10 x 10 Concrete Slab Cost in Construction – Complete Guide
A 10 x 10 concrete slab is a common project in construction, often used as a foundation for sheds, patios, small garages, or outdoor seating areas. Measuring 100 square feet, this slab is a manageable size for both DIY enthusiasts and professional contractors.
However, the cost to build a 10 x 10 concrete slab depends on multiple factors—material prices, labor rates, site preparation, reinforcement, and finishing details. In this guide, we’ll break down average prices, cost variables, installation steps, and tips to save money while ensuring a durable slab.
Average Cost of a 10 x 10 Concrete Slab
The price to install a 10 x 10 concrete slab typically ranges between $600 and $1,200, depending on quality, thickness, and location.
| Slab Type | Thickness | Cost per sq. ft. | Total Estimated Cost |
|---|---|---|---|
| Basic Slab | 4 inches | $6 – $8 | $600 – $800 |
| Reinforced Slab | 4–6 inches | $8 – $10 | $800 – $1,000 |

Factors Affecting 10 x 10 Concrete Slab Cost
Several variables influence the final price:
1. Slab Thickness
- 4 inches – Standard for patios and walkways.
- 6 inches – Recommended for heavy loads, like driveways or equipment pads.
2. Reinforcement
- Wire mesh or rebar adds strength and prevents cracking but increases cost.
3. Site Preparation
- Clearing vegetation, grading, and adding a gravel base add to labor and material costs.
4. Concrete Quality
- Higher PSI concrete (3,500–5,000) costs more but provides better durability.
5. Finishing
- Smooth, broom, or decorative stamped finishes have different price ranges.

Step-by-Step Installation of a 10 x 10 Concrete Slab
Step 1: Planning & Measuring
- Mark the slab location with stakes and string.
- Decide on thickness and reinforcement needs.
Step 2: Site Preparation
- Excavate the area to the required depth.
- Add and compact a gravel base for drainage.
Step 3: Formwork Setup
- Install wooden or metal forms to contain the concrete.
- Ensure forms are level and square.
Step 4: Reinforcement Placement
- Place wire mesh or rebar inside the form to increase strength.
Step 5: Concrete Pouring
- Order ready-mix concrete or mix on-site.
- Pour evenly across the formwork.
Step 6: Leveling & Smoothing
- Use a screed board to level the surface.
- Smooth with a float or apply a broom finish for traction.
Step 7: Curing & Sealing
- Allow concrete to cure for at least 7 days before heavy use.
- Apply a sealer for added durability (optional).
Tips to Save Money on a 10 x 10 Concrete Slab
- DIY Labor – Handle excavation and form setup yourself.
- Order Correct Amount of Concrete – Avoid over-ordering to prevent waste.
- Use Standard Finish – Decorative finishes increase cost.
- Build in Off-Season – Contractors may offer discounts during slower months.
