For over 20 years Allied Rock has been a leading supplier of high-quality crushed quarry rock and related materials in the North Santiam Canyon and beyond. 

Our rock is sourced from a naturally formed basaltic flow which makes it the ideal material to create durable long-lasting aggregate for a variety of uses.

From commercial to residential and farming to logging, if you need crushed rock, topsoil, fill dirt, sand, or drain rock, we are your one-stop source!
