Five Star HP Epoxy Grout – High Flow is a precision-grade, 100% solids epoxy system built for industrial settings that demand high strength, excellent flow, and consistent performance in tight clearances. This three-component mix — resin, hardener, and pre-packaged aggregate — creates a high-flow grout that moves easily through narrow baseplate gaps while supporting the loads of heavy equipment.
Because it’s engineered for ease of placement, this formulation flows smoothly and expands slightly to fill voids and maintain uniform contact beneath baseplates. It also cures rapidly, reaching 10,000 psi in just 16 hours, which helps speed up equipment turnaround and reduce downtime. Unlike traditional grouts, it resists long-term creep and deformation even at elevated temperatures, helping maintain precise alignment and load transfer.
Additionally, the grout bonds strongly to properly prepared concrete and steel. It’s solvent-free and highly chemical-resistant, making it ideal for use in harsh environments. Whether supporting compressors, turbines, pumps, or structural machinery, this high-flow epoxy performs reliably in power plants, chemical facilities, and other demanding industrial applications where flowability and strength are both critical.

Key Features of Five Star HP Epoxy Grout
- High-Flow Formulation for Tight Clearances
Designed for efficient placement in baseplates with as little as 1 inch of clearance — ideal when flowability is critical but access is limited. - Rapid Strength Gain
Reaches compressive strengths of 10,000 psi in 16 hours and 14,000 psi within one day. - Non-Shrink with Positive Expansion
Expands slightly during cure per ASTM C827, helping maintain alignment and bearing support. - Exceptional Creep Resistance
Resists deformation under sustained loads and high temperatures. - Excellent Bond to Concrete and Steel
Develops structural-grade adhesion for critical baseplate and equipment support. - Chemically Resistant and Solvent-Free
Handles exposure to industrial chemicals without shrinkage or degradation.
Recommended Uses for Five Star HP Epoxy Grout

- Baseplates with clearances of 1 inch or more
- Wind turbine and generator foundations
- Pumps, compressors, and other rotating equipment
- Chemical processing units and wastewater systems
- Anchor bolt and dowel placements
- Jobs requiring fast strength gain and limited shutdown time
Best Used When:
- Equipment clearance ranges from 1 to 4 inches
- Full coverage under tight baseplates is critical
- Downtime must be kept to a minimum
- Operating temperatures may reach elevated levels
- Reliable load transfer and long-term stability are required
Frequently Asked Questions
What’s the minimum clearance required for Five Star HP High Flow Epoxy Grout?
This grout needs only 1 inch of clearance beneath the baseplate, which makes it well-suited for confined or tight-access installations.
How soon can I put equipment back in service?
You can typically restart equipment after 16 hours at 70°F, once the grout reaches sufficient compressive strength.
Can I pour this version of Five Star HP High Flow Epoxy Grout?
Yes. Thanks to its high-flow formulation, you can easily place it by pouring through a headbox or similar setup.
Does HP High Flow resist both chemicals and heat?
Absolutely. It withstands harsh chemical environments and performs reliably in continuous temperatures up to 180°F (82°C).
What surface preparation is needed before installation?
Concrete and steel must be clean, dry, and properly profiled to ensure bond performance. Always follow the manufacturer’s surface prep guidelines.
Can HP High Flow be used for thicker pours?
Generally, it’s intended for depths between 1 and 4 inches. If your application exceeds this range, consult a sales representative for best practices and alternate options.
