About Us

Under new ownership and management since June of 2019, we have been striving to and have succeeded in manufacturing all types of quality construction aggregate materials. Our focus is a solid supply of quality products that you can trust to be available, meet your needs and any required specifications.

With a large fleet of trucks available, our Johnson Creek Quarry in Tenino and our sand and a gravel pit in Roy, give us a service area that extends from northern Lewis County into southern King County.

Our 167 Stockpile Site off Levee Road in Puyallup provides you with a well maintained, quick in and out, location to dump all your Class 1 soil. No job is too large for us to handle. The site can be manned 24 hours per day for your convenience.
