  • It often happen water leakage that roof membrane have a poor condition such as direct exposed to rain, ultraviolet lays, temperature change compare with other part of waterproofing. There are difficult to maintain the quality of waterproofing and durability due to use only few waterproofing materials in practical in spite of development and use the various waterproofing material as solution of these poor condition. Therefore, in this thesis, I would like to know the property to apply field and suggest other method to develop for this waterproofing method to adopt various field condition for roof tops, as searching exposed and complex waterproofing technology for roof tops which is reinforced sheet using rising system have a regular pitch, depth, space.

  • In the case of conventional ultra-fast hardness membrane waterproofing material (polyurea, etc.), damage such as breakage or tearing occurred frequently at the time of cracking of the surface after waterproofing. In this study, it is suggested that a waterproof layer can not cope with the occurrence of cracks at the same time by applying the soft type waterproofing material of soft type at the lower part of the construction method (securing of elongation) To minimize the possibility of water resistance.

  • Waterproofing techniques used in underground structures do not reflect material and construction environments, but rely only on material properties, which inevitably lead to their limits in durable life. In particular, the government intends to investigate the current underground water treatment method and analyze the problems in order to prevent serious corrosion and aging of structures caused by underground water leaks and poor construction.

  • To measure the effect of the stress-strain dispersion across the installed waterproofing layer on the concrete surface, a strain gauge was attached to the gap between the waterproofing layer and the concrete structure at specified points of upper, center and bottom of the load-displacement simulation specimen, and the peak stress-strain at the displacement interface were measured and compared with stress-strain at other areas to analyze each material types' stress-strain dispersion ratio properties. Based on the results of the testing, it was shown that materials with high load-displacement resistance performance accordingly had high stress-strain dispersion ratio results, and the materials from highest performance to lowest performance were; CAS, SAS, PUC and CSC.

  • The waterproofing system's performance is known to show a determining by complex interaction of material factors, design details, and the qualify of construction, and the waterproofing integrity of waterproofing membranes is determined by the bond to the deck and the amount of damage to the waterproofing membrane. In this research, the basic properties of waterproofing membranes on market and the tensile adhesive characteristics of waterproofing systems of concrete bridge deck have also been investigated in the view of the damages frequently reported from job site. As a results of tensile adhesive strength of waterproofing system, tensile strength is decrease with surface moisture contents except for inorganic-elastomeric liquid waterproofing membrane, and increase with strength of deck slab. Also tensile adhesive strength is generally increase in case of moisture curing of specimen because of pore structure and surface leveling. The after asphalt concrete paving tends to increase more than before those. The results of the liquid waterproofing membranes are upside-down, and the more concrete has strength, the more strength of tensile adhesive increase. The ambient temperature and the rolling temperature of asphalt concrete when application of the waterproofing membrane has considerable influence on the performance of waterproofing system.

  • In this study, tensile adhesive strength(TAS) test was carreid out for evaluated the effects of temperature conditions(-20, -10, 5, 20, 30, $40^{\circ}C$) on the tensile adhesive characteristics about six waterproofing membranes which were commercially used in bridge decks. And, failure appeariences of waterproofing systems in each temperature were investigated and observed the sawing surfaces of waterproofing systems for whether or not damaged of waterproofing membranes. TAS test results were increased when test temperature was decrease in all waterproofing membrane. The type of failure was ductile in $30^{\circ}C$ and $40^{\circ}C$, but brittle failure below $20^{\circ}C$. This results were shown that if temperature above $30^{\circ}C$ is continued for a long time, waterproofing material will be damaged by softening and a part of membranes were damaged by hot aggregate in SMA. So we will consider the type of asphalt for choice of the waterproofing membranes.

  • A general bentonite mate waterproofing material applied salt pollution without particular way(it is a land reclaimed from a sea(or near by sea). Analysis showed that it(general bentonite mate) has a little resistant salt pollution and a little watertightness. There are a lot of problem before completed structure because of salt pollution. So that, they have to a sum of money to repair works. Also, to repaired a part leak water again and again. because it doesn't match for salt pollution. So, I am going to study about a bentonite mate waterproofing material in salt pollution and it will be within the range of possibility to underground structure under the salt pollution. Also, I suggest waterproofing method in salt pollution about workability, stability, economy and etc.

  • 개량 아스팔트 방수시트 위에 폴리 우레탄 도막방수재가 도포되는 복합방수공법의 경우 시공성 향상을 위하여 도막 방수재에 유기용제를 희석해 사용하고 있지만, 유기용제가 폴리 우레탄 도막방수재의 완전 경화 전에 전부 휘발되지 못하고 시트재와 도막재 사이에 잔류하게 되고 이는 아스팔트 층을 융해시켜 방수층 손상 및 누수문제를 발생시켰다. 이에 용제에 의한 융해 문제를 개선하기 위해 내용제성이 강한 PA 필름을 개량 아스팔트 시트에 코팅(적층)하였고, 그 결과 융해에 대한 안전성을 육안을 관찰하였고, SEM 분석, EDX 분석을 통하여 PA 필름에 대한 내용제성을 정량적으로 확인하였다.

  • KS standards mostly relate to single component material evaluation, so in cases of underground structure environments, most cannot predict the existing composite forms of deterioration, resulting in the applied waterproofing materials becoming unable to respond to these damaging factors. Current domestic waterproofing market in Korea mainly uses single-ply waterproofing materials comprised of coatings or waterproof sheets and two or more-ply composite waterproofing methods. In order to evaluate these types of composite waterproofing systems, a new test equipment and method that incorporates various deterioration conditions (joint displacement, chemical exposure, water pressure etc) was developed. In a comparison testing, the results showed that flexible type materials have higher response performance towards joint displacement than the hardened material.

  • The category for waterproofing is one of construction process most affected by falling-off in price competitiveness, construction quality, and material performance. Therefore, in order to select of waterproofing construction firms, it is necessary to consider Incorporating both price competitiveness and construction quality. In this article, I would like to analyze 10 Factors for Selecting using fuzzy-AHP model, including the survey of the waterproofing experts. This fuzzy-AHP model can be shown to calculate the fuzzy trigonometrical function to reflect weights for preference of 10 factors for the waterproofing construction firms. It was found from the result that waterproofing construction firms was searched order of priority for select by fuzzy-AHP model.
