23 A study in the Water Leakage Prevention around the Windows with the Stone Materials in the Apartment House Abstract This study intends to suggest the effective methods for water Leakage prevention around the windows in stone works toupgrade the outdoor public space that has been taken much portion of apartment housing trends. The subjects of the study was selected among the domestic subcontractors of stoneworks. There are four methods for waterleakage prevention around the windows; Firstly, the painting water-proof method after the masonry. Secondly, the urethane water-proof method after galvanizing panels on the gap. Thirdly, the separation method between stone and substructure and the last one is water-proof metod that they put some water-proof screen between stone and substructure with the EPDM sheets. Acoording to the analysis of the water-proof effects, constructability and planning, we could approach to conclustion that the most influent items to the water-leakage are the filling material s deformation, the state of oxygenation and deterioration of work skill. Among the water-proof methods in construction the EPDMsheet is most excellent water-proof method to meet the technicalconditions. However, we have to apply it to stone works as a water-proof method for the decrease of the leakage defects after standardizing the materials, test and construction skill because there are many work skills according the subcontractors.

26 Investigation of the Stone Contamination Degree by Sealants on the Joint of Building Stone Wo r k Abstract This study is to investigate the stone contamination degree by sealants on the joint of building stone work among other contaminations occurring in the stone building and to devise a countermeasur ifr reducing stone-contamination. For this purpose, after producing experimental specimens, tests were performed to anayze the stone contamivation degree by sealants according to the kinds of granite and sealants and surface treatment of the joint. As a result of this study, the contamination shows wide differences depending on the kinds of granite, sealants, and surface treatment of the joint. Especially, it is the most effective to apply fitting primer on the joint-surface of the stone in terms of preventing plastic ingredients, which are the main cause of contamination, from being absorbed into the stone structure.
