Five Star Elastomeric Grout is a high-performance, three-component polyurethane system designed for flexible, vibration-resistant installations. It excels in environments where dynamic loads, thermal cycling, and chemical exposure occur regularly. Thanks to its unique formulation, it bonds tightly to both steel and concrete while effectively dampening sound and vibration.
This makes it well-suited for embedded rail systems, precision equipment bases, and structural repairs. In addition, its solvent-free composition reduces environmental impact and helps ensure safer handling. The fast-curing formula generates minimal exotherm, which allows for quicker turnaround and reduces downtime on critical jobs.
Whether you’re working in transportation infrastructure or heavy industrial foundations, Five Star Elastomeric Grout delivers the flexibility, durability, and performance that demanding applications require.

Frequently Asked Questions
What is the working time of Five Star Elastomeric Grout once mixed?
At 70°F (21°C), the working time is approximately 30 minutes, allowing for controlled placement.
What are the minimum and maximum placement thicknesses?
You can place the grout at a minimum thickness of 1 inch (25 mm) and a maximum of 6 inches (152 mm). For pours outside this range, it’s best to consult a sales representative for technical guidance.
How does it perform under dynamic or cyclic loading?
Five Star Elastomeric Grout offers proven fatigue resistance, showing less than 10% deflection after 16 million cycles at 5–250 psi. This performance makes it a strong choice for applications with high-frequency dynamic loads.
Is it suitable for electrical isolation?
Yes. With a volume resistivity greater than 1E12 Ohm-cm, it meets stringent requirements for electrical resistance in isolation-critical installations.
Can it be used in extreme temperature environments?
It can, but when temperatures fall outside the 60°F to 80°F (15.6°C to 26.7°C) range, contact a sales representative. They can provide recommendations to ensure proper placement and curing.
How should tools be cleaned after use?
Clean all tools with solvent or a strong detergent before the grout cures. Once hardened, removal becomes more difficult.
