  • This technology is able to construct with hardening UREPALT adhesives and TPO URE-Sheet simultaneously using automatic equipments. the benefit of this construction method is that The layer of waterproofing is uniform and defect of construction would be reduced because of no construction joints between UREPALT adhesives and TPO URE-Sheet. Furthermore, this new method could accomplish shortening of construction period, quality control and saving of labor costs. Also the non-exposure waterproofing method would be protected from fire and safe for workers without using a torch.

  • 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.

  • The goal of waterproofing materials and construction method used for underground structure can be attained only when construction is done perfectly free of laitance, moisture and foreign substances on concrete surface. However, construction engineers agree that it is difficult to perfectly carry out such work in practice and realization of perfect waterproofing for underground structures is impossible in reality. Therefore, this study is to examine and explore waterproofing materials and construction method completely meeting environmental impacts that underground structures receive and thereby suggest waterproofing technology applicable to underground structures, in order to prevent problems caused by leakage for underground structures.

  • Exposed type waterproofing PVC sheets installed on structure rooftops are subject to changes in physical properties after longterm exposure to sunlight. Particularly when consideration the rotational movement of sunlight over the day through the course of the sun rising from the east and setting in the west, in the case of flat roofs the amount of UV ray the the surface of the PVC waterproofing sheet receives may be even throughout, but in cases of slanted rooftops the sunlight exposure may be uneven across the surface. In this regard, this study examines the effect uneven sunlight exposure on the exposed type waterproofing PVC sheets installed on slanted rooftops.

  • This is green roof bottom system which composed by aluminum valve and glass fiber together as major reinforcement, so the cooper sheet can have root proof, and using recycled tire gel-type membrane waterproofing system which dost not contains VOCs. The copper sheet reduce the plants' root growing, so it helpes to maintain the waterproofing layer and stability of root proofing. Gel type membrane waterproofing system can do waterproofing, stress dispersion, and reducing leakage expansion. So those two materials can help each other to make green roof bottom layer would have the stability and durability.

  • Construction projects and buildings are becoming taller and larger, and the size of water tanks of production facilities and high-rise buildings is also gradually increasing. Most large water tanks apply a waterproofing layer to the water tank type concrete structure. The application of polyurea coating materials, which are excellent in water resistance, chemical resistance, physical performance, rapid hardening, and workability is gradually increasing as waterproofing and anticorrosion layer for water tank. As a result, defects such as water leakage and damage to the waterproofing layer are continuously occurring, causing production disruption, setback to users. Therefore, it is required to review suitability through performance verification of the waterproofing and anticorrosion system.

  • This study introduces and demonstrates the application of an experimental regime for anti-seismic performance evaluation of waterproofing materials to used for concrete pile walls. Concrete pile walls are subject to high degree of seismic load, and the occurring stress can affect the waterproofing integrity of the structure, but there is currently no existing methodology or standard for evaluating this property of waterproofing materials. To propose and conduct this evaluation, a new testing apparatus was designed and manufactured intended to be able to test an installed waterproofing material's seismic resistance performance.

  • There is a problem to be solved for improvement of durability and safety supervision. When you do the waterproofing and anticorrosive work of main concrete from the design stage, the material and method of construction need to be correctly applied to appropriate circumstance conditions. Epoxy have mostly been used for concrete water tank structure. Lately, lots of subjects on adaption of polyurea resin waterproofing and anticorrosive are under discussion. Then, we attempt to approach by evaluating and comparing every capabilities with another waterproofs in this study. Performance evaluation items include the adherence performance, the imprint of seal performance, temperature dependence performance, promotion weatherizing ability, inner chemical performance, drinking water eruptive performance. Through the experiment analysis, we found that the polyurea resin waterproofing membrane is dominantly superior to other waterproofs. According to this study, we suggest the polyurea resin waterproofing membrane as a new waterproofing material for concrete structure.
