Recently it is considered generally the cost influence to the selection criteria of materials to improve service life the public RC buildings. Many public RC buildings were built in high economic growth period, over thirty years ago. In this duration, it was provided many defects. Many of primary school buildings are RC structures, and the deterioration of their exterior walls are more noticeable than the deteriorations of building frames. These buildings need to be improved. In this study, the present condition based on investigation of actual conditions had been done and, repair for long-lasting buildings and calculations about life cycle cost are considered. It if found, the most of the primary school buildings have many problems at the exterior walls by field survey which had been done in Maebashi district by authors. For these reasons, it is important that to calculate a life cycle cost (the total cost from planning stage till demolition stage) for solve problems efficiently. The selection criteria of materials will be changed if it is planned to be used school buildings for a hundred years. Also it is desired the repair cost would be reduced. Lastly, till several ten years, the total cost of seal method becomes more expensive than epoxy injection method. Consequently, the cost burden will ease by the selection criteria of materials if we consider the life cycle cost.
