  The foundations, roof, walls, protection, sound insulation and most importantly waterproofing of the construction is quite important[1]. For this purpose, various materials are produced nowadays. In this study, membrane materials with waterproofing properties were produced using polypropylene with bitumen, mineral oil (waste oil), filler (calcite). Similar materials were also produced using styrene-butadiene-styrene copolymers. The properties of these two membranes, such as softening, temperature resistance, fracture temperature and tensile strength, have been investigated.
  The produced membrane material made of polypropylene was melted completely and totally absorbed into polyester felt. The softening point, temperature resistance, fracture temperature, tensile strength (width / length) and elongation at break (width / length) of this material were found to be 140 °C,    120 °C,  -94 °C,  600/800 N/5cm  and 35/35 %, respectively and also styren-butadien-strien (SBS) copolymer membrane's the softening point increased to 147, temperature resistance is constant,  fracture point decreased to 9.8 and tensile strength and tensile elongation is constant[2,3].
