Abstract
An integrated waterproofing and air/vapor barrier membrane is provided which comprises a preformed waterproofing or sealing material layer (1) covered on one face with adherent impervious material (1), and on the other major face with an adherent porous support sheet (16). The waterproofing or sealing material layer can be covered on both sides with adherent support sheets. Heating of the barrier membrane allows self-adhesion to a surface on which it is applied after transudation of fusion of the sealing material through the support sheets.
