American Rock Supply delivers bulk gravel, crushed stone, sand, soil, and mulch to homeowners and contractors in ZIP 94528 of Diablo, California (CA).

Common projects include residential driveways, paver patios, drainage work, landscape beds, lawn repair, and base preparation for sheds, outbuildings, and small contractor jobs.

Products and Materials

Secondary materials such as masonry sand, fill dirt, and garden mulch are also available for finishing work, utility filling, and weed suppression.

Material Selection by Project Type

  • Driveways: Crushed stone with fines (crusher run) compacts into a solid base. A deep base layer prevents rutting under heavy vehicles.
  • Drainage: Crushed Stone or drain rock, without fines, allows water to move quickly through French drains or around foundations.
  • Patios and walkways: A compacted base of paver base (Road Base) provides a level surface. Top with setting sand and pavers for a durable finish.
  • Landscape beds and soil work: Use decorative gravel or mulch for weed suppression and aesthetics. For planting, choose screened topsoil or amended garden soil.

Local Conditions That Affect Material Choice

ZIP 94528 in Diablo includes a mix of larger rural properties and wooded residential lots. Many homes sit on sloped terrain with clay-rich soils that drain slowly.

Winter rain can saturate the ground, so drainage projects are common. Driveways on steep slopes benefit from angular crushed stone that locks together.

The area experiences mild temperatures but occasional freeze-thaw cycles in winter. Using compactable base materials reduces frost heave on driveways and patios.

Frequently Asked Questions

Common questions about delivery to 94528 in Diablo, CA

Does American Rock Supply deliver to ZIP 94528?

Yes, we deliver bulk aggregates to Diablo and surrounding areas within ZIP 94528. Contact us with your full address to confirm access and schedule a drop.

What aggregate is best for a residential driveway in Diablo?

Crushed stone with fines, often called crusher run or Class II base, compacts well and provides a stable surface for vehicles. A base depth of 4 to 6 inches is typical for residential driveways.

What material works best for drainage around a foundation?

Clean drain rock or washed crushed stone without fines is best. These materials allow water to move away from the foundation quickly, reducing hydrostatic pressure.

Can material be delivered to long driveways or tight lots in ZIP 94528?

Yes, our trucks can navigate most long driveways and tight spaces. We recommend measuring the width and height of your driveway. Overhead obstacles like branches may limit access.

How do I figure out how much material I need?

Estimate the volume in cubic feet or yards based on your project area and depth. For exact quantities, contact us with rough dimensions and a description of the project.
