Our rock meets the stringent requirements of the U.S. Army Corps of Engineers as well as state and city guidelines. We can deliver high volumes of in-spec armor rock to projects throughout the state as well as Riprap, Levee Fill, River Rock (a.k.a. Streambed Cobbles), and Streambed Boulders.

We’ve supplied many projects to restore and protect shorelines along rivers and streams. Our products have also been used on Midway Island and along the western Washington coastline, Commencement Bay, Lake Washington, and many other bodies of water.
