SikaFlow 647 – Liquid Epoxy Grout (2.5 Gallon Kit)
SikaFlow 647 is a two-component, modified epoxy resin-based liquid grout formulated for precision structural grouting applications. Designed for both pressure and gravity feed installation methods, this grout offers exceptional penetration into voids, cracks, and fissures, even in damp or lightly oil-contaminated substrates. It is ideal for repairing cracked concrete, bonding post-tensioned elements, and grouting vibrating or rotating equipment bases. With its low viscosity, strong chemical resistance, and the ability to cure in various environmental conditions, SikaFlow 647 is suitable for demanding industrial applications and can be extended with aggregate for use as epoxy mortar in deep fill and patching jobs.
