    RAZISKAVA VZROKOV ZA DEGRADACIJO HIDROIZOLACIJE STREHE

    INDUSTRIJSKE HALE PAPIRNICE A-PRINT S PREDLAGANO SANACIJO

    Kljune besede: Ravne strehe, PVC-P membrane, poliuretanske kritine, parna zapora,

    toplotna izolacija, natezni preizkus

    Povzetek

    V diplomskem delu smo obravnavali ravno streho, kot najzahtevneji konstrukcijski element

    zgradbe, ki jo obravnavamo kot bazen. Ker je ravna streha podvrena izrazitemu toplotnemu

    delovanju, moramo upotevati poleg hidroizolacije tudi toplotno izolacijo.

    Pri izvedbi hidroizolacije pazimo na pravilno izbiro materialov, njihovo vgradnjo in skrbno

    izvedbo parne zapore. S stalia 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 lei v obmoju, kjer so pogosta neurja s too, zato smo za

    sanacijo strehe izbrali kritino EPDM-Resitrix MB, ki je odporna na too in ima dolgo

    ivljenjsko dobo.

    RESEARCHING THE CAUSES FOR THE DEGRADATION OF WATERPROOFING

    MATERIALS ON THE ROOF OF THE INDUSTRIAL HALL A-PRINT WITH THE

    SUGGESTED RESTORATION

    Key words: Flat roofs, PVC-P membranes, polyurethane roofing materials, vapour barrier,

    thermal insulation, tensile testing

    Abstract

    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 wasnt 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.
