Grouting Problems
| Problem | Solution |
| Slow reaction | Tubes are cold. Immerse in hot water for 5 minutes. |
| Grout Washes Out | Water looks 'milky'.
Stop pumping to allow grout to react in the first 3 to 5 inches of
mixer, and then resume pumping. Repeat as required. Make sure output (water) is plugged with burlap, rags, or oakum. Force any of the above into cracks with a screwdriver and hammer. Move injection hole further away from output. |
| Very fast moving water creating a wash-out | Slide a party balloon(punch balloon) over static mixer. Tape end of balloon onto mixer. Insert mixer into pre-drilled hole and inject. Reacted material will expand and balloon will pop. This will put reacted material into your fast moving water. |
| Quick Reaction | Tubes are too warm. Cool by placing tubes in 70° F. water. |
| Leaking Around Mixer Tube in Hole | Wrap a rag or burlap around the static mixer, tape to the mixer and then tap the mixer into the hole. |
| Difficult to Disengage Trigger Release | Tap trigger release with a small hammer then slide plunger back. |
Clean Up
• Snap mixers (15 minutes after injection) with a
_ sharp downward motion.
• Use a putty knife to scrape excess material from concrete.
• Dispose of waste foam with ordinary wood or plastic waste.
