Notes

  • Reinforcement guidance is general crack-control practice, not a stamped structural design — verify against local code, soil, and load.
  • Control joints ~every 10 ft; cut ~¼ the slab depth within 6–12 hours of the pour, and isolation joints at fixed structures.
  • Slope exterior flatwork ~¼″ per foot away from structures for drainage.
