Adhesives Technology Accu-Grout HD is a high-performance, three-component epoxy grouting system designed to handle the extreme mechanical and environmental demands of industrial equipment installations. Engineered for use in settings where static and dynamic loads are significant, this formulation offers exceptional compressive strength — reaching up to 21,000 psi at elevated temperatures — and resists deformation under long-term stress. Its robust composition ensures dimensional stability even in applications subjected to constant vibration, impact, and thermal cycling.
This grout is particularly suited for structural baseplate grouting in sectors such as wind energy (both onshore and offshore), petrochemical processing, marine infrastructure, pulp and paper, and heavy manufacturing. The system provides precise flow characteristics for full bearing contact, while its negligible shrinkage and high bond strength contribute to reliable, long-term equipment alignment. Additionally, it also offers strong resistance to oils, solvents, and aggressive chemicals, making it a trusted choice for installations in corrosive or temperature-variable environments.
Whether setting new machinery or re-grouting critical supports, Accu-Grout HD ensures lasting integrity under extreme service conditions.

Frequently Asked Questions
What makes Accu-Grout HD different from other grouts?
Accu-Grout HD is formulated for high-load, high-vibration environments. It reaches compressive strengths up to 21,000 psi at 105°F. In addition, it holds up under chemical exposure and thermal cycling, making it suitable for demanding industrial conditions.
What is the maximum pour depth?
You can pour up to 6 inches in a single lift. For deeper placements, use multiple lifts to maintain proper cure and performance.
How long does it take Accu-Grout HD to cure?
Cure time depends on temperature. At 75°F (24°C), the grout typically reaches full strength in 36 to 42 hours. Initial cure occurs within 24 to 48 hours under most conditions.
Can it be used in marine or offshore installations?
Yes. Accu-Grout HD performs well in marine environments and sees frequent use in offshore wind turbine baseplate applications.
What is the working time after mixing?
Working time varies with ambient temperature. In general, you’ll have 15 to 45 minutes. Warmer conditions shorten the window.
What is required for surface preparation?
Before placement, clean and dry all concrete surfaces and remove any contaminants. Expose sound aggregate. For steel, blast to a white metal finish to ensure proper bond.
