A Study on complex waterproofing Method Using Part of Joint Watertightness Improved Sheet

접합부 수밀성 향상 시트를 이용한 복합방수 공법에 관한 연구

We ensure a flat and regular basic surface by using part of joint waterproofing improved sheet method applying the upper slab of a concrete structure. We solve the problem of getting loose scale the general sheet by waterproofing of the sheet and improving adhesive strength of the basic concrete. Also, waterproofing sheet union to problem of joint have solved using of insertion type method so that, it improved a watertightness. It has improved in resist impact, resist abrasion and it is the effect of shortened construction period and cutting down on construction expenses. Here are the special quality and superiority of this waterproofing research. (1) Level material has the super adhesive strength so that it makes the basic surface without the gab of waterproofing sheet and waterproofing layer with the string adhesive strength. (2) We unite the sheet with the joining part between sheets by waterproofing sheet joint using of method. (3) There is the effect of shortened construction period and cutting down on construction expenses without waterproofing of protection.
