimal water content, creating a damp pack consistency that delivers exceptional cohesion and bearing capacity. Engineered for structural baseplates, equipment installations, and precast element grouting, it provides reliable long-term support without the shrinkage issues common in standard grouts.
With compressive strengths reaching 7,000 psi at 28 days and progressive strength gain from 2,500 psi at 24 hours, Dry Pack Grout ensures immediate stability and long-term performance. Its unique formulation contains no chloride-based or corrosive ingredients, making it safe for use around reinforcing steel and embedded hardware. The extremely cohesive nature at damp pack consistency allows for precise placement in confined spaces while maintaining structural integrity under load.

Key Features of Dry Pack Grout
- High Compressive Strength
Achieves 7,000 psi compressive strength at 28 days with progressive strength development from 2,500 psi at 24 hours. - Non-Shrink Formula
Engineered to maintain dimensional stability and provide long-term structural support without shrinkage-related failures. - Extremely Cohesive
Maintains excellent workability at damp pack consistency, preventing segregation during placement and compaction. - Chloride-Free Composition
Contains no chloride-based or corrosive ingredients, ensuring compatibility with reinforcing steel and metal components. - Natural Aggregate Base
Utilizes only natural aggregates for consistent performance and concrete-like appearance after curing. - Minimal Water Requirements
Designed for placement with minimum water content (0.55 to 0.70 gallons per 50 lb bag) for optimal strength development.
Recommended Applications for Dry Pack Grout
Dry Pack Grout is specifically formulated for contractors and engineers working on structural applications where high bearing capacity and dimensional stability are critical.

Frequently Asked Questions
What water content should be used with Dry Pack Grout?
Water content typically ranges from 0.55 to 0.70 gallons per 50 lb bag, depending on temperature and humidity conditions. Always use potable water and achieve a damp pack consistency.
How should Dry Pack Grout be placed?
Use a ramming device with a blunt end to pack the mixed grout with sharp, quick blows. Hammers or mallets can also be helpful. Build up material until the space is completely filled.
What mixing equipment is required?
A mechanical mixer must be used when mixing Dry Pack Grout. Hand mixing is not recommended for achieving proper consistency and performance.
What is the shelf life of Dry Pack Grout?
Two years in original, unopened packaging when stored in a dry location.
Can admixtures be added to Dry Pack Grout?
No. Do not add admixtures or fluidifiers as they can compromise the product’s performance characteristics.
What are the temperature limitations for use?
Do not use at temperatures that may cause premature freezing. Keep grout from freezing until it reaches a minimum strength of 4,000 psi. Follow ACI 305R or 306R guidelines for hot or cold weather applications.
