A stackable polymeric foam adjustment or grade ring is provided for the construction of the adjustment courses or manhole chimney portion of a sewer system. The adjustment ring is circular and may include concentric annular grooves on at least one surface and male portions corresponding in size and shape to the concentric annular grooves on a second surface. The adjustment rings are stacked one on another with the respective male portions being coupled within a corresponding annular groove to provide a manhole construction that is resistant to inflow, ch...


What is claimed is: 1. In a manhole assembly having a longitudinally upper frame portion disposed on a longitudinally lower cone portion, an improved structure for substantially preventing inflow of water or other material between the upper frame portion and the lower cone portion, the improvement comprising: a plurality of continuous and compressible polymeric foam construction grade rings serially stacked longitudinally and laterally aligned with one another between the upper frame portion and the lower cone portion, one of said grade rings being seal...
