Foundation Backfill in Superior
Foundation backfill in Superior requires structural fill at $25/yard delivered. Superior sits on the Boulder Creek alluvial / foothills shale — a mix of sandy creek-alluvial soil and, near the foothills, expansive shale-derived soil with a well-documented local heave history. Foundation work here must also account for Colorado's freeze-thaw cycles — backfill that holds water can frost-heave against the foundation, causing cracking and movement. We deliver structural fill that meets 95%+ Standard Proctor compaction specs when installed in 6-8 inch lifts. For critical applications, we can provide quarry-sourced material with gradation documentation for engineering inspection.

Foundation Backfill FAQ — Superior
Always use structural fill ($25/yd) for foundation work — never regular fill dirt or topsoil. Structural fill is engineered to compact properly and resist settling under load.
Pier backfill: 1-3 yards per pier location. Plumbing tunnel backfill: 2-5 yards per tunnel. Full foundation pad: 50-200 yards depending on house size. Text us your project details for an exact estimate.
For new construction and major repairs, yes — most Superior building inspectors require compaction testing documentation. We can provide material with gradation reports for engineered projects.
No. Regular fill dirt ($15/yd) is fine for yard leveling and pool removal but lacks the engineered compaction characteristics needed for load-bearing applications. Foundation work requires structural fill ($25/yd).
Our clean fill dirt comes from a network of local excavation, grading, and construction projects near each delivery site — not a quarry or aggregate yard. That cuts out aggregate-yard markup and keeps haul distance short, which is what lets us offer the lowest delivered price on fill dirt rather than pricing off a fixed rate card. Every load is still screened for debris before delivery — sourcing locally doesn’t mean lower quality, it means lower cost.
