Designing flat roofs has many issues and decisions. This can be, for example, the decision on how to close the flat roof. By default, roofs are terminated at the periphery by means of attics or by creating a so-called rigid edge of the roof. This paper focuses on the first option, and therefore the termination of the flat roof using the atics. The author is dealing with the findings with regard to the way the proposal is implemented and the subsequent realization of the details. As a major waterproofing layer, fil...

The post-mining excavation "Piaseczno" is located in the south-eastern part of Poland, on the left bank of the Vistula River.
