Above is the range panel located at our factory on Portland which shows the typical geological characteristics of Bowers Roach

Shell Content

Shelly Roach contains large grey shell fragments. The shells include Turreted Gastropods (Portland Screws) as well as large clam shells.

The Roach on this panel is face bedded.

Shell Distribution

The shelliest sections of Roach tend to be towards the middle of the blocks.


The large Turreted Gastropods and clam shells are associated with voids. Some of the voids can be in excess of 50mm long and the stone's texture in between the voids is often tight and dense.


Typical Portland colour - creamy/white, although the large concentrations of grey shells can darken the overall colour.
