About river rock
River rock is mostly decorative and for drainage beds. It is not meant to be driven on and tends to roll if used as a walking surface.
Hauling 13 yards
At about 17.6 tons, this is more than one typical truckload. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.
Before you order
- Confirm whether the yard prices river rock by the ton or by the yard.
- Add about 10 percent for compaction and uneven ground.
- Clear a firm spot for the truck to dump.
The volume and tonnage calculator converts any area and depth into yards and tons.
Where river rock fits
Best suited to:
- Dry creek beds and drainage swales
- Decorative borders and planting beds
- Around downspouts to stop splash erosion
Poor fit for:
- Walking surfaces
- Driveways
- Bases under slabs or pavers
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of river rock (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 20x25 area at 2 inches takes about 4.2 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
