  • The purpose of this study is to present the optimum performance of hybrid waterproofing technology, which is including material and construction method. Recently, Hybrid waterproofing technology is developed little by little in KOREA. But there is not any other criterion of performance and evaluation of this technology. So, It is needed that appropriate performance items is are settled urgently. This paper were obtained by the SPSS analysis. In this study the safety factor are more important performance of building waterproofing materials than durability comfortability and productivity. And results of this analysis showed that (1) safety performance consists of Fatigue resistance, Crack Control performance deterioration Processing of tensile performance, Compressive Strength test (2) comfortability performance consists of watertightness, bond performance (3) persistency performance consists of abrasion resistance, tensile performance, flexural strength (4) productivity performance consists of dimension, unit space weight.

  • The problem of water leakage due to damaging waterproof in concrete structure, causes the impediment in a long term and shortened the life span of durability. There are a lot of techniques for repair and reinforcement to improve using environment. However, the improper construction which is unconsidered various environmental conditions, could effect to increase the maintenance expenses. Therefore, this study will be compared and estimated the adhesion liquid and sheet integrate waterproofing material, as analyzing the existing problem. For those result, we would like to arrange the alterative plan for the long durability and user needs of concrete structure.

  • Due to a lack of objective and adequate study on the physical effects on hydroponic polyurethane waterproofing material water mixture ratio, construction site workers are having to rely on their hands-on experience to determine a mixture ratio, resulting in difficulty of maintaining quality management. Particularly in cases of rooftop exposed type hydroponic polyurethane materials, the varying temperature conditions make it further difficult for quality management control. in this regard, this study conducts tensile strength testing and compares the tensility change rates hydroponic polyurethane waterproofing materials with various water mixture ratios ranging from 0%~50% and exposed to alternating temperature change between -20℃ to 60℃ in the span of 1 hour after curing for 14 days.

  • 아스팔트계 교면용 방수재료는 방수재 상부에 고온의 아스콘이 타설되는 과정에서 재료가 연질화나 액상화되어 방수층의 불균형 및 두께감소 등이 문제점으로 남아있는 실정이며, 이를 해결하기 위하여 신규 재료의 개발과 도입 등 기존의 재료를 벗어난 해결방안이 요구되고 있다. 따라서 본 연구에서는 교면용 도막방수재의 기본물성을 만족한 MMA 도막방수재를 기준으로 전체 품질기준에 대한 물성을 파악하고 바탕 콘크리트, 방수재 및 포장층이 시스템화 된 상태에서의 품질기준 등을 확인하여 교면에 MMA 도막방수재로써 활용 가능 여부를 확인하였고, 그 결과 MMA 도막방수재는 경질 MMA 수지 : 연질 MMA 수지 : 파우더 = 6 : 34 : 60의 배합비를 통하여 안정적인 토목구조물 교면용 MMA 도막방수재의 적용이 가능할 것으로 판단되며, MMA 도막방수재와 아스콘간의 이질재료의 부착은 경화 특성을 가지는 유화 아스팔트를 활용하여 시공할 경우 국토교통부 '아스팔트 콘크리트 포장 시공 지침(2021.07)'의 최소 품질기준을 만족할 것으로 판단된다.

  • 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.

  • As the environment and energy problems such as global climate change (global warming, urban heat island phenomenon) and energy depletion have come to the fore, the construction and waterproofing industry are responding more critically to the demands of global green technology and are employing more eco-friendly technologies as of recent. In this study, the application of the waterproofing material with thermal response performance in construction buildings was investigated to confirm whether the thermal performance is being properly secured by the change of the surface temperature. Experimental results showed that the surface temperature difference between before and after the application is at least 19.8℃ at the maximum 26.3℃. When the degradation rate is converted, the degradation effect of about 40% on average was confirmed.

  • Waterproofing materials should be expected to last the life of the structure. An approximate life cycle cost should be to compare different materials based on initial and periodic repair / maintenance costs. Waterproofing applicators like materials that are easy to set up and clean up. The designer should choose a material that can be applied in almost all conditions. Design Professionals should specify independent inspection on critical jobs or in all cases where the budget permits. The basic causes of defection occurred during construction should be minimized.
