"Saturated void" is a geotechnical term, but Tim Flohr Sørensen uses it to describe a cemetery:

It may appear rather straightforward to connect cemeteries with the notion of absence.  After all, a cemetery is most often seen as a place for the dead, who are frequently conceived as absent, gone, missing or lost.  The state of being — or non-being — of the dead is otherwise poorly defined, and may simply be considered a form of "no moreness."  At the same time, the cemetery can be said to contain the absent, because it is ordinarily a place where prolonged spatial and material relations to the deceased are allowed to exist as opposed to e.g. a mass grave, where the dead are meant to disappear. ... [Cemeteries are] places of highly complex incorporations of presences and absences.  ...  [A]bsence is articulated and perceived as an emotional rupture but also as concrete and material voids.  Likewise, presence is articulated both as the physical being-there and the feeling of nearness and immediacy in the midst of the fragmentation posed by the death of a relative.  ("A Saturated Void: Anticipating and Preparing Presence in Contemporary Danish Cemetery Culture," An Anthropology of Absence)
