Water-immersed concrete affecting floors and walls in interior architecture : A Case Study of the Flood Situation in Chiang Rai Province 2024

Abstract

From the flood situation in Chiang Rai province in 2024, it resulted in damage in waterfront areas that are lower than the main roads. Only wet mud and various items were left that had been damaged. It is difficult to remove from various areas, as well as affecting the concrete structure of the building called water-immersed concrete, causing the concrete to have a reduced bearing capacity and become brittle. Concrete buildings cracked at various points and resulted in a disaster of the building after the water level dropped. In interior architecture, it affects the strength of interior building materials such as floors, walls, and ceiling work. Flooding causes damage. Peeling of the paint and tiles can occur immediately or later in the long term due to the reduction of the strength of the material. The objective of this study was to study the impact of water-immersed concrete on floors and walls in interior architecture: A case study of the flood situation in Chiang Rai Province 2024 by surveying, interviewing, and assisting 2 communities, including: Koh Loi community and Kok Tong community Chiang Rai Province found that after the water level receded, muddy soil was left mixed with various sewages, causing gas in the muddy soil and emitting a bad smell, which may affect safety and hygiene. Therefore, the muddy soil should be removed from the community as soon as possible, and the problem of water-soaked concrete in the building can be solved in case the concrete has a low bearing capacity and can be repaired. However, if the concrete has a large decrease in bearing capacity, it will be difficult to repair, which can be tested by the moisture in the concrete by rubbing it with your hands on the concrete surface. If it is not sandy or there is no concrete at hand, then it can be repaired.
