A method for waterproofing a substrate comprising steps of:
- i) attaching a separation sheet to a surface of the substrate and
- ii) attaching a waterproofing membrane sheet to a surface of the separation sheet by a plurality of adhesive elements having a first and second major adhesive surface, wherein
- the separation sheet is a non-woven fabric sheet or an embossed polyolefin membrane sheet and each adhesive element comprises an adhesive layer,
- the adhesive layer is composed of a pressure sensitive adhesive, and
- the adhesive layer of each adhesive element has a thickness of at least 300 μm.
A waterproofed structure comprising a substrate, a separation sheet attached to a surface of the substrate, and a waterproofing membrane sheet attached to a surface of the separation sheet via a plurality of adhesive elements having a first and second major adhesive surface, wherein the separation sheet is a non-woven fabric sheet or an embossed polyolefin membrane sheet and each adhesive element comprises an adhesive layer, the adhesive layer is composed of a pressure sensitive adhesive, and the adhesive layer of each adhesive element has a thickness of at least 300 μm.
