Radon rock is a 3/4 inch round rock that works well for both radon mitigation systems and general drainage projects. Because each piece is round rather than crushed, it creates open space between the rocks that allows air and water to move through freely instead of pooling or getting blocked.

Common uses include:

• Radon mitigation systems under foundations
• French drains and perimeter drainage
• Downspout drainage areas
• Base layer under drain pipe

This rock is sold by the ton, and one cubic yard is approximately 1.35 tons. If you want help figuring out the right amount for your project, call us at 509-235-4511!

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