A method for installing a gasket having a first exposed pipe-engaging portion and a second portion which is anchored within a peripheral wall of an opening in a poured-in-place concrete wall. The method includes the first step of erecting a form including an inner wall and an outer wall to define the poured-in-place concrete wall, the outer wall of the form having an opening in the region where the opening in the poured-in-place concrete wall is to be. The second step includes providing an assembly of an inner mold disc having a central particularly defined shape, the gasket, having a particularly defined shape and disposed in a particularly defined orientation, and an outer mold disc having a particularly defined shape. The third step includes suspending the assembly at a desired predetermined location between the inner and outer walls by a depending fixing bar, having a particularly defined shape; the suspending being by a particularly defined bolt structure. A further step includes in-filling the space between the inner and outer walls of the form with settable concrete material, so as to anchor the gasket in the settable concrete material. The final step includes after setting of the settable concrete material, removing the form and the inner and outer mold discs, so as to leave the first, exposed pipe-engaging portion of the gasket which is not embedded in the set concrete material projecting into the opening intended to receive the pipe.
