How Much is a Load of River Rock?

The cost of a load of river rock varies considerably depending on several factors, but generally, you can expect to pay between $25 to $150 per cubic yard delivered, not including potential delivery fees. These factors range from the rock’s size and type to your location and the quantity purchased.

Understanding River Rock Pricing

Determining the precise cost of a load of river rock involves dissecting several variables. Unlike commodities with fixed market prices, river rock prices are heavily influenced by regional availability, transportation costs, and the specific characteristics of the rock itself. Let’s explore these elements in detail.

Factors Influencing the Price

Rock Size and Type: Smaller river rocks typically cost less than larger ones. Exotic or specialty river rocks, often imported or sourced from unique geological formations, will command a premium compared to common, locally available varieties. For example, polished pebbles or uniquely colored river rock used for decorative purposes will be significantly more expensive.
Quantity: Purchasing in bulk usually translates to lower per-unit prices. Suppliers often offer discounted rates for full truckloads or multiple cubic yard orders. Contacting multiple vendors and comparing quotes for various quantities is advisable.
Location: Transportation costs significantly impact the final price. Regions with abundant local sources of river rock will generally have lower prices than areas where the rock needs to be transported long distances. Fuel prices and labor costs at the quarry or supplier also contribute to these differences.
Supplier: Prices can vary widely between different suppliers. Local landscaping supply companies, quarries, and even home improvement stores may offer river rock, but their pricing structures will differ based on their overhead and sourcing strategies.
Delivery Costs: Many suppliers charge a separate delivery fee based on distance. Some may offer free delivery within a limited radius. Be sure to clarify delivery charges before placing your order.

Estimating Your Needs

Before requesting quotes, it’s crucial to accurately estimate the quantity of river rock you need. This involves measuring the length, width, and depth of the area you intend to cover. Use the following formula to calculate the volume in cubic feet:

Volume (cubic feet) = Length (feet) x Width (feet) x Depth (feet)

Once you have the volume in cubic feet, divide by 27 to convert it to cubic yards:

Volume (cubic yards) = Volume (cubic feet) / 27

Always order slightly more than you estimate to account for settling and potential spills during delivery. It’s always better to have a little extra than not enough.

FAQs: All You Need to Know About River Rock

Here are some frequently asked questions to help you navigate the complexities of purchasing river rock:

What is the difference between river rock, pea gravel, and crushed stone?

River rock is naturally rounded due to water erosion, making it ideal for decorative purposes and drainage. Pea gravel is also rounded, but smaller (typically ¼ inch to 3/8 inch). Crushed stone, on the other hand, has sharp, angular edges and is often used for driveways and construction projects where compaction and stability are required. The cost of each can vary slightly, with crushed stone often being the least expensive.

How much does a cubic yard of river rock weigh?

A cubic yard of river rock typically weighs between 2,700 and 3,000 pounds (approximately 1.35 to 1.5 tons). The exact weight varies depending on the size and density of the rocks. Ensure your delivery location can handle the weight of the load.

Can I pick up river rock myself to save on delivery fees?

Yes, many suppliers allow customers to pick up river rock. However, consider the weight capacity of your vehicle. A pickup truck can usually handle a relatively small amount (e.g., half a cubic yard), but a larger quantity will likely require a dump truck or trailer. Renting a trailer may be more cost-effective than paying for delivery in some cases.

What size river rock should I use for my project?

The appropriate size depends on the application. Smaller river rocks (1-2 inches) are suitable for pathways, gardens, and dry creek beds. Medium-sized rocks (2-5 inches) are good for erosion control and drainage. Larger rocks (5 inches and up) can be used for decorative features like waterfalls or retaining walls.

What are the common uses for river rock?

River rock is versatile and can be used for a variety of applications, including:

Landscaping: Decorative ground cover, garden borders, pathways, and dry creek beds.
Drainage: French drains, erosion control, and around downspouts.
Construction: Concrete aggregate, landscaping accents.
Erosion Control: Helps stabilize slopes and prevent soil erosion.

How can I prepare the area before having river rock delivered?

Clear the area of any debris, vegetation, or existing materials. Grade the surface to ensure proper drainage. Consider installing landscape fabric to prevent weeds from growing through the river rock. Clearly mark the delivery location for the driver.

How do I calculate how much river rock I need for a specific area?

As outlined above, measure the length, width, and desired depth of the area. Multiply these dimensions to find the volume in cubic feet. Divide by 27 to convert to cubic yards. Remember to add a small amount extra to account for settling.

Does the color of river rock affect its price?

Yes, certain colors or color combinations of river rock may be more expensive. Naturally occurring colors like gray, brown, and tan are usually the most affordable. Rarer colors or artificially dyed river rock will typically cost more.

How do I clean river rock that has become dirty or discolored?

You can clean river rock using a pressure washer or a mixture of water and mild detergent. For stubborn stains, use a scrub brush and rinse thoroughly. Avoid using harsh chemicals that could damage the rock or harm the environment.

How can I find a reputable river rock supplier?

Ask for recommendations from friends, neighbors, or local landscapers. Check online reviews and ratings for local suppliers. Contact several suppliers and compare prices, delivery options, and customer service. Ensure the supplier has a good reputation for quality and reliability.

What are the advantages of using river rock over mulch?

River rock is durable, long-lasting, and requires minimal maintenance compared to mulch. It provides excellent drainage and can help control erosion. However, it can also retain heat, which may not be ideal for all plants. River rock also doesn’t decompose and enrich the soil the way mulch does.

Are there any environmental considerations when using river rock?

Sourcing river rock can have environmental impacts, such as habitat disruption and energy consumption for transportation. Consider sourcing river rock from local suppliers to reduce transportation costs and support local businesses. Also, ensure the quarry from which the rock originates adheres to responsible mining practices. Choose sustainably sourced and environmentally friendly options whenever possible.
