Pigmented Concrete (Historic Materials)

Usage: Historic

Same mixture as Unpigmented Concrete, but with an added pigment to simulate granite slabs or bluestone flags in historic districts, as per LPC guidelines, or in historic, non-landmarked neighborhoods, as per PDC guidelines. This is one of two kinds of pigmented concrete — see also Pigmented Concrete (Dark).

Concrete pigmented to simulate granite: 9th Avenue, Manhattan
Concrete pigmented to simulate granite


See benefits of Unpigmented Concrete

  • Reinforces historic character
  • Saw-cut joints provide cleaner look, simulating individually hewn blocks of stone, and add to the historic character of this treatment
  • Less costly than bluestone flags or granite slabs


See considerations of Unpigmented Concrete

  • Different in appearance from new granite or bluestone


  • Appropriate, pending LPC review, in historic districts where LPC sidewalk regulations remain in force as a replacement for granite or bluestone that is beyond repair
  • Appropriate, pending PDC review, in historic, nonlandmarked neighborhoods as a replacement for granite or bluestone that is beyond repair

See design guidance for Unpigmented Concrete

  • Flag size and pigmenting to match existing granite slabs or bluestone flags per LPC or PDC guidelines
  • Sustainability opportunity: Supplementary cementitious materials (SCM)
  • Sustainability opportunity: Recycled concrete aggregate (RCA)


See maintenance for Unpigmented Concrete

  • Adjacent property owners are generally responsible for maintaining this material
  • All sidewalk repair or replacement in historic districts requires written approval from LPC
