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.

Insulation in buildings are one of the crucial factors for energy reduction, and depending on the application areas and properties of the insulation requirements, various different types of insulation materials are being developed, produced, and used. Amongst these is the aircaps often used as packing materials. Because of their porous nature, they are highly efficient in preventing heat and are consequently used overseas often as insulation materials and as part of cold water concrete insulation curing method. This paper studies the recently developed usage of aircaps in waterproofing materials and evaluated their performance as supplementary insulation materials.

The subject of this study, Eco-friendly Polyurethane Waterproofing Membrane Coating of Exposed Type is manufactured by replacing environmental hazardous substance such as Toluene, Dioctyl Phthalate with Dimethyl Carbonate, waste-soybean oil. As part of existing filler is also replaced with waste-rubber chip and waste-soybean oil. As a result of environment friendly tests, in test of detection of VOCs case was contented with the Ministry of Environment standards at 5% below. Testing methods for heavy metal extracted was contented with standards for official wastes test method. So it is judged that environment friendly is secured.

This study is conducted for prevent spread of penetration water and water leakage through non-woven fabric between PVC sheet and PVC sheet in the PVC composite waterproofing sheet of a multi-layer structure. For this, carry out absorption amount test to confirm spread resistance performance after manufacturing PVC composite waterproofing sheet of a multi-layer structure using water-repellency processed non-woven fabric. As a result of test, weight of water-repellency processed non-woven fabric increased to 1.178g, Compared with beginning and there are not penetration water.

Integrated water-soluble film is dissolved in the rubber asphalt waterproof sheet to secure adhesive strength on freshly cast concrete on the adhesion side of waterproofing layer on the floor slab. In addition, in order to determine whether the water in the concrete slurry can dissolve the water-soluble film sufficiently, the adhesive strength of the waterproofing sheet was compared between difference wetness condition at the upper part of the concrete specimen before the concrete casting.

Installation and usage methods are currently different between China and Korea for the same rubber asphalt waterproofing sealant. Quality verification is not properly carried out in this situation, so it is necessary to secure reliability in order to export domestic materials to China. In this study, rubber asphalt waterproofing sealant used as injection-type leakage repair material was tested in accordance to adhesion strength quality test method outlined in the JC/T2428 Chinese Industrial Standard to confirm the basic performance is compliant or not.

In this study, in the coating-sheet composite waterproofing method, a specimen was formed to prevent the transmission of the no-node tensile stress occurring under the junction between sheets by forming an insulating structure when the junction was formed, and to compare the effect of preventing breakage with the existing common junction. For this, tensile performance evaluation was conducted. As a result of the evaluation, it was confirmed that it exhibited higher tensile strength compared to the existing joint and at the same time exhibited a large width of displacement characteristics, and thus, had an effect of preventing breakage.
