AUTOTAK  is a self-adhering waterproofing membrane made of distilled bitumen modified with SBS (styrene-butadiene-styrene) polymers, with an adhesive coating on the lower face. Application is very simple and safe: once aligned the roll in place over a clean and primed substrate, by simply removing the silicone films from the underside and from the selvedge strips, AUTOTAK will adhere in place without the need of a propane gas torch or a hot air machine.



The carrier is a composite polyester stabilised with longitudinal glass yarns that combine superior dimensional stability with high tensile strength and elongation values and excellent mechanical properties in general. 


Intended use according CE Mark Standards

  • AUTOTAK   3,0 mm - 4,0 mm: underlay or intermediate layer in multi-layer systems for roof waterproofing (EN 13707);
  • AUTOTAK  MINERAL  3,5 kg/m² -  4,0 kg/m²: waterproofing under slates or tiles (EN 13859-1). 



Available surface finishes


AUTOTAK - upper surface

TEX PE film with 10 cm silicone release side overlap.
Standard Standard


AUTOTAK MINERAL - upper surface

Self-protection by means of slate flakes available in standard grey or other various colours upon request: protects the membrane from ageing caused by UV rays.


Lower surface

Lower face is covered with a silicone release film, non-stick and removable, divided into two parts for easy placement and alignment of the rolls during the application.



Use & Application

Flat roofs  Pitched roofs Vaulted roofs Industrial roofs

AUTOTAK and AUTOTAK MINERAL are indicated, respectively, as underlay or as waterproofing layer below roof tiles or on pitched roofs in general where the use of a free flame is not permitted or advisable, thus preventing the use of a torch applied membrane (for example: over wooden decks or fire sensitive insulation layers). 

For correct installation refer to information provided by Copernit Technical Department.
