Let's connect - SIREWALL® on Social Media


Meror Krayenhoff, inventor of SIREWALL, is one of the top 5 experts in the world on rammed earth. 

When it comes to creating strong rammed earth, thermal detailing of rammed earth, and range of artistic expression, he is widely considered the world’s most knowledgeable.  With 23 years of full time rammed earth experience, few people on the planet know more about, or are as passionate about, the benefits of insulated rammed earth.  Through consulting, Meror enjoys sharing his knowledge to create functional, durable, healthy, environmental, and iconic projects.

Meror is driven by a desire to create a lasting legacy of buildings that work for people and the planet. He is outspoken champion of rammed earth and critical of many current ‘green building’ practices in North America which rely on green-washed standard building techniques.
