ABSTRACT
ABSTRACT: Presently we often come across with dysfunctional leaking flat roofs, where the Damp Proof Course (aka DPC) is of poor quality or was damaged. Until recently, the most widely used material for damp-proofing of flat roofs-bitumen, is being replaced with plastic-based membranes. These plastic membranes, especially mPVC-based, are used not only for new buildings, but also for reconstruction and restoration of old roof structures. The use of these membranes comes both with advantages as well as with problems that occur during their installation. The technology of roof construction using this type of membrane is essential for their quality. Therefore, the aim of this paper is to explain basic attributes of mPVC-based waterproofing membrane´s joints and how the technology of construction affects them.
