Our 4″ Structural fill is a Dow Rocks exclusive product. It is the road base we use on all of our own job sites. This 4 inch minus pit run material gives you an economical way to build up a solid base. It works well as a base for driveways, parking areas, and other large projects.

Because structural fill is a bulk product, it works best as a base layer. Top it with something finer, like our 1 1/4 inch crushed gravel. To complete the build, you can use a top course like our 5/8″ Crushed basalt, which will match the county-grade spec for gravel roads in Spokane.

Common uses include:

• Road and driveway base layers
• Parking areas and equipment pads
• Building up low or soft ground
• Large-scale fill projects

We sell this rock by the ton. One cubic yard equals approximately 1.35 tons. Call us at 509-235-4511 if you want help figuring out the right amount for your project.

Pickup is available at our yard in Cheney, WA, and we deliver in bulk across the greater Spokane area.
