The implementation of earth blocks in Belgium and Luxembourg: A case study analysis

Abstract

In the search for building materials with a lower environmental impact, there is a resurgence of interest in earth construction. Due to their similarity with conventional materials, earth blocks (EBs) have a high potential to enter mainstream construction. However, to upscale their implementation in practice, better insights into the design and construction process are needed. This paper presents three cases with EBs, both stabilised and unstabilised, and for load-bearing and non-loadbearing applications. Through site visits and in-depth interviews, architects, clients, and contractors are asked to share their experiences on working with EBs and to compare with conventional construction practices. Considerations when choosing EB masonry and specific mortar/block combinations and on-site organisational and practical aspects are mapped. By documenting and analysing real-life cases and comparing with literature, a better understanding of the challenges and practical aspects of implementing EBs in contemporary constructions are obtained, as well as design implications and solutions.
