A comparatively wide, extruded elastomeric sealing strip, for sealing expansion grooves in bridges or the like, having a wall construction including a transversely oriented internal wall to resist lateral compression thereof and a criss-crossed arrangement of walls supporting the transverse wall from below, such wall construction having the unique feature of a sufficient number of internal walls as to obviate a length in any one such wall that might collapse under its own weight prior to completion of the curing of the elastomeric, and yet not having that great a number of walls as to complicate the fabrication of the device by extrusion.
