ABSTRACT:
An improved sealing assembly for sealing the expansion gap between adjacent sections of a structure has elongated elastomeric pads laid end to end along the length of the gap with a groove in at least one of the end surfaces of each pad for containing a flowable sealant.
The groove has an inlet port at the top edge of the end surface through which the flowable sealant may be injected, an intermediate sealing portion for housing the sealant to prevent debris and liquid from passing between the end faces, and a vent portion communicating between the intermediate sealing portion and the top edge of the end surface, so that sealant emerging from the top of the vent portion will indicate that the intermediate sealing portion has been filled.
