BTM Polibit

BTM Polibit is a fiberglass or polyester felt reinforced waterproofing membrane made of bitumen modified with APP (atactic polypropylene), the lower surface is coated with PE (polyethylene) film and the upper surface is coated with PE (polyethylene) film or colored granules and applied with an oxyacetylene burner. We, BTM, may produce 10 types of the Plastobit membrane with different properties.


Superior performance in hot and moderately cold climates


Used to obtain water and moisture impermeability on:

  • terrace roofs of buildings,
  • sloping concrete roofs,
  • curtain walls, foundations.
  • Polibit is designed for moderate climates and used as lower and middle layer membrane in waterproofing.
  • It is used in the insulation of pressurized and non-pressurized underground or surface waters.


Surface on which application shall be carried out must be cleaned of any dust, dirt, rust and grease and any loose parts scraped. BITUSOL or BITUMER undercoat must be apllied to the surface and allowed to dry up depending on the surface where necessary.


If the surface to be insulated is concrete, then it must have been finished with sloping grout burnished using a wooden trowel and be clean and dry. Before the application of the membrane, the surface must have been spread with bituminous solution undercoat BITUSOL (TS 103) or bituminous emulsion undercoat BITUMER (TS 113) and allowed to dry up. Depending on the slope of the ground, BTM Waterproofing Membrane Polibit application starts from low to high elevations. BTM Polibit is adhered to the surface by heating it with a torch flame. There must be staggering between rows. A 15 cm overlap should be left for the short side overlaps of 1 meter, and at least 10 cm should be left for the long side overlaps, and a roller should be used for gluing the joints. Between the floors, there should be a 50 cm staggering on the short side and 5 m on the long side.


Polibit, is launched into the market in rolls 1m wide and 10m long.


The membrane rolls should be stored vertically under a roof, protected from direct sunlight. If the rolls have to be stored outdoors for a long period of time, they must be covered with a protective layer in order to protect them from the sunlight. The membrane rolls or pallets should not be stacked on each other.
