The number of defect disputes occurring in apartment houses is increasing year by year, and among them, disputes caused by defects in tiles account for 28.2% of the total, which is an important defect in tiles. A representative tile defect in the defect dispute is the lack of tile backfill. Another dispute occurred that the standards for each organization are different as the 100% standard of the Ministry of Land, Infrastructure and Transport's building construction standard and 80% standard of the Architectural Institute of Korea's Building Technology Guidelines. In this study, it was analyzed the relationship between the amount of tile backfill and the amount of tile defects based on 100 defect litigation court appraisal documents. It was observed that the amount of defect in tile works tended to decrease as the amount of tile backfill increased. By presenting an appropriate amount of mortar to fill behind tiles in a defect dispute, the effect of reducing the defect dispute can be expected.

Tile defects in apartment houses are caused by a combination of various factors. These factors cannot be specified, and it is difficult to determine the exact cause because a number of causes are intertwined. In addition, because the climate of Korea is different by season, the coefficient of thermal expansion between materials is different, which is a major cause of tile defects. Therefore, this study analyzed the difference between the construction location and the period of defect occurrence according to the types of tile defects caused by environmental differences between indoor and outdoor environments. Two-way ANOVA was used, indoor and outdoor spaces were selected, and defect types were selected accordingly to show the difference in the occurrence period of each defect.

Recently, bathroom tile defects in households are occurring more frequently. Until now, the destructive investigation method has been required to analyze tile defects. This study proposes a non-destructive using a thermal emission camera imaging as a possibly more precise method of investigating tile failure compared to previous existing methods.

The area inside the apartment building where tiles are installed is applied as a finishing material for walls and floors, including exterior walls, balconies, hallways, bathrooms, and kitchens. As it is constructed in various spaces, differences in the type and period of occurrence of tile defects may appear, which is caused by heterogeneous characteristics between materials and external causes. Therefore, in this study, two-way ANOVA was used to figure out the relationship between the defect occurrence type and the period depending on the type of tile construction in the apartment building.

The objective of this research was to engineer a tile module that could efficiently curtail the incidence of tile defects during the construction phase. To assess the potential diminution in defect manifestation, we executed experiments centered on surface condition, the variation in mass before and after the freeze-thaw test, and adhesive strength. Our findings demonstrated that thermal contraction and expansion induced a relatively escalated frequency of defects in the underwater setting for the aluminum mesh, while the steel mesh saw a higher defect incidence in the air environment. Additionally, it was noted that the adhesive strength exhibited a trend towards augmentation as the mesh size dwindled. Collectively, these results suggest that the employment of smaller mesh sizes can foster improved adhesive strength, consequently diminishing tile defects. Further exploration and development of the tile module, informed by these insights, can substantially enhance the efficacy of the construction process.

In modern architecture, tiles are used as a decorative material to enhance the appearance of buildings. However, defects occurring during tile installation affect not only the appearance of the building, but also its maintenance. This study aims to investigate stable tile installation by producing tile modules using the floating mortar method and conducting freeze-thaw tests to measure their adhesion strength. Test results showed that the adhesion strength increased as the mesh size decreased, except for S3 mesh. This study highlights the importance of research on tile installation to solve problems related to building appearance and maintenance.

The rear side surface of tiles act have protrusions that helps secure the adhesion between the tile and the mortar for tile setting. Conventional height of the rear side usually ranges between 1 to 1.5 mm, and the molding method is classified in between press type and compression type during the manufacturing process, with most tiles being produced by the former method. In sites where adhesion failures were observed, tiles were taken to examine the cause of defect. It was determined that height was irregular at the rear side surface. Based on these findings, an experiment was conducted to determine the correlation between the rear surface and the bonding strength of tiles.

As the domestic housing supply problem has been resolved, the apartment construction market has shifted to a consumer-oriented market that wants high quality, and in particular, expectations in the area of finishing quality have increased. Looking at the status of complaints regarding apartment housing defects supplied by Korea Land and Housing Corporation, tile-related complaints are the type occurring the most frequently. While the Ministry of Land, Infrastructure and Transport(MOLIT) is making an ongoing effort to reduce complaints related to defects, through approaches such as drafting amendments to 「Investigation of defects in apartment houses, calculation of repair costs, and standards for determining defects」, the provision of preventive measures has been insufficient. In addition, by reviewing studies, there has been insufficient research to construct a classification system after deriving the characteristics of each type using the qualitative knowledge of experts, various quantitative indicators, and suggesting measures for reduction according to the causes of each type. Therefore, this study will reflect qualitative indicators to use the AHP analysis that makes it easy to identify the relationship between defects by surveying construction experts. Then, by visualizing the weight of 'Possibility of recurrence after repair,' 'Degree of difficulty in repairing defects' and 'Fault frequency' using a radial graph, we will analyze the characteristics of each type of tile construction defect and establish measures for reduction according to the cause. This will improve the quality of the living environment and contribute to the establishment of a system for smooth defect management and reduction of defects in apartment tile construction.

In this study, although the diversity of tiles in the expanding housing market is increasing, cases of defects in building interior tiles that occur due to limitations of existing tile adhesives and construction methods were collected, and among them, the relationship between the coefficient of thermal expansion and the occurrence of defects was analyzed. One-way ANOVA was used for the analysis method, and as a result of the analysis, it was analyzed that the difference between groups in temperature difference and humidity difference by defect type was significant.
