Finish Descriptions

There are a variety of basic finish options available which may be applied to the top and face of a vertical curb. Any combination of these finish treatments may be specified, i.e., sawn top, split face; thermal top, split face, etc.

  • Sawn top: most common; slabs for curb are typically sawn top and bottom; the top of the curb has a smooth finish created by saw cutting.
  • Split top: for an historic look.
  • Thermal top: fine stipple finish for aesthetic look or traction in pedestrian areas.  Slab is processed through a thermaling machine, then split or sawn into curb.
  • Sawn face: the face of the curb has a smooth finish created by saw cutting.
  • Split face: a natural face created when the slab is split on a guillotine; the resulting face of the curb has a rough finish.
  • Clean back: protrusions greater than 1/4-inch are removed using hand tools to create a tighter tolerance for when pavers are abutted to curb.
  • Sawn back: provides the tightest tolerance for when pavers are abutted to curb.
  • Rock Face: hand chiseled to create a relief finish.
