RESEARCHING THE CAUSES FOR THE DEGRADATION OF WATERPROOFING MATERIALS ON THE ROOF OF THE INDUSTRIAL HALL A-PRINT WITH THE SUGGESTED RESTORATION

V diplomskem delu smo obravnavali ravno streho, kot najzahtevnejši konstrukcijski element zgradbe, ki jo obravnavamo kot bazen. Ker je ravna streha podvržena izrazitemu toplotnemu delovanju, moramo upoštevati poleg hidroizolacije tudi toplotno izolacijo. Pri izvedbi hidroizolacije pazimo na pravilno izbiro materialov, njihovo vgradnjo in skrbno izvedbo parne zapore. S stališča gradbene fizike delimo ravne strehe v osnovi na tople in hladne strehe. V delu je predstavljena topla ravna streha iz PVC-P hidroizolacije preplastena s poliuretansko hidroizolacijo. Preiskava je pokazala, da sanacija strehe s PVC-P membrano ni bila ustrezno izbrana.. Objekt leži v območju, kjer so pogosta neurja s točo, zato smo za sanacijo strehe izbrali kritino EPDM-Resitrix MB, ki je odporna na točo in ima dolgo življenjsko dobo.In this diploma thesis we researched the flat roof, as the most advanced construction element of a building. We regard it similar to a pool. Because this flat roof was subject to extreme heat exposure, we have to research the thermal insulation as well as the waterproofing materials. When waterproofing a roof, we have to be cautious about choosing the right materials, building them in and the right placement of a vapour barrier. Building engineering physics separate two kinds of flat roofs, the cold and the warm roof. The flat roof presented in this diploma thesis is a warm roof, consisting of PVC-P waterproofing membranes, covered with a layer of polyurethane liquid waterproofing material. The research showed that the restoration of the roof with the PVC-P membrane wasn’t adequately chosen. The building is located in a place, where hailstorms are not an uncommon phenomenon, that is why we have chosen to restore the roof with the membrane EPDM – Resitrix MB, that is resistant to hail and has a long lifespan
