|---|---|---|
| 20×20 slab | 400 | about $3,600 |
| 20×30 slab | 600 | about $5,400 |

What changes the price
- Slope: our prices are for level ground. A sloped lot needs extra grading, fill, forming or steps, so it is priced after we see the site.
- Removing old concrete: removal and haul-off adds $4–$8 per sq ft.
- Thickness and steel: thicker slabs, rebar and heavier loads (RVs, shops) cost more.
- Site prep: fill and drainage on soft or low ground.
- Finish: stamped, colored or decorative finishes cost more than broom finish.
- Access: tight backyards where a truck cannot reach may need a pump or wheelbarrows.
- Foundations: a house foundation needs engineered plans, and post-tension or pier foundations cost more than a basic slab-on-grade.
