For a 50' × 30' building pad raised 12", plan on about 56 cubic yards of borrow. For a typical residential driveway grade-raise (40' × 12' × 6" deep), you're looking at 9 cubic yards. For retaining wall backfill on a 40' wall × 8' tall × 24" deep, roughly 24 cubic yards. Rule of thumb: 1 cubic yard covers about 100 square feet at 3" depth. Order 15–20% extra for compaction losses on structural fill. How Common Borrow compares vs. Fill Dirt — Same material family. Fill Dirt is the residential listing for grading and landscape projects where Mass DOT spec isn't required. Common Borrow is the spec-compliant grade for public-works, commercial structural fill, and any job where the engineer or DPW requires M1.01.0 compliance. vs. Site Loam (Mass DOT M1.04.0) — Borrow is structural — the bulk material that raises grade and supports loads. Loam goes on top — the topsoil for finish grade, lawn establishment, and landscaping. You typically order both for a complete site-prep job. vs. Dense Pack ¾" to minus — Dense pack is processed gravel for pavement sub-base. Common Borrow is unprocessed structural fill for the volume underneath, then dense pack on top as the engineered sub-base. vs. RCA — Recycled Concrete Aggregate — RCA is recycled concrete aggregate used as sustainable base/sub-base. Common Borrow is virgin earth used as structural fill. Different applications. Frequently asked questions What's the difference between Common Borrow and Fill Dirt? Same material family. Common Borrow is the spec-compliant Mass DOT M1.01.0 grade contractors order by name on public-works and engineered projects. Fill Dirt is the residential listing for the same material when spec compliance isn't required. Is Common Borrow Mass DOT compliant? Yes. Our Common Borrow meets Mass DOT M1.01.0 specification for structural fill, including stone size, organic content, and gradation. We can provide tickets and material certifications on request for spec-compliant projects. What's the maximum stone size? 6 inches per Mass DOT M1.01.0 spec. Larger fragments are screened out at our yard. Can I use Common Borrow for backfilling a foundation? Yes — Common Borrow is appropriate for structural backfill around foundations, behind retaining walls, and under slabs when compacted in lifts to engineer-specified density (typically 95% standard Proctor). How much for a typical grade-raise project? Depends on area and depth. A 50' × 30' building pad raised 12" needs about 56 yards. Use the rule of 1 yard per 100 sq ft at 3" depth and multiply for thickness. Do you deliver in the Boston area?
