Many cement-based mixtures used for construction projects look like concrete and have a similar consistency. However, they are made at different grades and strengths and serve various purposes. One such widely used mixture is flowable fill. Miller's Ready Mix Concrete & Block, the premier concrete supplier, in Mayfield, NY, sheds some light on what the substance is and the role it plays in construction.

What Is Flowable Fill?

Flowable fill is a controlled low-strength material made from a mixture of cement,  sand, and water. Like concrete, it is applied in a semi-liquid or flowable form and hardens within a few hours. Since the mixture uses a fine aggregate and has minimal air bubbles, it is self-leveling and doesn’t need tamping and vibration.

Why Is It Used in Construction?

Also known as controlled low strength material (CLSM) or controlled density fill (CDF), flowable fill is a compound that can be used as backfill material for poorly compacted soil. A concrete supplier may use it for pavement bases, conduit bedding, or to occupy the subbase of a building foundation. The option is also frequently used to fill hard to reach places such as underground tanks, abandoned wells, and around industrial piping. It also has a higher fill capacity than alternative materials and doesn’t need manually compacting, reducing the size and number of people entering the excavated area. As such, it can save construction companies time and labor costs and make the work site safer.

Concrete suppliers will deliver flowable fill to the site in a truck equipped with a transit mixer. The transit mixer is a rotating drum that churns the material to prevent it from hardening while on the road. Once the truck reaches its destination, the mix is poured down a chute and into the area that needs filling. They can also pump it or manually transport it in a wheelbarrow.
