A sealing member having an elongate body formed of an elastomeric material has a generally planar sealing surface adapted to provide an outward sealing force in a direction generally perpendicular to the sealing surface. The seal further includes a plurality of longitudinally extending hollow regions formed within the sealing member which are bounded at least in part by longitudinally extending and transversely spaced apart structural partitions. A layer of elastomeric material on a side opposite the sealing surface spans the structural partitions thus enclosing the hollow regions. The seals are useful in constructing segmented tunnels, ducts, and the like, and are particularly adapted to withstand high pressures.
