The PENTAFLEX® OBS pre-break elements are part of the PENTAFLEX® joint sealing system designed for the construction of water-impermeable concrete structures (white tank) and are used for creating target ruptures in in-situ concrete walls. They comprise a seam sheet with the tried-and-tested PENTAFLEX® special coating as well as galvanised steel sheet wings which weaken the concrete cross-section. The joint formed is simultaneously secured against pressing water by the integrated sealing element.
