Repairing Concrete: imitating existing concrete surfaces through craft methods
Abstract
Concrete is the most widespread building material in modern construction and has been crucial
to the development of modern architecture, over the past two centuries. However, it has gained a
bad reputation, partly due to its association with the construction boom of the 1960s and 70s and
partly due to environmental concerns.
From environmental and conservational perspectives, concrete constructions have measurable
value; A concrete building represents a valuable resource, containing embedded energy and
natural resources. Therefore, buildings can be viewed as both a resource and a repository of
energy that would be wasted if demolished. The unique properties and construction methods of
concrete are considered culturally and historically significant and tell a story of industrial progress
and architectural innovation. Therefore, concrete should be treated with special attention in
conservation contexts.
Given these challenges, the thesis examines the difficulties encountered in concrete repairs.
Additionally, it explores how craftsmanship can influence the expression of a repair, ensuring it
does not disrupt the overall impression.
In order to answer the research question, interviews with craftspeople working with concrete
restoration were conducted focusing on challenges concerning craftsmanship, sustainability and
conservation-ideology. Experiments were performed to understand the possibilities of imitating
concrete surfaces through craft methods.
The study shows that the challenges faced by craftsmen in concrete restoration encompass
various aspects, including aesthetic, technical, and sustainability related elements. A significant
hurdle is achieving visual coherence between restored concrete and its original appearance,
involving color matching, texture, and patination. Experimentation with different processing
methods, documented through test surfaces, sheds light on concrete's properties and
manipulation possibilities. While the study show that imitation of original surfaces may not
perfectly replicate them due to material and tool variations, the methods presented in the study
can be useful in repair scenarios.
