American Rock Supply delivers bulk gravel, crushed stone, sand, soil, and mulch to homeowners and contractors in ZIP 91761 of Ontario, 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

We also carry Crushed Stone for drainage, masonry sand for paver joints, and boulders for accent features. Talk to our team about less common materials if your project requires a specialty product.

Material Selection by Project Type

  • Driveways: For a durable driveway in Ontario, start with a compactable base like crusher run. It locks together under weight and resists rutting. A top layer of clean stone or chip seal can finish the surface.
  • Drainage: Crushed Stone or drain rock works best around foundations, French drains, or retaining walls. Unlike crusher run, it has no fines so water flows through freely.
  • Patios and walkways: Use Stone Screenings or Natural Pea Gravel for a natural look. For paver patios, a crusher run base followed by a sand setting bed provides a stable, level surface.
  • Landscape beds and soil work: Decorative stone or mulch covers garden beds while top soil or garden soil rebuilds planting areas. Choose mulch for moisture retention or stone for low maintenance.

Local Conditions That Affect Material Choice

ZIP 91761 in Ontario mixes older built-up residential lots with newer subdivisions and some semi-rural acreage. The terrain is mostly flat with small slopes near drainage channels.

Soils in this area often contain clay, which can hold water and shift under heavy loads. That makes a compacted base layer important for driveways and patios. During dry summers, Stone Screenings and crusher run hold up well without excessive dust.

Rainfall is seasonal. When wet, clay soils become soft. Scheduling delivery on dry ground helps avoid ruts and ensures proper compaction. For drainage projects, clean stone moves water away from structures more effectively than materials with fines.

Delivery and Access in ZIP 91761 of Ontario

American Rock Supply is delivery-only. We bring bulk materials directly to your property in ZIP 91761.

Most single-family lots in the ZIP have adequate driveway access for our trucks. Longer rural driveways may require a clear path and a turnaround area at the drop point. Tight suburban lots need room for the truck to maneuver without blocking traffic or damaging curbs.

Overhead branches, low wires, or soft ground after rain can limit where we can dump. Let us know about your access conditions when you schedule. We serve much of ZIP 91761 and will work with you to find a safe, convenient drop location.

What aggregate is best for a residential driveway in Ontario?

Crusher run is the most common choice for driveways. It contains angular stone and fines that compact into a firm surface. For a finished look, top with a layer of clean gravel or chip seal.

What is the difference between crusher run and Crushed Stone?

Crusher run includes small dust and fines that help it lock together when compacted. Crushed Stone has been washed to remove fines, leaving only uniform sized gravel. Use crusher run for driveways and base work; use clean stone for drainage applications where water needs to flow through.

What material works best for drainage around a foundation?

Crushed Stone (1 inch to 1.5 inch) is ideal for foundation drainage. It creates void space that allows water to move away from the structure without clogging. Avoid materials with fines, as they can compact and block drainage over time.

How do I figure out how much material I need?

Measure the length and width of the area in feet, then multiply by the desired depth in inches. Divide by 12 to convert depth to feet, then multiply length by width by depth to get cubic feet. Divide by 27 to get cubic yards. For help estimating, contact us with your project dimensions and use case.
