SikaFlow-647
SikaFlow-647 is a two-component modified epoxy-resin grout for pressure injection or gravity feed into voids, cracks, and baseplates. It bonds to properly prepared concrete or steel that is wet, dry, or oil-contaminated, including cracks that still hold water. Typical work includes compressors, generators, pumps, and other vibrating machinery, plus thin-bed repairs and precast pile bonding.
Key Features
- Two-component modified epoxy-resin liquid grout
- Pressure injection or gravity feed fills fine cracks and voids
- Bonds to damp or oil-contaminated concrete and steel
- Meets ASTM C881 Type I, II, and IV, Grade 1 and 2
- Solvent-free and VOC compliant
- Working time approximately 20 to 30 minutes at 75 F
Applications
- Baseplates under compressors, generators, and pumps
- Vibrating and rotating machinery pads
- Crack repair in concrete, including wet cracks

Frequently Asked Questions
What machinery bases is SikaFlow-647 used under?
Baseplates under compressors, generators, pumps, cement mills, and other vibrating or rotating machinery. It is also used for thin-bed repairs, cracked concrete, precast pile bonding, and post-tensioned beam work.
What substrates does SikaFlow-647 bond to?
Properly prepared concrete or steel that is wet, dry, or oil-contaminated. It can repair cracks that still contain water. It is not formulated for underwater repair.
What ASTM C881 types does SikaFlow-647 meet?
ASTM C881 Type I, II, and IV, Grade 1 and 2. That listing covers structural bonding and load-bearing epoxy grout uses on the published sheet.
What working time does SikaFlow-647 have at 75 F?
Approximately 20 to 30 minutes at 75 F when the components are conditioned correctly. At 90 F working time shortens to approximately 10 to 20 minutes; at 55 F it extends to approximately 30 to 40 minutes.
What neat thickness limit does SikaFlow-647 have?
Neat binder is limited to a maximum of 1/4 in. Greater thickness uses the epoxy mortar option with oven-dried aggregate per the PDS.
What yield does the 2.5 gal SikaFlow-647 kit deliver?
Approximately 0.33 ft3 (575 in3) of neat mixed product. A full kit mixed with 120 lb of Sikalastic-941 aggregate yields approximately 1.15 ft3 of epoxy mortar.
