Chip Rock vs. River Rock: What’s the Difference and Which One Should You Use?

When it comes to landscaping and construction materials, gravel isn’t just gravel — choosing the right type of rock can make or break your project. Two of the most popular options in Western Montana are chip rock and river rock, each with unique strengths and ideal uses.

If you’re not sure which one to use for your driveway, pathway, drainage system, or garden bed, this guide breaks down the key differences between chip rock and river rock, including local delivery options in the Missoula area.

🪨 What Is Chip Rock?

Chip rock, also called crushed gravel or fractured rock, is produced by mechanically crushing larger stones or gravel. It has:

  • Angular edges

  • A rough texture

  • Great compaction ability

Best Uses for Chip Rock:

  • Driveways and road base

  • Pathways and walkways

  • Under concrete slabs

  • Backfill for retaining walls

  • Drainage layers

Because chip rock packs tightly, it forms a firm, stable surface — ideal for areas that see foot or vehicle traffic.

✅ We carry chip rock in various sizes (¾”, 1.5”, etc.) and deliver throughout Missoula.

🏞 What Is River Rock?

River rock is a naturally tumbled stone harvested from riverbeds and streambeds. It features:

  • Rounded edges

  • Smooth surface

  • Varied textures

Best Uses for River Rock:

  • Decorative landscaping

  • Dry creek beds and drainage swales

  • Around garden beds and trees

  • Erosion control

  • Accent borders and water features

River rock doesn’t compact well but offers visual appeal and excellent drainage, making it perfect for design-focused projects.

🎨 We stock river rock in multiple sizes and tones — available for bulk delivery in Missoula, Frenchtown, and Lolo.
