Kauai Aggregates


Kauai Aggregates is a Kauai family owned and staffed rock products company, operated continuously by Olaf Thronas and his family since the company began in 1982.

We produce aggregates for our key customers, O Thronas Concrete and Grace Pacific Corp, as well as for many valued contractor and homeowner customers.  We supply ASTM, Hawaii State, and Kauai County specified rock materials, and we will gladly produce custom products to any size or specification.  We have supplied quality aggregates for many large projects on Kauai, government and private, and for all sizes of homeowner projects as well.

Please give us a call for price quotes, or to ask any questions you may have regarding rock products.  We eagerly look forward to serving your needs.

We are located makai of the Wahiawa Gulch Bridge on Halewili Road, between the Kauai Coffee Visitor’s Center and Eleele/Port Allen.
