Anderson, about this asphalt layer.

i understand what you are getting at, but could you please link to a specific product web page for something you would recommend that is available here in europe?

im not quite sure whether you mean an asphalt-type adhesive or a membrane type thing on a roll.

if it is a membrane on a roll as such, how do you secure the sandwich tightly without puncturing the membrane? how do you sandwich it so tightly that it will not sag and decouple over time?

thanks,
