Analysis and evaluation of solutions for reverse waterproofing caused by capillary action in newly built brick masonry walls: A comparison between Vietnam and international practices

Abstract

The deterioration of construction works due to leakage has always been a pressing issue, leading to numerous health, economic, and social consequences. These issues have not received adequate attention in the standards and regulations in Vietnam, especially regarding reverse waterproofing in masonry walls caused by capillary action. This paper analyzes and evaluates the current state of domestic standards and regulations, as well as their practical application in construction projects, while comparing them with international regulations to propose solutions suitable for local conditions. Relevant domestic and international documents were compiled, analyzed, and compared. The study reveals that Vietnam lacks guidelines for reverse waterproofing in newlyconstructed masonry walls affected by capillary action in terms of design, construction, and acceptance. Construction companies are currently employing self-developed or adopted methods. In contrast, international standards provide specific regulations for this process. Therefore, this paper proposes solutions for inclusion in Vietnamese standards and guidelines based on the best technical and economic criteria.
