Who We Are

The Washington Aggregates & Concrete Association, founded in 1959, is a non-profit industry trade association representing sand, gravel, quarry rock, cement, ready mix concrete, related businesses and suppliers in Washington State. The Association is dedicated to strengthening our collective industry and to keep it abreast of the changing way we do business.

The WA State ACI Chapter is based in the Puget Sound / Seattle Metro Area and supports the concrete construction community statewide.  The Chapter conducts dinner meetings from October thru June and focuses on local area project tours, new concrete construction and material technologies, onsite demonstrations, and highlights local projects of interest.


Our 2018 EIC Awards Banquet on Thursday, September 27, 2018 was a great success. click here to see the video!

The 2018-19 ACI Certification Schedule is coming soon. Check our calendar for upcoming dates.

We are looking for help on the Safety Committee  and the Workforce Development Committees.  Contact our office for more info!
