Fill Flow


SKU: 95669 Category:

As more and more utility lines are moved underground, the demand for controlled low-strength materials increases at an equal rate. This type of concrete mixture, also known as flowable fill, allows easy access to cable, pipes, and powerlines buried beneath roads. It is strong enough for cars and trucks to drive on it, but weak enough to excavate for repairs on the utilities below. Creating a mix that meets these specifications can be a challenge, which is why Fritz-Pak developed our flowable fill admixture, Fill Flow. This powerful admixture not only makes it easier to create controlled low-strength material but also vastly improves the quality of the finished product.

How Does Our Flowable Fill Admixture Work?

Traditional low-strength mixes are made with a higher water-cement ratio. This produces the desired strength, but it can also result in excess bleed water. This extra water often has to be pumped out of the trench after the mix settles. Fritz-Pak’s Fill Flow uses entrained air to increase the volume of the concrete while also lowering the compressive strength. Using this chemistry instead of water lowers the risk of excess bleed water and saves money on additional materials.

Benefits of Fill Flow Flowable Fill Admixture

  • Produces flowing concrete
  • Minimal shrinkage or segregation within the mix
  • Place mix directly from the truck
  • No more compaction backfill
  • Produces stable air content
  • No excessive bleed water
