The joint seal has a stretchy, corrugated zone (3) formed between two flat strips (1,2). The corrugated zone may have folds, wave formations or a similar profile, and run along the longitudinal axis. The zone may alternatively be formed in an OMEGA shape to form a loop. The sealing band may be formed of a textile or non-woven webbing or of a uniform density material, such as plastics or rubber, and may have a waterproof coating or an impregnation. |
