SOPRAROCK APP P3 is used as an underlayer in a multi-layer system and can be torched-on.


Due to its composition SOPRAROCK APP 3 has a perfect dimensional stability. The homogeneity between the surface density and the impregnation mixture gives the membrane a very high resistance to delamination. Waterproofing membrane composed by APP modified bitumen with a nonwoven polyester reinforcement. The upper side is finished with sand/talcum. A torch-on film protects the lower side.  


SOPRAROCK APP P3 can be fixed mechanically to the substrate as a first layer.
