How Do Concrete Companies Use Flowable Fill?


Concrete companies utilize flowable fill, also known as controlled low-strength material (CLSM), as a versatile and efficient solution for various construction applications. This fill is a self-leveling mixture of cement, fine aggregate, water, and often fly ash or other supplementary cementitious materials. It has a relatively low strength compared to traditional concrete, making it ideal for specific uses.

One common application of this fill is as a backfill material for utility trenches. When excavating for underground utilities like water lines or sewer pipes, the fill is poured into the trench to fill voids and stabilize the area. Its self-leveling properties enable it to conform to the shape of the trench and provide even support for the utility lines.

This fill is also commonly used for filling abandoned or decommissioned underground tanks and voids. Its fluid nature allows it to flow into tight spaces and fill cavities, providing structural stability and preventing settling or shifting of the surrounding soil. Another essential application of this fill is for repairing and raising sunken concrete slabs, such as sidewalks, driveways, and highways. By injecting flowable fill beneath the sunken slabs, the concrete is lifted and leveled, eliminating tripping hazards and restoring the integrity of the pavement.

Its self-leveling properties, stability, and ease of placement make it an ideal choice for backfilling trenches, filling voids, and lifting sunken concrete slabs. It’s reliable for enhancing construction processes and ensuring long-lasting results. When you see for yourself just how useful it is, you’ll know you made the right choice.
