Round Rock for Drainage and Landscaping

Whether you need drainage products or landscaping solutions, our round rock products do the job in style.

Round Rock Products Overview

Landscaping Applications
For dry creek beds, many customers use River Rock, Streambed Boulders, and Streambed Sediment. If you need help determining which products to use, you can send us a message through our quote request form. Our products have been used for running water features as well.

We also supply Drain Rock and River Rock for garden borders and edging.

Playground Materials
Pea Gravel is a popular choice to fill playgrounds. We can also supply 7/8” Drain Rock if you want a larger product. Check out a playground before/after photo with tips on getting the right product type and quantity for your playground.

Drainage Material
Drain Rock can be used as a fill material around pipes. Drain Rock and River Rock can also be used strategically where gutters drain or where water erosion naturally occurs. Learn more about erosion solutions in our blog article “Preventing Erosion.”

Check out our Backfill Gravel product page for more drainage options.

Concrete Aggregates
Concrete Aggregates are graded especially for concrete and asphalt manufacturers.

Fish Habitat and Streambed Restoration
Washington Rock is one of the few suppliers in Washington State that can customize streambed products to individual creek, wetland, river, and shoreline restoration projects. Contact us for a free quote.

Streambed Boulder Pick Up Orders
We require appointments for all streambed boulder pick-up orders. You can contact dispatch to set up an appointment.

Please note that due to federal mine safety regulations, we no longer allow residential customers to hand select boulders on the mine site.
