What is a Poured Concrete Wall?

A poured concrete wall is a vertical concrete structure formed by placing wet concrete into pre-built forms (usually made of wood or metal) and allowing it to cure. These walls are commonly used for:

• Foundations for residential and commercial buildings
• Basement walls
• Retaining walls for landscaping
• Structural walls in industrial facilities

Unlike concrete blocks or precast panels, poured concrete walls are formed on-site, creating seamless, solid walls with high structural strength and water resistance.

Why Use a Poured Concrete Wall Cost Calculator?

Several variables affect the cost of constructing a poured concrete wall: wall height, length, thickness, type of concrete, rebar reinforcement, labor, excavation, and formwork. A Poured Concrete Wall Cost Calculator helps you:

• Estimate the total cost based on wall volume and specifications
• Compare pricing across different wall sizes and reinforcement needs
• Budget for large- or small-scale projects
• Prepare for contractor bids and project timelines
• Avoid underestimation and unexpected expenses

Whether you’re building a full basement or a short retaining wall, this calculator gives clarity and confidence during planning.

Average Cost of a Poured Concrete Wall

The national average for poured concrete wall construction ranges from $90 to $250 per linear foot, depending on thickness, reinforcement, and labor.

These prices typically include excavation, rebar, concrete, formwork, and labor.

Poured Concrete Wall Cost Formula

Use this basic formula to estimate your wall cost:

$$[
\text{Total Cost} = \text{Wall Volume (cu ft)} \times \text{Cost per Cubic Foot}
]$$

To find wall volume:
$$[
\text{Volume} = \text{Length} \times \text{Height} \times \text{Thickness (in feet)}
]$$

Example:
An 8-ft high, 30-ft long, and 0.5-ft thick wall:
30 × 8 × 0.5 = 120 cubic feet
If cost is $10 per cubic foot:
120 × 10 = $1,200

This provides a quick, approximate estimate. Use the calculator to adjust thickness, formwork, and reinforcement.

Key Cost Components

1. Wall Dimensions

Wall size has the biggest impact on cost. Key measurements include:

• Length: Total wall run (usually in feet)
• Height: Commonly ranges from 4 to 10 feet
• Thickness: Standard walls are 6 to 12 inches thick

Thicker walls cost more due to increased concrete and rebar needs.

2. Type of Concrete

• Standard mix (3,000 PSI): $135 – $160 per cubic yard
• High-strength mix (4,000–5,000 PSI): $160 – $200+ per yard
• Waterproof concrete: Often used for basements or retaining walls

Concrete is typically delivered by truck. Most mixes cover about 81 cubic feet per cubic yard.

3. Reinforcement (Rebar and Mesh)

Steel rebar is critical for structural integrity and crack resistance.

• #4 rebar: $0.70 – $1.00/linear foot
• Rebar installation labor: $0.50 – $1.50/foot
• Wire mesh: $0.20 – $0.40/sq ft

More reinforcement is needed for load-bearing or retaining walls.

4. Formwork

Formwork holds the concrete while it cures.

• Wood forms: Temporary and affordable
• Metal or panel forms: More durable and reusable
• Cost: $2 – $6/sq ft, including setup and removal

Complex shapes or taller walls increase formwork cost and time.

5. Labor Costs

Labor typically includes:

• Excavation and grading
• Form construction and placement
• Concrete pouring and finishing
• Form removal and site cleanup

Labor costs vary by region and difficulty, averaging $50 to $100/hour per worker.

6. Excavation and Backfilling

Excavation is required for below-grade or retaining walls.

• Light excavation: $2 – $4/sq ft
• Deep excavation: $4 – $10/sq ft
• Backfilling with gravel or soil: $1 – $3/sq ft

Soil type and access affect the price significantly.

Example Cost Scenarios

Example 1: Small Retaining Wall (4-ft high, 20-ft long)

• Thickness: 8 inches (0.67 ft)
• Volume = 20 × 4 × 0.67 = 53.6 cu ft
• Concrete cost: $10/cu ft
• Total: 53.6 × 10 = $536 (materials only)
• Add $1,000 for labor and formwork
• Estimated total: $1,500

Example 2: Basement Wall (8-ft high, 40-ft long)

• Thickness: 10 inches (0.83 ft)
• Volume = 40 × 8 × 0.83 = 265 cu ft
• Concrete cost: $9.50/cu ft
• Total: $2,517.50
• Add $2,000 for rebar, labor, excavation
• Estimated total: $4,500–$5,000

Example 3: High Structural Wall (10-ft high, 50-ft long)

• Thickness: 12 inches (1 ft)
• Volume = 50 × 10 × 1 = 500 cu ft
• Concrete cost: $11/cu ft
• Total: $5,500
• Add $3,500 for reinforcement, formwork, equipment
• Estimated total: $9,000

When to Use a Poured Concrete Wall Cost Calculator

Use this calculator when:

• Building a new basement or foundation wall
• Planning a retaining wall for landscaping
• Replacing a failing stone or block wall
• Estimating costs for commercial or agricultural buildings
• Preparing permit applications or loan documentation

The calculator helps you adjust variables and get fast, reliable budget estimates.

DIY vs Professional Installation

DIY is best for small, above-grade projects. Structural walls, deep foundations, and retaining walls should be handled by professionals.

Additional Costs to Consider

• Pump truck rental: $500 – $1,000/day
• Waterproofing membrane: $1 – $3/sq ft
• Drainage tile: $1.50 – $3/linear foot
• Gravel backfill: $30 – $70/ton
• Permit and inspection fees: $100 – $500
• Concrete curing/sealing: $0.25 – $1.00/sq ft

Including these extras in your estimate gives a realistic total project budget.

How to Measure for Your Wall

1. Measure the length of the wall (in feet)
2. Measure the height from base to top
3. Choose your thickness (6″, 8″, 10″, or 12″)
4. Convert thickness to feet (e.g., 8″ = 0.67 ft)
5. Calculate volume = length × height × thickness

Use these figures in the calculator to estimate concrete, rebar, and labor requirements.

Tips to Save on Poured Wall Costs

• Choose standard concrete mix unless high strength is needed
• Use modular forms or rent reusable systems
• Combine multiple walls into one pour to reduce setup costs
• Keep walls under 8 ft if possible to avoid extra formwork bracing
• Plan site access for easy equipment delivery
• Get at least three contractor quotes for comparison

Proper planning reduces overruns and improves build efficiency.

Frequently Asked Questions

Are poured concrete walls better than concrete blocks?

Yes. Poured walls are stronger, more waterproof, and more seamless than block walls. They resist lateral pressure better and are less prone to joint leaks or settling.

How thick should a poured concrete wall be?

• Basement walls: 8–10 inches
• Retaining walls: 8–12 inches
• Structural/commercial walls: Up to 16 inches or more
  Thickness depends on height, load, and soil conditions.

Do poured concrete walls need waterproofing?

Yes. For below-grade walls (like basements), apply waterproof membranes and install proper drainage systems to prevent moisture infiltration.

How long does a poured wall take to cure?

Concrete typically sets in 24–48 hours but takes 7 days to partially cure and 28 days to fully cure. Forms are usually removed after 48 hours if conditions are ideal.

Can I pour concrete walls in winter?

Yes, but cold-weather concrete requires heaters, insulating blankets, and special mixes to avoid cracking and poor curing.
