A self-adhesive water proofing product which comprises:
- (a) a water proofing layer, and
- (b) an adhesive layer comprising a mixture of from about 85% to about 99.5% of a bituminous component and from about 0.5% to about 15% of a block copolymer comprised of at least one vinyl aromatic hydrocarbon and at least one conjugated diene wherein the block copolymer contains at least 0.2% of at least one functional group selected from the group consisting of carboxylic and acid or anhydride groups or derivatives thereof including salts, esters, imides, amides and acid chlorides.
