Damage and restoration technology of historic buildings of brick and wood structures: a review

Abstract

Abstract Historical buildings carry the key technologies and practical values throughout the development of architectural heritage. Investigating the restoration techniques for historical buildings under various forms of damage is an essential step in the conservation and utilization of these structures. Utilizing Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) as the primary databases, this study employs the PRISMA methodology to search and screen relevant research literature. A comprehensive review of the retained literature is conducted, analyzing publication trends, co-citation networks of authors and keywords, among other characteristics. To enhance the visibility of restoration techniques, three-dimensional modeling diagrams are created using actual case information of material or component damage as a reference, thereby increasing the referential value of the review content on historical building restoration techniques. The study provides a thorough review of over 30 restoration techniques corresponding to 9 types of damage from the perspectives of historical building walls and wooden components. Additionally, new materials or technologies mentioned in the retrieved literature are categorized; for instance, in the context of moisture-proof treatment for brick masonry, traditional methods are explained, and new research on electrochemical desalination and lipid-based waterproof materials is discussed and evaluated. Finally, given the multifaceted value and the variable mechanisms of damage in historical buildings, an analysis of the restoration process and techniques reveals that the restoration of historical buildings is a complex interdisciplinary process. The development and implementation of restoration plans should adhere to the principles of cultural relic protection to ensure their reasonableness and effectiveness, while also considering sustainability and environmental adaptability to protect and reuse historical buildings, thus leveraging their cultural and historical values. Moreover, the advancement of restoration techniques for historical buildings in the future should be based on the inheritance of traditional craftsmanship and materials, while also integrating new technologies, materials, and concepts to enhance the applicability and efficiency of traditional techniques.
