Question 1

How much gravel will I need?

Accepted Answer

Start by figuring the square footage of the area and the depth of gravel planned. At a 2-inch depth, one ton of gravel will cover approximately 100 square feet as a general guideline. Driveway installations are typically placed 4 to 6 inches deep. For an estimate tailored to your dimensions, try the free gravel calculator. Enter the area's length, width, and depth to see the number of tons needed.

Question 2

How much material may I order?

Accepted Answer

Supply can be arranged for projects from a single ton for a compact patio or garden walk to multi-ton loads for driveways and construction. A ton of gravel spread 2-inch deep covers roughly 100 square feet. Estimate the quantity with our material calculator, or call (206) 582-6792 for help determining the amount.

Question 3

How does gravel arrive?

Accepted Answer

Bulk aggregate orders arrive by dump truck at your property. Tell the driver which accessible location to use, such as the driveway, yard, or another designated area. The truck reverses to the drop point, lifts its bed, and leaves the material in a pile. For smaller areas, spread it with a rake or shovel. Larger areas can be handled with equipment such as a skid steer.

Question 4

Must I be present for delivery?

Accepted Answer

You usually do not need to be present for delivery. Before the delivery date, mark the intended drop area clearly. Cones, flags, and stakes are common ways to show the location. The driver may call if access is not possible or the drop location is unclear. Share any access concerns or special instructions when ordering so they can be passed along to the driver.

Question 5

When will delivery take place?

Accepted Answer

Delivery timing depends on the product and where the order is going, with most orders arriving as fast as 2 business days. Addresses close to metro areas or major supplier hubs can be served sooner, while rural and remote locations can need a little more time. Your order confirmation email will include an estimated delivery window. If materials are needed for a certain date, contact us before ordering and we will do our best to accommodate your timeline.

Question 6

Which gravel should I use for a driveway?

Accepted Answer

Crushed stone and crusher run, which is also called dense grade aggregate, are recommended for driveways. Their angular shape and rough surface help the material compact and interlock, creating a firm driving surface. Typical driveway choices include 3/4-inch crushed stone and 1/2-inch crusher run. Do not use rounded, smooth material such as pea gravel for a driveway, since tires can displace it and it does not compact as well. See the product catalog for materials offered near you.

Question 7

How do pea gravel and crushed stone differ?

Accepted Answer

Small, smooth, naturally rounded stones measuring typically 1/4 to 1/2 inch in diameter are known as pea gravel. It is often used for garden beds, walkways, dog runs, and decorative landscaping because it feels comfortable underfoot and looks attractive. Crushed stone is produced by mechanically breaking larger rock, creating angular edges. Its pieces compact and interlock, which makes it suitable for driveways, foundations, drainage, and structural applications. Choose crushed stone for weight-bearing areas where the material needs to stay put. Pea gravel is suited to decorative or low-traffic spaces.

Question 8

Can you deliver to my location?

Accepted Answer

Delivery service extends across Washington, covering metropolitan areas, suburbs, and many rural communities through local suppliers. Enter the destination address at checkout, and the system will indicate whether that location can be served. For a remote site with uncertain coverage, call (206) 582-6792 and we can review the delivery area.

Question 9

What happens if I order too much or too little gravel?

Accepted Answer

Extra material stays at your property if you order more than needed. Excess aggregate cannot be collected after delivery. It can, however, be used for projects such as filling low areas, edging garden beds, or refreshing walkways. If your order is short, place another order for a second delivery. To help prevent either outcome, use the gravel calculator before placing an order. Ordering about 10% above the calculated amount is also useful for changes in ground level and compaction.

Question 10

Can one order contain different products?

Accepted Answer

Each order currently contains one type of product. Since dump trucks carry material from the supplier, different products cannot be combined in the same load. Order each material separately if your project calls for more than one, such as crushed stone beneath a driveway and pea gravel on a walkway. Free delivery applies to every order, so multiple deliveries do not create an additional cost.

Question 11

How are prices calculated?

Accepted Answer

Your price reflects the material type, order quantity, and delivery location, so it may differ by region. The website displays prices that include free delivery. The amount shown is the amount paid.

Question 12

Which payment methods are accepted?

Accepted Answer

Online orders can be paid by major credit or debit card: Visa and Discover, along with Mastercard and American Express. Payment processing takes place through our encrypted checkout system. Online orders cannot currently be paid with cash, checks, or purchase orders. For payment needs related to a large commercial order, contact (206) 582-6792 to discuss the options.

Question 13

What is the refund policy?

Accepted Answer

An order can be canceled for a full refund before it has been dispatched for delivery. Bulk aggregates cannot be returned, so refunds are generally not available once materials are loaded for delivery or have arrived at your property. If the material is incorrect or there is a significant shortage, contact us promptly at (206) 582-6792. See the refund policy page for complete details.

Question 14

How can I figure gravel quantity for my project?

Accepted Answer

Measure the length, width, and intended depth of the space to be covered. Multiply all three measurements to determine cubic feet, and divide that result by 27 to convert it into cubic yards. A cubic yard of gravel weighs approximately 1.4 tons, so multiply the cubic-yard amount by 1.4 to find the tonnage. You can also use the free gravel calculator instead of calculating by hand. Add your measurements, and it will show the tons required and the cost.

Question 15

What gravel sizes are offered?

Accepted Answer

Stone size refers to the diameter of individual gravel pieces. Standard selections include 1/4-inch (pea gravel), 1/2-inch, 3/4-inch, 1-inch, 1-1/2 inch, and 2-inch stone. Fine material such as pea gravel works well for decorative areas, patios, and walkways. For parking areas, driveways, and general landscape use, 3/4-inch crushed stone is a widely used medium option. Use larger 1-1/2 inch and 2-inch stone for drainage, French drains, and erosion control. Visit the product page to review the sizes and products available for delivery near you.
