1. A sealing device comprising:
i. a waterproofing membrane having a first primary exterior surface and a second primary exterior surface and a width defined between opposite longitudinally extending edges,
ii. a sealant layer covering a portion of the second primary exterior surface of the waterproofing membrane and coated directly onto the second primary exterior surface of the waterproofing membrane, and
iii. an adhesive layer covering a portion of the second primary exterior surface of the waterproofing membrane and coated directly onto the second primary exterior surface of the waterproofing membrane,
wherein the sealant layer and the adhesive layer are configured to directly adhere to a substrate to be waterproofed, and
wherein the sealant layer comprises an adhesive sealant composition comprising:
a) 1-40 wt.-% of at least one elastomer,
b) 10-60 wt.-% of at least one polyolefin resin that is liquid at 25° C., and
c) 5-65 wt.-% of at least one inert mineral filler, all proportions being based on the total weight of the adhesive sealant composition.
