SOPRAFIX® STICK is a flexible SBS elastomeric bitumen waterproofing membrane with a stabilized glass/polyester reinforcement.


The topside of SOPRAFIX® STICK is covered by a thermofusible film and the underside is covered with fine sand. SOPRAFIX® STICK includes a double overlap, self-adhesive overlap + torched or heat welded ensuring an easy and reliable installation. This first layer will be mechanically fixed.


  • High performance: composite glass/polyester reinforcement offers an excellent static and dynamic puncture resistance and high dimensional stability.
  • Versatility: designed to have a perfect adaptability to weather and movement of the substrate.
  • Reliability and durability: made from selected bitumen and polymers containing additives, which give a high resistance to weathering.
  • Mechanically fastened: as first layer in all two-ply self-protected elastomeric bitumen waterproofing systems.


SOPRAFIX® STICK must be laid semi-independently by unrolling the sheet on the substrate and mechanically fastened on the overlap. The self-adhesive part of the overlap must be laid and the second part must then be torch-on techniques or welded with hot air. This product requires a second layer of self protected elastomeric waterproofing.


  • Roll dimensions: 10 m x 1 m.
  • Roll weight: about 32 kg.
  • Storage: upright on pallet with plastic wrapping, protected against moisture
