Fill Dirt in Calexico, CA

Generally yes. In Calexico, basic fill dirt (unprocessed subsoil) usually costs less per cubic yard or ton than crushed gravel because it requires less processing and screening. Keep in mind cost varies by supplier, truck access, and delivery distance, so request a quote for an exact price.

Fill dirt is mostly native subsoil and fines used to raise grade or backfill; it does not drain well or create a finished surface. Gravel is crushed rock used for drainage and stable surfaces. For Calexico projects, choose clean, low-organic fill dirt for structural backfill and gravel for driveways or patios.

You should not use fill dirt as a finished driveway surface. Fill dirt can be used under a compacted base to build up grade, but top it with compacted base rock or crushed gravel for durability. If covering grass, remove or kill vegetation first and compact the fill in layers to reduce future settling.

Volume = area x depth, so 1,000 sq ft x 0.5 ft = 500 cubic feet, which is about 18.5 cubic yards. Depending on soil density, that equals roughly 22 to 28 tons of fill dirt. Order an extra 5-10% to allow for settlement and compaction.

Truck loads vary by truck type and local supplier. Hello Gravel partners commonly dispatch dump trucks ranging from small loads (3 tons) up to tri-axle trucks that can carry roughly 10 to 15 cubic yards, depending on local configuration. Contact us to confirm available truck sizes and the exact load for your zip code.

Assuming a common driveway width of 10 ft and a 4-inch build-up: area = 20 ft x 10 ft = 200 sq ft; depth 4 inches = 0.333 ft, so volume = about 66.7 cubic feet or 2.5 cubic yards. Fill dirt can be used to raise the grade but should be compacted and finished with 3-4 inches of crushed base rock for the driving surface.

No. Two inches of fill dirt is insufficient for a driveway base because it will settle and won’t provide structural support. For projects in Calexico, plan on at least 4 to 6 inches of compacted fill or engineered base, then add a 3-4 inch layer of compacted crushed rock on top for a durable surface.

No, fill dirt is not a good material for drainage because it contains fines that hold water. For drainage solutions in Calexico’s arid environment, use clean drain rock or gravel and perforated piping for French drains or dry wells. If you must backfill, place drainage rock around the pipe and cap with soil.

A 50 lb bag of dirt contains roughly 0.6 cubic feet of material, which is about 0.02 cubic yards. That covers only a very small patch or hole. For yards or driveway-grade work, bulk delivery is more economical and practical.

No. Fill dirt does not harden like concrete; it remains soil and will compact over time. If you need a hard, paved surface, use concrete, asphalt, or a stabilized base material; soil stabilization with lime or cement requires a contractor and engineering for reliable results.

Use clean, low-organic fill dirt and place it in 4 to 6 inch lifts, compacting each layer with proper equipment. Control moisture during placement and allow time for settlement; order 5-10% extra material to account for shrinkage. For critical or structural areas, consider geotextile fabric and a compaction test from a local engineer.
