A sealing assembly for sealing the expansion gap between adjacent sectons of a structure has elongated elastomeric pads (2, 24) laid end to end along the length of the gap with a groove (6) in at least one of the end surfaces (4) of each pad for containing a flowable sealant (in Fig. 7 the abutting end surfaces of the pad are shown spaced apart for clarity). …<??>In order to achieve a seal which satisfactorily prevents access of debris and liquid into the expansion gap, while being easily formed after the pads are mounted in place, the groove has an inlet port at the top edge of the end surface through which the flowable sealant may be injected e.g. from a container (48). an intermediate sealing portion (12) for housing the sealant (46) to prevent debris and liquid from passing between the end faces, and a vent portion (22) communicating between the intermediate sealing portion (12) and the top edge of the end surface (4), so that sealant emerging from the top of the vent portion will indicate that the intermediate sealing portion has been filled. The other pad (24) may have a tongue which projects into, but does not fill, the groove (6), or may have a groove corresponding and opposed to the groove (6). The sealing portion (12) includes a length at the bottom edge of the endface (4), at which the sealant contacts the structure section. |
