RAMMED EARTH WALL
Chair of Building Construction, RWTH Aachen University, 2015
As part of a seminar for Master’s students, we investigated the basics of building with small-format rammed earth blocks. Following on from a first part of the seminar and the study of various element geometries, an exemplary wall structure - consisting of 170 elements previously produced using individual formworks - was implemented as a temporary installation in front of the main entrance to the Faculty of Architecture.

Building on earlier research on rammed earth, the dissertation deals with erosion control measures for weathered rammed earth masonry. By means of theoretical, design-based and practical investigations, an overview of various functional and aesthetic potentials is provided. The core result of the thesis is the theory of steered erosion, which describes different ways of intervening in the erosion process as possibilities for adapting the degree of protection to local requirements as well as utilizing the special design-related quality of erosion.

The task in this project was the design of a pavilion building on the grounds of a municipal zoo, which was to provide a meeting room for small groups of visitors, a covered outdoor area, as well as a kiosk and ancillary rooms. Being an experimental building for the testing of rammed earth masonry, the rammed earth walls were only to be designed as self-supporting, while the roof structure rests on a wooden supporting structure.

In a series of research seminars, we investigated strategies for reducing surface erosion in weathered rammed earth surfaces. Here, the focus was on strategies for braking vertical water runoff, such as by corrugating the surface or optimizing the surface texture. For each strategy, different implementation variants were considered and test wall sections were created for them. A subsequent rough simulation of the natural erosion process by artificial sprinkling allowed an evaluation in functional and aesthetic terms.
Lehmlabor investigates future potentials of clay and earth as building materials. Our field of activity includes experimental investigation of architectural aspects in the context of research and teaching, as well as the implementation of new findings in planning and building practice.
Lehmlabor was founded by Philipp Hoppe in 2021. Previously, Philipp worked as an architect for, among others, hg merz (Stuttgart, Germany) and Junya Ishigami (Tokyo). From 2013 to 2019 he was a Research and Teaching Associate at the Chair of Building Construction
at RWTH Aachen University, Germany.
