Claims17
A sealing device in the form of a tape comprising a waterproofing layer having first and second major surfaces and comprising at least one thermoplastic polymer P1 and a functional layer having first and second major surfaces and comprising:
- a) 10-70 wt.-% of at least one thermoplastic polymer P2 and
- b) 30-90 wt.-% of at least one solid particulate filler F, the proportions being based on the total weight of the functional layer, wherein
- the functional layer and the waterproofing layer are directly connected over at least part of their opposing major surfaces and wherein the sealing device further comprises an adhesive layer coated on and at least partially covering the first major surface of the waterproofing layer opposite to side of the functional layer.
