American Rock Supply delivers bulk gravel, crushed stone, sand, soil, and mulch to homeowners and contractors in ZIP 94028 of Portola Valley, 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 Stone Screenings, mulch, and concrete sand are also available for specific projects. These options complement the primary choices above.

Material Selection by Project Type

  • Driveways: Use a compactable base material such as 3/4 inch crushed gravel. Proper compaction prevents rutting and extends the driveway life.
  • Drainage: Crushed Stone or drain rock moves water away from foundations and low spots. Avoid materials with fines that can clog the system.
  • Patios and walkways: Start with a firm crushed base, then top with sand or fine stone dust for leveling pavers. This combination resists settling.
  • Landscape beds and soil work: Choose decorative river rock or bark mulch for beds. Use screened topsoil or garden soil for planting areas to improve fertility.

Local Conditions That Affect Material Choice

Portola Valley in ZIP 94028 features a mix of large rural lots and hillside properties. Many homes sit on sloped terrain with native clay soils that drain slowly.

During the rainy season, runoff can be significant. Using clean stone around structures and in drainage paths helps manage water. Driveways on steep grades may need extra base thickness to stay stable.

The area experiences mild winters with occasional frost. Freeze-thaw cycles can shift poorly compacted driveways. Choosing angular, interlocking aggregates reduces movement over time.

Delivery and Access in ZIP 94028 of Portola Valley

American Rock Supply delivers to much of ZIP 94028. Our trucks can handle long rural driveways and tight suburban access points.

Before scheduling, check for overhead branches, low wires, or narrow gates. Steep grades and soft ground after rain may require a designated drop spot. Single-load homeowner orders and larger contractor deliveries are both welcome.

Plan for adequate turnaround space so the truck can maneuver safely. We will work with you to find the best access point on your property.
