Five Star DP Epoxy Grout Pump Grade (PG) stands as the only pumpable, expansive, non-shrink, low exothermic epoxy grout specifically engineered for large volume machinery grouting applications. This versatile, dual-purpose system delivers exceptional performance in single, high-volume placements. Additionally, it maintains the precision required for critical equipment alignment. As a three-component, 100% solids, solvent-free formulation, it provides superior creep resistance combined with the highest effective bearing area. Consequently, this ensures long-term structural integrity under demanding operational conditions.
Contractors and engineers who demand reliability in challenging industrial environments will find this precision grout exhibits positive expansion per ASTM C827 testing. Furthermore, it maintains excellent flowability for depths as thin as ½ inch. The low exothermic properties prevent thermal damage during curing. Meanwhile, the extended 75-minute working time at 70°F allows for proper placement of large volumes without rushing. With its ability to achieve 95% effective bearing area and compressive strengths reaching 14,500 psi when post-cured, this grout delivers the mechanical performance required for rotating equipment, chemical processing facilities, and precision manufacturing operations.

Key Features of Five Star DP Epoxy Grout PG
- Pumpable Design
The unique formulation allows for efficient pumping through standard equipment. This enables precise placement in large volume applications and hard-to-reach areas. - Low Exothermic Properties
Controlled heat generation during curing prevents thermal stress and cracking. Therefore, it proves ideal for sensitive equipment and large mass placements. - Extended Working Time
The 75-minute working time at 70°F provides ample opportunity for proper mixing, placement, and finishing of large volume pours. - Superior Creep Resistance
Exceptional dimensional stability under sustained loading occurs with creep values of only 4.5 x 10⁻³ in/in at 400 psi and 140°F over one year. - Expansive, Non-Shrink Formula
The grout exhibits positive expansion per ASTM C827. As a result, it ensures tight contact with substrates and eliminates settlement gaps. - 95% Effective Bearing Area
Consistently achieves maximum load transfer efficiency when proper grouting procedures are followed. - High Temperature Service
Maintains structural integrity at continuous operating temperatures up to 180°F (82°C). - Excellent Chemical Resistance
Withstands aggressive chemical environments including acids, bases, and industrial solvents.

Frequently Asked Questions
What is the recommended placement depth for Five Star DP Epoxy Grout PG?
You can use it for depths from ½ inch to 6 inches. However, for applications requiring depths greater than 6 inches, contact Five Star Products for specific recommendations and technical support.
How long is the working time and when can equipment be put back in service?
The working time is 75 minutes at 70°F. Equipment can return to service once the grout achieves minimum required compressive strength and a compressive modulus of 1.0 x 10⁶ psi. Additionally, typical strength development shows 9,000 psi at 1 day and 13,000 psi at 7 days.
Can this grout be used in high temperature applications?
Yes, Five Star DP Epoxy Grout PG is designed for continuous service temperatures up to 180°F (82°C). Therefore, it suits hot process equipment and high-temperature industrial applications.
What surface preparation is required for optimal bond?
You should prepare concrete surfaces to achieve coarse aggregate exposure with a minimum ¼ inch peak-to-valley surface profile. Steel surfaces should be clean, dry, and free of oil, grease, and bond-inhibiting materials. Additionally, all surfaces must be free of contaminants.
How is the three-component system mixed and applied?
Begin by mixing Component B (hardener) with Component A (resin) for 1-2 minutes until uniform. Next, pour this mixture into a mortar mixer, add Component C (aggregate) one bag at a time, and mix only until the aggregate is completely wetted. Finally, you can pump or pour the grout into place using proper placement techniques.
What are the shelf life and storage requirements?
The product has a two-year shelf life in original unopened packaging when stored in dry conditions. However, high relative humidity will reduce shelf life. Therefore, proper storage in a controlled environment is essential.
