| Summary: | 碩士 === 國立屏東科技大學 === 土木工程系碩士班 === 92 === Owing to water leaking problems leading to lower resident quality and living torment, leaking parts are always found in roof and bathroom. Although there are diverse engineering approaches for waterproof, construction standards and procedures for waterproof engineering are still in urgently requested. Moreover, due to designer and constructer seem to lack of operation in coordination, there are divergent views on waterproof methods. Therefore, this study aims to propose a survey table set within an investigation method for waterproof construction, through surveying data to present contemporary roof and bathroom waterproof situations. The merits and shortcomings and its suitability of each waterproof methods are also discussed. The results are expected to give some suggestions for the construction industry in Taiwan.
Surveyed data analyzed show that as follows. First, in the aspects of rooftop waterproof materials used, Polyurethane (PU) and Asphalt series are the majorities, which take 56.4% and 25.9% individually. However, the other waterproof materials are seldom utilized. Secondly, about the waterproof materials used in bathroom, PU is mainly used and takes 66.7% in total. Acrylic rubber takes 20.2% and the other waterproof materials are seldom used, either. Asphalt series have the best effect in roof waterproof. PU is suitable for non-working roof and bathroom, while Acrylic rubber only suitable for inclined roof and vertical wall.
Finally, the proportions of waterproof in total construction expenses are described as follows. The expenses of roof waterproof, which includes without and with thermal isolated utilities, take 0.747% and 0.886% individually. Because the proportional range expands widely in rough, evaluating waterproof outgo based on total construction expenses approach is invalid. The proportion of waterproof outgo in bathroom takes 0.239% out of total, and the surveyed cases reveal the consistency. Therefore, evaluating waterproof outgo based on this approach should be more reliable and valid. In this study, new cases constructed after 1996, the average material prices per unit square meters of roof waterproof engineering including without and with thermal isolated utilities are 292 and 688 NT dollars individually. Among these, Asphalt series take 330 and 744 NT dollars per unit square meters individually, and PU needs 291 and 652 NT dollars per individually. The average price of Asphalt series materials is higher less than 15% compared to that of PU material used. The average material price of bathroom waterproof is 256 NT dollars per unit square meters, where PU needs 245 NT dollars per unit square meters
