Bowers Basebed

Portland Stone Bowers Basebed



The Jordans Mine extraction faces are now moving under the road much closer to the Bowers Quarry site.  We are predictably noticing that the geological characteristics of these stones are becoming very similar.  We have therefore changed the Basebed Panels to have a single panel representing both stones as the differences are undetectable in a factory manufacturing environment.

Shell Content

Clean Basebed, it may contain small grey shell fragments. Some recent production has higher concentration of shells.

Shell Distribution

The shell fragments are randomly distributed across the stone. Some areas in the quarry have yielded cross bedding.


Bowers Basebed has a tight texture but some of the recent production is a little coarser than previously extracted.


Typical Portland colour, creamy/white. The shell concentrations and texture variation can give it slightly deeper tones.
