The compound is the main constituent of the membrane. It gives the waterproofing properties and during the production is used to cover the reinforcement to obtain the final product. The main constituents of the compound are: bitumen - polymers - filler. The compound is prepared in the Mixers which are agitated vessels where the dissolution process of the polymers into the bitumen and the dispersion of the filler takes place. From these mixers the compound is trasnferred to other storage mixers, and finally to the production line, where it is used to impregnate the reinforcement to produce the membrane.

MEMBRANE:to better understand the membrane types, we consider the upper and lower surface during the production and not laden on a roof. For example, producing slate membrane the granules are on the top both on roof than in production; producing black membrane, film is on the upper side and sand on the lower, opposite on a roof.

Upper Surface Finishing:

  • Smooth PE or TNT
  • Embossed PE or TNT
  • Sand
  • Granules or slate

Lower Surface Finishing:

  • Smooth PE
  • Wet talc
  • Sand
