This group of natural stone distinguishes itself by:
  • A natural cleft, rough surface with slate and quartzite.
  • A higher water absorption and lower resistance to abrasion with sandstone, cantera, Indiana Limestone. Both the natural cleft surface and higher absorption make these materials especially prone to staining (even during installation), dirt retention, and wear.
