Our Mission

To advance and promote earthen construction

Our Vision

Earthen construction is 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 Presents!" series, where ECI members and friends give presentations and demos on various aspects of earthen construction and sustainable practices.

Open Board Meeting - 1st Tuesday of the Month

6 pm, Southwest School of Art Bolner Conference Room

300 Augusta, San Antonio, TX 78205
