Buy Gravel & Rock in Saint Helens, Oregon

Saint Helens gets about 47 inches of precipitation a year, so drainage and washout planning matter more than in drier parts of the state. The size you choose for a gravel or rock project controls how water moves through the layer and how well the surface holds up under traffic.

Gravel Monkey ships all the common sizes by the ton to any address in the city and around Columbia County. You order online, pick a delivery window, and a dump truck brings the load to your site.

Gravel and rock sizes stocked in Saint Helens

The product you pick depends on traffic, drainage, and appearance. Crusher Run and Road Base are the ones to start with for a compacted base; River Rock and Pea Gravel are decorative. Every material is sold by the ton and can be ordered for delivery to your address.

Which material to order for common Saint Helens projects

The project determines the product and the depth. Use the table below as a starting point, then check the material calculators on the site for exact tonnage.

Working with gravel and rock in Saint Helens weather

About 117 days a year bring at least a tenth of an inch of rain, so scheduling a delivery onto firm ground takes planning. If the ground is saturated, the truck tires can rut a lawn or soft driveway. Choose a dry stretch if you can.

Freeze and thaw cycles work on loose material all winter, which is the argument for the deeper first lift. Saint Helens sees about 66 days a year below 32F. A deeper base layer of Crusher Run or Road Base helps resist frost heave and keeps the surface from shifting when the ground thaws.

The ground around Saint Helens is mapped in hydrologic group D, which means it takes water in very slowly, so most rain runs across the surface. That makes drainage a bigger concern here than in areas with sandy soil. On a driveway or path, a 4-inch base of compacted Crusher Run with a crowned surface sheds water better than a thin layer. Snowfall averages about 1 inch a year, but even a light snow can cause plowing damage to a loose gravel surface if the blade digs in.

How to estimate how much gravel or rock you need

Coverage depends on the stone size and the depth you spread it. A cubic yard of most gravel and rock weighs about 1.3 to 1.5 tons. Use the material calculators on the site: enter the project area and depth, and it gives back tons. That number is what you order at checkout.

Frequently asked questions about gravel and rock in Saint Helens

How many tons of gravel and rock do I need for my project?

The tonnage depends on the area and depth you plan to cover. Saint Helens gets about 47 inches of precipitation a year, so a deeper layer is often better for drainage. Use the material calculators on the site to get an exact number for your specific project dimensions.

How much does gravel and rock delivery cost in Saint Helens?

Delivery is priced by ZIP code at checkout. Columbia County permitted about 47 single-family homes in 2024, so new construction deliveries are common. Free delivery is available on qualifying orders. No other cost figures are available from the site.

How far in advance should I order?

Orders must be placed at least 3 business days before the delivery date. Choose a morning or afternoon window at checkout. The truck arrives within that window.

What is the difference between the sizes you stock?

Smaller gravel like 3/8" Pea Gravel works for walking surfaces and play areas. Larger sizes like 2-4" River Rock handle erosion control and decorative cover. Angular crushed materials like Crusher Run and Road Base compact into a firm load-bearing base. The right size depends on whether the surface needs to shed water, carry traffic, or both.
