Rammed Earth
Dominik Abbrederis, Max Weidacher

Dominik Abbrederis was born in Feldkirch/Austria. After a three-year apprenticeship in a sports shop, he traveled and worked as a skiing and surfing instructor. He attended an outdoor guide training in Switzerland and dedicated some years to social work with children in Austria and Portugal. By coincidence, he met Martin Rauch and worked four years in his company Lehm Ton Erde. Taking part in numerous construction projects, he got to know various rammed earth techniques and their particularities. To gain a deeper understanding of earth as a building material, he attended the advanced training Fachkraft Lehm in Germany. Since 2016, he is part of the team of BASEhabitat as a construction manager. In 2021, he started his own company DADO Claywork. da-do.at

Max Weidacher is a craftsman and designer based in Vienna, Austria. He graduated as an architect at the Academy of Fine Arts Vienna in 2012. During his studies, he spent one year in Ahmedabad, India, studying at CEPT University and traveling. From 2015-2017, he studied at BASEhabitat, working on a housing project in Bihar, India. He completed his architecture studies at the Vienna University of Technology in 2024 with a collaborative applied research project in rural Uganda. Parallel to his academic projects, he has worked as a craftsman on various construction sites around the world and conducted workshops on earthen building techniques. Focusing on circular economy in art, design, and architecture, he co-founded the studio zirkacirca.com.

Workshop Content

The new location for the Summer School gives us the opportunity to build something that can stay: a rammed earth wall on the premises of Wissenscampus Kuchl. That’s why this year’s workshop will be organized as a two-week ongoing construction site!

Through the building process, we will cover the topics of material composition and preparation, layout and formwork construction, formwork filling, compacting and protocolling, as well as retouching and finishing. To ensure that all participants can engage in the entire process, the construction will be divided into two phases – week one and week two - which will come together as a whole in the end.

In addition to the practical aspects of construction and the use of various tools, we will also learn how to organise ourselves as a group and coordinate work processes on the construction site.

Workshop Motivation

We are looking forward to continuing our series of workshops at this year’s Summer School. Sharing skills, knowledge and experiences, we are happy to learn with and from each other.

Not only is it another occasion to meet people with all kinds of backgrounds, but it also gives us a chance to pass on a bit of our passion for rammed earth and its potential.

To us, working as a team and with our hands is a truly satisfying experience. We will have a great time ramming some earth together.
