Flow Fill or CDF

Contact JOB MIX CONCRETE for your next flow fill job. Flow Fill is also known as CDF, Controlled Density Fill, Controlled Low-Strength Material, Flowable Mortar, Plastic Soil Cement and K-Krete.  The benefits of using Flow Fill or CDF

  • Flow fill or CDF does not form voids during placement, and won’t settle or rut under loading. This advantage is especially significant if the back fill in a utility trench is to be covered by a pavement patch. Soil or granular fill, if not compacted properly, may settle after a pavement patch is placed and forms cracks or dips in the road.

  • Controlled Density Fill mix designs can be adjusted to meet specific requirements and a variety of performance characteristics.

  • Workers can place Controlled Low-Strength Material in a trench without entering the trench, reducing their exposure to possible cave-ins.

  • Depending on the type and location of void to be filled, flow fill can be placed by chute, conveyor, pump, or bucket. Because flowable fill is self-leveling, it needs little or no spreading or compacting. This speeds construction and reduces labor requirements.

  • Flowable fill allows narrower trenches because it eliminates having to widen trenches to accommodate compaction equipment and laborers in the trench.

  • Unlike soil or granular backfill,Controlled Density Fill, can be placed without rollers, loaders, or tampers.
