Five Star XP-230 Epoxy Grout is a high-performance, ultra-high strength grout formulated to meet the demands of critical industrial and structural installations. Engineered as the highest compressive strength epoxy grout in the Five Star product line, XP-230 is specifically designed for applications where reliable load support, fast project turnaround, and long-term durability are essential. Its three-component, 100% solids, solvent-free system delivers exceptional mechanical performance, with early strength gain rates that reduce downtime and support rapid installation schedules.

XP-230 offers outstanding fatigue resistance under dynamic loads, making it ideal for precision machinery, heavy equipment bases, and structural supports subject to vibration, torque, and cyclical stresses. The material’s low exothermic reaction enables deep pours up to 18 inches without excessive heat buildup, minimizing cracking risks and ensuring consistent, monolithic placements.

With high dimensional stability and a modulus of elasticity closely aligned with steel and concrete, XP-230 maintains bond integrity and structural performance over time. Whether used in wind towers, foundation rebuilds, or high-load industrial settings, Five Star XP-230 Epoxy Grout provides the strength, stability, and speed needed to maximize uptime and ensure long-term operational success.

Recommended Applications

Five Star XP-230 Epoxy Grout is formulated for precision grouting in demanding industrial and structural settings where performance under stress is critical. Its ultra-high compressive strength and excellent fatigue resistance provide long-term stability under heavy loads, dynamic vibration, and thermal cycling, making it a trusted solution for high-impact environments.

Typical applications include heavy machinery baseplate grouting, foundation rebuilds and retrofits, and wind tower bases where structural support and dimensional stability are essential. XP-230 is also ideal for crane rail and track grouting, high-load steel structure supports, and floor repair overlays that require exceptional compressive strength and durability.

Frequently Asked Questions

What makes XP-230 different from other epoxy grouts?

XP-230 offers the highest compressive strength in the Five Star portfolio, with superior early strength gain and exceptional fatigue resistance under dynamic loads.

What depth can XP-230 Epoxy Grout be placed in a single pour?

It can be placed up to 18 inches deep in a single lift without risk of thermal cracking. For pours greater than 18 inches, consult Five Star technical services.

Can XP-230 be used in cold weather?

Yes. XP-230 achieves fast strength gain even in colder temperatures, although working time and strength development rates may vary.

Is XP-230 suitable for high-temperature applications?

XP-230 is rated for continuous service up to 250°F (121°C), making it suitable for industrial environments exposed to elevated temperatures.

Does XP-230 shrink during curing?

No. It is a non-shrink epoxy grout as verified by ASTM C1090 testing, ensuring dimensional stability over time.

How should surfaces be prepared before applying XP-230?

Concrete surfaces should be clean, dry, and roughened to expose coarse aggregate. Metal surfaces should have an SSPC-SP6 commercial finish for optimal bond.
