In light of the recent media outlets revealing structural waterleakage problems, construction workers, design planners and related enterprises are investing more effort towards forming a solution plan for these issues. This study proposes the structuralization of a information network system that allows the selection and discussion of optimal measures for waterproofing related techniques and expert informations online in a realtime setting.

This study is concerned with the root penetration resistance competence and constructability of a waterproofing and root penetration resistance layer of an eco-bridge which is applied with various types of seeding. For the review of root penetration resistance competence, the competence was tested using herbs, woody plants, and tall trees. As a result, there was no tear of or damage to the waterproofing and root penetration resistance layer as well as the sweeping-down phenomenon of a waterproofing and root penetration resistance layer by soil. Also, the effect of the root growth of herbs, woody plants, and tall trees on the root penetration resistance system was confirmed.

We constructed Seal type waterproofing with adhesive and swelling properties in the field of construction work as yet. But we have many problems of seal type waterproofing with adhesive and swelling properties for construction. Because it has high viscosity, so wokers are too adhered for the work. So, we developed and applied about the high temperature and spray equipments of piston type better than before. We able to be expect that cost reduction and increase construction ability by high temperature and spray equipments of piston type.

In the reinforced concrete structure, Even if speak that water leakage occurrence is no problem to material, there is a lot of reasons construction factor, material damage by behavior structure, properties of matter change by years and water leakage part by environment condition. so, waterproofing technological consideration should be gone ahead. In this research, we will study about stick performance, concrete surface adhesive, damage and blow. we will check all things and test it. The stick expansion type complex of flexible material passed on result of standard. It is conducive to concrete of durability by waterproofing layer performance demobilitation technology on the water leakage structure for solution of problem and repair

Seat waterproofing materials applied to the roof of a building concrete structure inevitably produce joints and are applied with opposite dam joints or overlapping joints depending on the waterproof material applied to the top of the sheet. In this case, the joint performance is determined by the material at the top, rather than by the superimposed joint. In order to solve this problem, various reinforcements have been used to apply to the connecting parts of the opposite dam, but the problem of attachment between different materials or the lack of reinforcement of the joint tape has not been solved. Therefore, for the purpose of securing tensile performance to the joints, this study is used as a reinforcement for the joints of PP materials with high tensile performance and as a reinforcement for nylon materials.

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.

Recently, various maintenance materials and construction methods have been developed to secure the sustainable performance of structures. However, waterproofing of underground structures where groundwater infiltration is present is very difficult. In particular, the location of underground structures such as subways is very deep, and it is difficult to apply waterproof materials and construction methods in the case of structures accompanied by vibration. Therefore, we intend to study materials and methods for waterproofing leakage resistance in special environments such as underground structures.

In the waterproofing of the rooftop of reinforced concrete buildings, it is difficult to solve perfectly according to the proficiency of waterproofing materials, methods, and mechanics. Therefore, this study applies a Tricot Fabric Mesh to the behavior of the bottom concrete. In addition, it responds to the behavior of the concrete cracking, and the waterproofing and protective layer has developed a method to provide convenience for rooftop floor use by adhesion between the base and the waterproof layer with the use of high viscosity urethane to effectively move the surface deformation and surface vapor and install a airvent device on the wall.

In this study, the bond strength characteristics of cement liquid waterproofing are confirmed. Investigation was made on the properties of adhesion strength due to cement liquid waterproof construction methods and changes in curing temperature. It is intended to reduce the possibility of tiles falling off by ensuring the adhesion strength of the cement liquid waterproofing.

In the composite waterproofing method in which a polyurethane coating waterproofing material is applied on the modified asphalt waterproofing sheet, the organic solvent is diluted in the coating waterproofing material in order to improve the workability. However, since the organic solvent is not volatilized before the curing of the polyurethane coating waterproofing material, the organic solvent causes dissolution of asphalt layer, thereby causing oil leakage. As a result, a polyamide film having a high dissolution resistance property was laminated on modified asphalt sheet, and through testing the dissolution resistance was visually confirmed and quantitative analysis of the polyamide film by SEM-EDX analysis was also used to confirmed the dissolution resistance of the polyamide film.
