SikaFlow 649 – High-Strength, High-Flow Epoxy Grout (1.7 CF Unit)
SikaFlow 649 is a precision, three-component epoxy grout engineered for the demanding needs of heavy equipment support and high-torque applications. It features high early and ultimate compressive strengths, excellent flow characteristics, and superior load-bearing capacity—making it ideal for use in grouting compressors, generators, turbines, pumps, and rotating machinery. SikaFlow 649 withstands elevated service temperatures and dynamic loads, making it suitable for crane rails, crusher ball mills, and wind turbine bases. Its ability to deliver consistent placement even in thin pours and extended distances ensures superior performance in critical baseplate applications.
Key Features:
- High compressive strength up to 20,000 psi in 96 hours
- High flow for long-distance and thin-pour applications
- Meets API 610 and API RP 686 standards for rotating equipment
- Withstands high service temperatures up to 155°F (68°C)
- Excellent bond to concrete and steel surfaces
- Resists impact, torque, vibration, and chemical exposure
- Can be pumped or poured for flexible installation
- Suitable for critical baseplate and anchor bolt grouting
Applications:
- Precision alignment of compressors, turbines, and generators
- Baseplate grouting for pumps, motors, and heavy machinery
- Grouting wind turbine tower bases
- Post-tensioning pour-back grouting
- Crusher mills, slab tables, crane rails, and anchor bolt grouting
