What is cobble?

Natural Rock. Big Impact.

Cobble is large, naturally rounded river rock ranging from about 2" to 8". Keep in mind it isn't a shiny decorative stone. It can look gray and dull, and some of the larger pieces may be broken with rougher edges.

It's a favorite for dry creek beds, borders, banks and drainage swales where you want rock that looks great and handles water. Because the stones are large, plan on placing them by hand or with equipment.

Cobble questions

Good Questions. Straight Answers.

What size is 2"–8" cobble?

Most stones range from about 2" up to 8" across, with a mix of sizes in between. It's natural river rock, so shapes and colors vary from load to load.

What's the difference between cobble and riprap?

Cobble is naturally rounded river rock with a smooth, decorative look. Riprap is angular, so it locks together and stays put better on steep slopes and in fast-moving water.

Is cobble good for erosion control?

It can help in landscape areas and gentle swales. For steep slopes, culverts and fast-moving water, angular riprap holds better because the pieces lock together.

What's the difference between round rock and crushed rock?

Round rock is river rock that's been smoothed by water, so it stays loose, drains well and has a natural look. Crushed rock has sharp, fractured edges that lock together and compact into a firm surface for driveways and pads.

Is delivery included in the price?

Yes. Every price includes delivery, with no separate fees. Pricing is set by location, so choose your town to see the delivered price.

Can you help with drainage problems?

Yes. Along with delivery, we handle excavation and grading work that helps move water away from where it doesn't belong. Learn about our excavation services.
