Foundation Backfill in San Antonio
Foundation backfill in San Antonio requires structural fill at $20/yard delivered. San Antonio sits on the Blackland Prairie / Balcones Escarpment: dense, expansive Blackland clay across the east and south, and thin, rocky soil over limestone in the Hill Country to the north. Expansive clay like that puts heavy pressure on foundations as it swells and shrinks, so backfill after pier installation, plumbing repair, or any foundation work needs to match or exceed the original soil's structural performance. 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: San Antonio
Always use structural fill ($20/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 San Antonio building inspectors require compaction testing documentation. We can provide material with gradation reports for engineered projects.
No. Regular fill dirt ($10/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 ($20/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.
