  • It is socially increasing the need to maintenance of building's durability and management for building's safety. It has happened in waterproofing field, especially in case of water leakage in expansion joint and cracks, lacking basic design for waterproofing. After the completed of construction, there are many troubles something like this. Therefore it need for development to prevent from water leakage, using oakum and urethane in expansion joint and cracks as a method for waterproofing.

  • Domestic residential buidling grading is currently comprised of 5 fields; sound-proofing, structure, ambient condition, living environment and fire-proofing. However, factors the take up most of the civil complaints are related to leakage, and waterproofing is not listed as part of the grading system. In particular, the Ministry of Land and Transport claims that the most crucial problems are leakage related in residential structures. Therefore, this study proposes to provide such grading system for waterproofing by AHP methodology based on waterproofing application locations in residential structures.

  • PHC-W 흙막이 벽체 공법은 연속시공이 가능한 공법이다. 기존 흙막이 공법에서는 지하수의 유출을 막기 위해 별도의 차수공법이 필요한데 반하여 PHC-W 흙막이 벽체 공법은 PHC-W 말뚝의 연결부에 차수제품을 삽입하여 지하수의 유출을 막을 수 있는 공법이다. 이 연구에서는 PHC-W 흙막이 공법에 적용할 3가지의 차수 방안을 선정하여 압력수조 실험을 진행하였다. 섬유팩내에 1액형, 2액형 우레탄을 주입하는 방안에서는 120kPa, 140kPa 이상의 압력에서 급격한 누수가 발생되었으며, 섬유팩내에 그라우팅하는 방안에서는 120kPa 이상의 압력에서 급격한 누수가 발생되었으며 이 방안에서는 차수재의 상단부와 하단부를 우레탄으로 보강한 부위에서 누수가 발생하였다.

  • 본 연구에서는 아스팔트 매스틱 도막방수재를 구성하는 원료의 종류 및 함량을 조정하여 누유발생 특성을 분석함으로써 원료와 누유발생 간 특정 상관관계를 정량적으로 파악하는 것을 목적으로 하였다. 이를 위해 아스팔트 매스틱 도막방수재의 유·무기계 체질안료인 CA(탄산칼슘)와 ASE(침강방지제) 두 개 원료를 선정하였으며, 입도 및 함량을 변수로 설정하여 배합을 통해 샘플시료를 조성하고 샘플시료별 점도 및 누유안정성(20℃, 40℃) 평가를 진행하였다. 평가결과, 누유안정성 및 점도는 CA 평균입도에 반비례하며, ASE 함량에 비례하는 상관관계가 성립하는 것을 정량적으로 증명하였다. 본 연구결과는 향후 아스팔트 매스틱 도막 방수재의 누유 개선을 위한 배합 연구 시 기초 배합설계의 핵심적인 근거자료로서 활용이 가능할 것으로 판단된다.

  • In this study, we would like to study on the application of roof exposure waterproofing method of joint stability through shiplap rubberized asphalt color sheet to complement problem of fracture, exfoliation and water leakage by existing roof exposure sheet waterproofing material joint weakness. Accordingly, examined basis performance and stability for joint that shiplap rubberized asphalt color sheet through test of that tensile strength, bonding strength, water permeability after bonding, peel resistance after bonding, lengthen resistance after bonding and hang resistance after bonding. The results of this study, waterproofing method to using shiplap rubberized asphalt color sheet is judged to solved fracture, exfoliation and water leakage problems happened in joint by problem was joint of exposure sheet by minimizing gap of joint being integration by shiplap.

  • 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.

  • 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.

  • Research has begun to change the waterproofing design of domestic underground structure parts from the current negative-side waterproof design to the positive-side waterproof design. For this, active review from the design stage to prevent the ingress of external ground water into the waterproofing measures of the underground of apartment buildings is needed. Therefore, in this study, proper waterproofing method for the major leaks identified in the previous studies and a waterproofing method for the waterproof design of the underground floor and the outer wall is proposed. It is hoped that a follow-up study, such as a review of field applicability, for the proposed methods will provide an alternative to secure leakage stability in waterproof design.
