Providing The Highest Quality Products And Services Since 1947


As a manufacturer and distributor of essential construction and infrastructure products, we continue to remain open.

With Washington State opening Spokane County to Phase 2, we are implementing a few changes to make your experience working with us a little easier.

We are still not business as usual.  We take the health and well being of our employees and customers very seriously. We have implemented protocols to ensure the safety of our employees and customers as we continue to face the Covid-19 health crisis and working within Washington States requirements & CDC Guidlines.

Our office is Limited to 2 Customers at a time.  Our office showroom is small, we ask that you keep the 6' social distance at all times.  We have added plexi-glass at our sales counter to limit exposure.

Entry into the office is through our side office door on the east end of our building.

This will be one way traffic, with exiting through our front door facing Trent Ave.

You can still call your orders ahead of time to our office at 509-534-0651.

As you are loaded please keep the 6 foot social distance from our employees. 

If you have any questions or concerns, please feel free to call us.

Thank you for your patience and understanding.

The White Block Crew

White Block Company, Inc. was founded on February 20, 1947 by twin brothers Edward and Harold White. After being honorably discharged from the Army after World War II , their original plan was to open a heavy duty truck & equipment repair shop. But due to the lack of building materials in the area, they decided to invest in a hand operated block machine that was capable of producing 600 concrete masonry units per day. The blocks sold as fast as they were made, indicating they had made a wise decision. Over seventy years later, the plant has tripled in size and currently covers over ten acres. White Block Company can produce over 28,000 concrete masonry units per day at full capacity. We can manufacture over 200 different types of block on our Besser V12 machine. Some examples of what we make are Smooth Standard Units, Architectural Splitface & Groundface Units, Allan Block and Stonewall Retaining Wall Units, Chimney Block and a number of Specialty Block. Through the years we have added a full line of pre cast materials such as Parking Bumpers, Drywells, Catch Basins and Septic Tanks. White Block Company also carries a full line of masonry accessories including tools, sacked goods, masonry cleaners and sealers, and other miscellaneous building materials.


In 2020, we are celebrating our 73rd year in business supplying Masonry, Landscape and Precast products to our customers and the Inland Northwest.


We look forward to working with you on your project!  Give us a call or come by, we are happy to help!
