ABSTRACT:
An internal seal is disclosed between a manhole casting and mating manhole components such as concrete adjusting rings, the concrete manhole cone, or masonry structure of a similar configuration, to prevent water infiltration at this interface. The seal is formed by a continuous elastomeric ring. The ring is held in place by two stainless steel retaining bands. The elastomeric ring is pleated to allow an upward movement or lateral movement of the casting without impairing the sealing ability of the ring. The gasket can be installed either during construction or at any time after construction that there is found to be a problem with infiltration.
