Repair sea walls instead of replacing them by stopping high flow leaks, filling the voids behind concrete structures and binding loose soil with:
AP Fill 720 & AP Fill 700 — innovative, cost effective, water activated, low viscosity, simple to use closed cell polyurethane injection resins.
- Because these foams are impermeable to water once in place, the likelihood of future erosion is vastly diminished versus other commonly used fill materials.
- Originally developed over 30 years ago, and continuously improved since, this technology has one of the longest histories of success in the field among engineering uses of polyurethane foams.
- Phthalate free.
- Approved for contact with drinking water.
Quick Set Time vs Cement Grout
- AP Fill 700 & 720 foams set in 10 minutes or less.
- Cement grout takes hours to days.
Differences Between 700 and 720
- 720 has a higher expansion ratio and is more flexible when cured.
- 700 has a lower viscosity, so it works better in cooler temperatures.
