Flowable Fill
Flowable Fill from On-Demand Concrete meets all flow fill requirements
Flowable fill is a self-leveling, self-compacting controlled low-strength material suitable for commercial or residential projects. Because it has a high slump (very wet), it’s ideal for filling voids around plumbing, electrical, or drainage lines without the need for tamping or special equipment. Its high fluidity means it flows easily into tight or irregular spaces, making it perfect for backyard repairs, trench backfills, or small-scale slab support—especially when access is limited or traditional compacting isn’t practical.This saves you time and money in compacting equipment, labor, and testing.
On-Demand Concrete offers traditional CDOT Flow Fill as well as a its proprietary product Quick Set Flow Fill. This has been approved by CDOT, City and County of Denver, Aurora and most cities along the Front Range under the Flashfill category and achieves strength in less than 30 minutes. Quick Set Flow Fill allows you to patch with asphalt or concrete within an hour, getting your driveway, patio, or sidewalk back in use fast, without drawn-out drying times or multiple contractor visits.
Common residential applications of flowable fill include:
- Backfilling utility trenches (water, sewer, electrical)
- Supporting sidewalks, patios, and driveways
- Filling voids under steps or concrete slabs
- Small foundation or retaining wall projects
- Leveling landscaping in yards
- Safely decommissioning old septic tanks or utility lines
- Reinforcing soil and preventing washouts
Save Time and Money
Under estimate what you needed? Our trucks carry the raw materials and can likely mix more to finish the job. Over ordered? No worries – we’ll use the extra for another job. You pay only for what you use, every time.
With On-Demand Concrete, there’s none of the mess and hard work of trying to mix and pour concrete yourself. Our systems create no waste, so the only clean out we need is about a wheelbarrow’s worth to clean off the mixing auger. The truck will simply drive up to your location, pour the concrete, and leave. It couldn’t be easier. And we do weekend deliveries, too!
