1 1/2″ Basalt Drain Rock is a porous, contractor-grade product built for performance rather than looks. It works well anywhere aesthetics do not matter and the rock will end up buried or hidden underground.

We do not wash this rock, but it stays uniform and free of fines. Because of this, basalt drain rock performs well in drain fields, greywater applications, drywells, and curtain drains. The open space between pieces lets water move through freely instead of pooling or clogging the system.

Common uses include:

• Drain fields
• Greywater applications
• Drywells
• Curtain drains
• General buried drainage 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.
