Claim 0:
1. A method for creating a secondary seal for a manhole assembly, said manhole assembly including a frame defining an access aperture therein and a cover received by said frame for covering said access aperture, said cover and said frame each having at least one circumferential surface, said method comprising:
providing a primary seal between said cover and said frame when said cover is received within said frame;
applying an amount of compound having a viscosity that allows it to flow to one of said circumferential surfaces of said cover or one of said circumferential surfaces of said frame to generate a circumferential deposition of said compound to form a secondary seal by said compound being compressed between said cover and said frame, wherein the compound is configured to provide a viscous barrier between said cover and said frame, to lubricate the engagement therebetween and thereby facilitate sliding or other movement of the cover relative to the frame, and to facilitate subsequent removal of the cover from the frame during use of the manhole.
