The average cost of having concrete flatwork installed typically starts at $6 per square foot and can go up to $15 or more per sq. ft. for a complex design.
To break it down, the concrete cost depends on the following needs and requests:
1. size and thickness (4" thick is the norm)
2. desired shape
3. amount of reinforcement
4. spacing of control joints
5. special effects such as stain, integral color, decorative aggregate, surface designs, or borders
6. grade or slope of your yard
7. whether steps are required
