In 1993, the Confederated Tribes entered into a joint venture with Structural Technology Incorporated (STI) to develop products from diatomaceous earth. The joint venture Tectonics International, is the first formal business venture between the Tribes (51%) and an off-Reservation company, STI (49%). Tectonics International is charged with the development of diatomaceous earth products, the marketing of those products, and the licensing of the products to manufactures worldwide.

The first licensee of Tectonics International is Warm Springs Composite Products which is 100% Tribally owned.

Because of its fireproof structure, diatomaceous earth material is especially well-suited for the manufacture of cores for fire-proof doors and for the thermally insulative refractory furnace blocks used by aluminum and other industries.
