Beschreibung
Zusammenfassung:	Disclosed are waterproofing membranes comprising the following laminated layers: layer A comprising a waterproofing adhesive; layer B comprising a carrier sheet; layer C comprising a releasable bonding material; and layer D comprising a protective coating; wherein (i) the laminated layers are arranged in the sequential order A-B-C-D; or (ii) the laminated layers are arranged in the sequential order B-C-D-A; or (iii) the laminated layers are arranged in the sequential order C-D-A-B. The membrane does not include a removable release sheet that is typically used to prevent the adhesive from adhering to the carrier sheet or other portion of the membrane when the membrane is rolled up. Also disclosed is a method of making the aforementioned membrane. Preferably, layer C will comprise a water soluble polymer, an alkali soluble polymer, or a homopolymer or copolymer of polyvinyl acetate.
