SBS-modified bitumen self-adhesive non-reinforced membrane for waterproofing without torching

Self-adhesive carrier less SBS-modified bitumen membrane ULTRAFLEX SA NB is designed for waterproofing of foundations and engineering structures, indoor waterproofing. Thanks to the special adhesive bitumen compound, the material can be used on surfaces, where the standard torch-on application is forbidden (expanded / extruded polystyrene or wooden base).

ULTRAFLEX SA NB waterproofing material is produced by placing a special self-adhesive polymer-bitumen binder on a thick polymer film that covers the material on top. The other side of the material is covered with a removable protective film. The absence of a carrier is a key feature of this material that makes it very elastic and flexible. 

Waterproofing material ULTRAFLEX SA NB has the following advantages:

  • Can be used on surfaces, where the standard torch-on application is forbidden (wood, XPS, etc.);
  • High speed of application;
  • No need for any additional equipment and skills;
  • Safe and cheap application – the membrane is applied without the use of gas and flame;
  • Can be used for indoor waterproofing in a closed area.
