Course FAQs

What will students learn by taking a course?

Students will learn exactly what they came to learn. It is extremely rare that participants leave with unanswered questions, despite some of them coming with very long lists! The main benefit to the amount of group-learning we offer is that participants leave with answers, even to questions they hadn’t yet thought to ask.

Who are the courses designed for?

The courses are designed for people from all walks of life.

Those who have already benefitted from our courses include:

  • architects
  • building inspectors
  • developers
  • DIYers
  • engineers
  • environmental ambassadors
  • first-time builders
  • green-building enthusiasts
  • interior designers
  • technologists
  • tradespeople.

What people get out of the course is driven by what they want to learn. For some people the engineering segment is the most interesting, while others benefit most from touring houses we’ve built.

Some people love the networking with like minded individuals, while others are moved and enlightened by the depth and breadth of our green conversations.

Those who continue on to the practicum gain a deep and tactile understanding of the inherent pleasure in building in a way that not only aligns up with their values, but that is also a fun team-based endeavour.

What is shared by almost all participants is the realization that what is now possible in building goes far beyond what conventional building offers.

Why do you teach SIREWALL?

We became disillusioned with conventional homebuilding and made the move to SIREWALL. It is so important that people stop building toxic, disposable homes as such practices wreak havoc on the environment and are largely responsible for climate change. Building with SIREWALL is a sustainable solution that can lead to positive change, and we’re passionate about spreading the word.

What is SIREWALL?

SIREWALL is a proprietary engineered sandstone wall – capable of extremely high strength for nearly any structural or decorative application, with high R-values for superior thermal performance in any climate region. Simply put, it is rammed earth reconsidered and brought into the modern age.

How is SIREWALL superior to other forms of rammed earth?

The SIREWALL system relies upon a series of advances protocols that make rammed earth strong enough to compete with concrete as a structural material and thus make it possible to design anything from a small garden wall to large commercial buildings with the many beneficial qualities of rammed earth, previously only available to residential construction. SIREWALL Inc.’s technology is the only rammed earth system in the world capable of tall, load-bearing commercial applications, and it outperforms other types of rammed earth in many other ways — learn more at SIREWALL.com. (link opens new tab).

The longest, tallest and strongest rammed earth walls in the world are all SIREWALL.

Your goal may not be to build a 100-foot tall rammed earth tower, but this technically rigorous course will give you an intimate understanding of how and why rammed earth works—and what it takes to make it great, at any scale!

“Rammed earth is easy to do—but difficult to do well.” –Meror Krayenhoff, SIREWALL inventor
