Rammed Earth Made Easy with Watershed Blocks – By Michaela Harms

In the 1970’s David Easton began his innovative work modernizing rammed earth building techniques toMichaela Harms fit into California’s stringent building codes. Despite his success with Rammed Earth Works, David noticed that rammed earth was a hard wide-spread sell because engineers were apprehensive to understand it and upfront cost-focused contractors did not want to wait through the lifecycle for its benefits. He decided to make sustainable impact by focusing on a more familiar and lower cost alternative, which led to the development of the Watershed Block.

David’s company, Watershed Materials supplies low-concrete masonry blocks that are used like common CMUs, concrete masonry units, with half the embodied energy. By piggy-backing onto the already known CMU standards and uses, these blocks are an easy-to-sell green alternative. Watershed Blocks have many of the same benefits as rammed earth including long lifespan, high thermal mass, and natural material use at a much lower price.







“I like to believe we are not only reducing carbon in our atmosphere, but saving a time honored building technique” adds Watershed employee, Dan Alvarado. Revitalizing the art of masonry is a great asset of this company as they open up a sustainable job market for these skilled craftspeople. The beauty of the natural colors of the local aggregate that make up Watershed Blocks is apparent in the pixelated masonry walls they create that attract architects and designers. When speaking of his favorite building material, earth, Dan states “there is a character to earth buildings that is hard to define. You feel connected to it, protected by it.” That connection is essential to sustainable structures and truly unique to buildings of natural materials.

Watershed Blocks are still a little more expensive than their CMU counterparts but the company projects that improvement in production and inevitable larger market adoption will lower retail prices. If more companies consider full life cycle costs, the savings are apparent even now. Green materials that supply LEED points are already desirable and Watershed is clearly getting noticed, recently being selected as a finalist for SXSW’s Eco Startup Showcase Competition.  As more companies like Watershed modernize and familiarize natural building techniques the beauty and health of our built environment will benefit.

Micheala: Summer 2014 Intern Extraordinaire

Michaela is a student at Metropolia University in Helsinki, Finland studying sustainable building engineering. Her interest in innovative building was sparked with an initial project in the Mojave Desert at Aquarius Ranch on a super adobe dome underneath UFOs and starry skies.

She stumbled into the natural building world through working on organic farms and continued on with projects utilizing cob, light-clay straw, adobe, and infinite recycled materials. After working at cafes and arts non-profits to support her wanderlust, she chose to return to the Nordic region to get back to her building passion.

This summer she was on work placement with Whole Trees Architecture in her native Wisconsin with one of her architectural heroes, Roald Gundersen. In the future she hopes to creatively develop accessible hybridized building techniques. She believes natural materials, inspiring integrated design, cradle-to-cradle material reuse, and updated vernacular architecture are the future for a sustainable built environment.

When she’s not brainstorming building compositions and calculating structural integrity you’ll find her biking aimlessly, foraging in the forests, enjoying beers at a sauna evening and flipping around with her acrobatics group.

Micheala researched and wrote many articles while interning at The Reclamation Administration.
