A Flowable Fill Admixture for Better CLSM with Less Bleed Water

Looking for an alternative way to produce controlled low-strength materials for backfilling trenches? Traditional mixes require a lot of excess water. Not only does this increase the cost of load, but it can also result in bleed water that has to be pumped out of the trench the next day. What if there was a cost-effective way to increase the load volume and lower the risk of bleed water? Fritz-Pak’s flowable fill admixture, Fill Flow, offers all these benefits and more.

What Makes this Flowable Fill Admixture Unique?

Fill Flow is a powerful surfactant that dramatically increases the entrained air in the concrete. This improves the concrete’s flow and lowers the load’s overall compressive strength with extra water. The added air also increases the truck’s volume, which means that you can fill the same size trench with less material. And don’t forget about the other benefits this  admixture offers.

  • Produces flowing concrete
  • Minimal shrinkage or segregation within the mix
  • Place mix directly from the truck
