Sealing strip for waterproofing plastics-lined building elements - has Y-cross=section with one flange inserted into gap to be sealed

摘要

Plastics e.g., plasticised PVC, strip for sealing the gap between abutting plastics - lined building components, esp. concrete components, e.g. prefabricated drainage or sewerage pipes, has a vaguely "Y"-cross-section. This profiling efficiently and simply seals the abutting ends of the building components and the intervening gap.
