This present paper mainly contains adhesion part disconnection type exposure composition waterproof method using embossing PVC sheet. The existing polymer resin coating and sheet waterproofing construction method have, however, some weak point such as being decrease life cycle of concrete with water leaking from materials be affected by crack and movement dash bond concrete through the whole-adhere construction. Above the reason, this paper has particular method increasing crack-defending performance from stress occurred concrete movement by part disconnection, adds maintain waterproofing performance subordinate sheet, that can be contributed a convenience of maintenance which is decreasing industrial waste and repair construction cycle through the part repair in case of leaking water.

This study discusses the development of asphalt based waterproofing sheet applied on the blind side of the concrete substrate. The inorganic coating membrane is applied on top of the waterproofing sheet surface for protection, and adhesive bond to the concrete substrate surface is secured via hydration reaction the cement. The study reveals the experimental results of the overlap section tensile strength to observe the effects of the adhesion strength of this material.

Waterproofing materials and construction methods have been developed and applied to various construction sites since the past. However, there many cases where the waterproofing performance is not satisfactory, leading to continuous water leakage. It has been observed that a key reason for this is because waterproofing method and material selection is not optimized in terms of the appropriate application area and environmental degradation factors. This paper proposes that future selection of waterproofing methods should consider the following evaluation criteria; 1) waterproof performance evaluation according to site conditions, 2) evaluation of construction method, 3) manufacturing and maintenance of waterproofing systems.

The purpose of this study is to apply a test method that evaluates durability under wet environment rather than the strength of the material itself to reflect the environment of use and field conditions of silic acid powder applied waterproof material, and to prepare a foundation data for differentiated performance criteria through test verification.

In this study, to overcome the limitation of material application as the surface layer of bridge decks (asphalt concrete, concrete), a newly developed waterproof sheet is proposed to be usable for both asphalt concrete and concrete. Subsequent tensile bond strength was tested, and the test results showed that the tensile bond strengths were similar to depending on the type of the surface layer material for bridge decks, confirming the applicability of the proposed material.

In this study, the performance of acrylate was evaluated by using acrylate composite waterproof sheet. Through this experiment, the waterproof sheet plays a primary role of waterproofing. When the water leakage occurs, the acrylate reacts with water and expands, and the performance of the self repairing of the damaged part is confirmed by temperature.

The water proofing sheet of synthetic polymer applies to the purification plant, the wastewater treatment center, the low waterway, the dosing tanks, etc, and when we construct these, we apply the dual waterproof by means of hot air staking welder or extruder. However, the experts skilled in the hot air welding or extruder does not use them, it can be a quality problem. Therefore, in this study, it is the purpose to verify whether the semi-automatic hot air staking welder and automatic extruder that can construct the waterproof sheet is possible in field even if it is not a professional specialist.

Recently, the use of structure compound waterproof agent (hereinafter referred to as 'SCWA') that is used when manufacturing concrete for concrete structures, increases in quantity. However, while it is expected that the SCWA that is mixed in the concrete inside can significantly affect the change of physical properties that lift the internal force of a structure. This study has been conducted through an experiment for the effects of cement hardener on the formation of microscopic texture, and newly generated hydrates from that result were not confirmed in the present experiment. It was found that at the hydrate reaction it has the property that can be hardened within the limit of pore diameterar a specific size rather than there is the internal gap filling capacity due to generating other hydrates.

Nowadays, energy-saving has become important in the construction industry. Above all things, outside insulation on buildings is important in measure of energy-saving. However, its insulation performance is degraded by the problem of that Cement-polymer modified waterproof coatings are used mostly for covering plaster mortar. In this study, we examine the optimum size of the silica and how does silica's size effect on physical properties of outside insulation covering plaster mortar.

The waterproof construction for walls and floor in the underground parking lot in the construction of the apartment buildings have been excluded to the introduction of the waterproof design until now, because of the shorten construction period and the reduced construction costs. The concrete structures are existed to the joints in the vertical or horizontal parts commonly. In case of cracks, there are generated due to behavior by subsidence and external changing temperature environment. The cracks are generated by the frequent water leaks. So, the repair methods of the water leaks are proposed as the quick micro-cement and the polyacrylic resin in this study.
