SikaFlow 678 – Deep-Pour Three-Component Epoxy Grout (1.8 CF Kit)
SikaFlow 678 is a high-performance, three-component epoxy grout engineered for deep-pour industrial applications where low heat generation and high structural performance are critical. This low-exotherm epoxy system allows for deep section pours—up to 18 inches in a single lift—without compromising strength or risking thermal cracking. With superior compressive strength up to 14,000 psi, long working time, and excellent bond to both steel and concrete, SikaFlow 678 is ideal for grouting baseplates, anchors, and heavy equipment foundations. The low-dusting formulation improves jobsite safety and workability while delivering long-term creep resistance even at elevated temperatures.
Key Features:
- Low-exotherm epoxy system enables deep pours up to 18 inches
- Excellent compressive strength – up to 14,000 psi at 28 days
- Long working time (up to 120 minutes at 70°F)
- Superior adhesion to steel and concrete substrates
- Outstanding creep resistance at elevated temperatures
- Low dust for safer jobsite handling
- Pumpable and pourable for versatile installations
- Pre-measured, easy-to-mix 1.8 CF kit
Applications:
- Grouting of compressors, drive motors, and turbines
- Baseplate and pump base grouting
- Anchor bolt, dowel, and bar grouting
- Repair of deteriorated curbs, bases, and columns
- Spalled concrete patching
- Heavy-duty equipment and machinery foundations
