American Rock Supply delivers bulk gravel, crushed stone, sand, soil, and mulch to homeowners and contractors in ZIP 91758 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

Secondary materials like sand, mulch, and riprap are also available for specific grading, erosion control, or planting needs. The team can help match the right product to the site conditions.

Material Selection by Project Type

  • Driveways: Crushed stone with fines compacts into a solid base that resists rutting. A 4 to 6 inch base layer works well for most residential driveways in the area.
  • Drainage: Crushed Stone or drain rock without fines allows water to flow freely. This prevents pooling around foundations and low areas.
  • Patios and walkways: Stone Screenings or crushed stone base provides a stable foundation. A top layer of Natural Pea Gravel or Stone Screenings gives a clean, finished surface.
  • Landscape beds and soil work: Decorative stone like Natural Pea Gravel or river rock adds visual appeal. Topsoil or garden soil supports plant growth and improves existing dirt.

Local Conditions That Affect Material Choice

ZIP 91758 covers a mix of older established lots and newer subdivisions in Ontario. The terrain is mostly flat to gently sloping, with some areas having clay-rich soil that drains slowly.

In the older sections, lots are tighter and driveways may be shorter. Newer subdivisions often have larger lots with more landscaping space. The dry climate means that materials with fines hold moisture better, but clean stone is needed where drainage is a priority.

After heavy rain, clay soil can become soft. Compactable base materials work best in these conditions to avoid shifting. Most properties have good access, but overhead branches or narrow gates may affect drop location choices.

Delivery and Access in ZIP 91758 of Ontario

American Rock Supply is delivery-only. We bring bulk materials directly to your property in ZIP 91758.

Trucks can access most driveways in the area. Long rural driveways may require a turnaround spot or a clear path to the drop zone. Tight suburban lots should have room for the truck to back in or pull through.

Soft ground after rain can make it hard for trucks to unload. Pick a dry, level spot for the material. Overhead wires or low branches may limit where a dump truck can position. Let the team know about any access concerns when you order.

Single loads for homeowners and larger contractor orders are handled the same way. We serve much of ZIP 91758 and can work with your site conditions.

Frequently Asked Questions

Common questions about delivery to 91758 in Ontario, CA

Does American Rock Supply deliver to ZIP 91758?

Yes, we deliver bulk aggregates to properties in ZIP 91758 of Ontario, CA. We serve both homeowners and contractors in the area.

What aggregate is best for a residential driveway in Ontario?

Crushed stone with fines, often called crusher run, is a top choice. It compacts into a firm, durable surface that handles vehicle traffic well.

What is the difference between crusher run and Crushed Stone?

Crusher run contains fines that bind the stone together when compacted. Crushed Stone has no fines, so it stays loose and drains water easily.

What material works best for drainage around a foundation?

Clean drain rock or Crushed Stone is recommended. It allows water to pass through without clogging or settling.

Can material be delivered to long driveways or tight lots in ZIP 91758?

Yes, as long as the truck can reach the drop area. Let us know about driveway length, narrow entrances, or overhead obstacles when you order.
