Broom finish A texturing technique where a specialized stiff-bristled broom is dragged across freshly troweled concrete to create a slip-resistant surface.
A broom finish is a strict NYC DOT requirement for all public sidewalks. The fine ridges left by the broom bristles provide critical traction for pedestrians walking in rain, snow, or ice. A sidewalk finished with a smooth sheen without a broom finish will fail city inspections due to the high slip-and-fall risk it presents.
Frequently Asked Questions About Broom finish
What is a broom finish?
A texture created by dragging a stiff-bristled broom across freshly finished concrete, leaving fine ridges that provide traction.
Is a broom finish required in NYC?
Yes. A slip-resistant broom texture is the DOT requirement for public sidewalks.
Why does it matter for safety?
The ridges give pedestrians grip in rain, snow and ice, where a smooth surface would be hazardous.
Can a smooth sidewalk fail inspection?
Yes. Concrete finished with a smooth sheen and no broom texture can fail on slip-resistance grounds.
Which direction is the broom pulled?
Typically perpendicular to the direction of travel, so the ridges resist forward sliding.
