FlowFill™: Flowable Fill That Simplifies Backfill

FlowFill™ is a flowable fill solution designed to eliminate compaction, reduce labor, and fill voids quickly and reliably. Perfect for trench backfill, abandoned structures, utility encasement, and hard-to-reach areas, FlowFill™ provides a strong, non-shrinking alternative to traditional compacted soil.

No Compaction, Easy Placement

FlowFill™ flows easily into place without the need for tamping, lifts, or compaction equipment. It reaches confined spaces effortlessly, reduces in-place costs, and virtually eliminates settlement-related callbacks, ensuring long-term stability for pavements and structures above.

About

United Materials offers versatile delivery options to match your project needs. Choose the right truck for efficient aggregate placement.

Perfect for precise, long-distance placement on large projects, bridge abutments, and tight access zones requiring accuracy and minimal site disruption.

Fast and Labor-Saving

Pour directly from the truck continuously or in lifts—no compaction tools or extra crew required.
