Our Mission
To advance and promote earthen construction
Our Vision
Earthen construction will be an established mainstream building technology
​
Earthen structures are as old as human history, and some are among the most well known structures on the planet, like the Alhambra and portions of China's Great Wall. ECI was founded by a group of people who appreciate adobe, rammed earth, compressed earth block, cob, and other earthen styles for their sheer beauty, but we also believe that these ancient technologies have much to offer modern humans in terms of comfort, health, and environmental resiliency. ECI exists to bring earthen construction into the mainstream by developing standards and best practices, through research to understand and improve earthen construction, by providing quality resources, and through educational programs and training.
​
You are welcome to join us at our monthly board meetings held the first Tuesday of each month, followed by our Members Present! series, where ECI members and friends give presentations and demos on various aspects of earthen construction and sustainable practices.

It is with deep sorrow that we inform you of the death of our dear friend and extraordinary rammed earth builder Ron Evans Monday afternoon of natural causes. It is too early to determine what memorial arrangements may be planned. More information may be forwarded to you or accessible here on the ECI website at a later time.

Christine is asking for anyone who wants to, please forward any photos or memories of Ron that you would like to share. If you have something, please visit Dignity Memorial.
