Poured concrete wall cost per linear foot commonly falls between $150 and $350 for a standard residential project, with shorter or simpler walls sometimes costing less and engineered retaining walls costing more. Height, footing size, excavation, reinforcement, access, and local labor rates are the biggest price drivers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed wall per linear foot | $100 | $225 | $450 | Typical 6- to 8-foot residential wall; scope and height matter |
| Installed wall per square foot | $15 | $28 | $50 | Wall face area, not floor area |
| 40-foot wall project | $4,000 | $9,000 | $18,000 | Before unusual soil, drainage, or access work |
| Concrete material | $125 | $175 | $225 | Per cubic yard, excluding delivery surcharges |
Assumptions: U.S. residential labor, ordinary access, standard concrete strength, and a straight wall with no major rock excavation.
What poured concrete walls cost per linear foot
For budgeting, a basic 4-foot wall may run about $100-$200 per linear foot, while a 6- to 8-foot wall often lands around $150-$350. A tall, heavily reinforced retaining wall can reach $300-$600 or more per linear foot when it needs a wide footing, engineered drainage, difficult excavation, or substantial structural design.
A typical 8-foot poured wall averages about $225 per linear foot, but wall height and project scope can move the quote sharply. The estimate should state whether the price includes excavation, footing, rebar, forms, concrete placement, waterproofing, backfill, and cleanup. If a contractor quotes only the wall face, the total installed project price will be higher.
How excavation, forms, and rebar shape the quote
Concrete itself is only one part of a poured wall estimate. Labor-intensive forming, steel reinforcement, excavation, and concrete placement can account for more than the material bill. The table gives common installed-cost shares for a standard residential job; site conditions can shift them.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Excavation and footing | $20-$65 per linear ft | Digging, base, and footing concrete | Depth, soil, equipment access |
| Forms and stripping | $30-$80 per linear ft | Form rental, setup, removal | Wall height, corners, bracing |
| Rebar and placement | $20-$60 per linear ft | Steel and installation labor | Spacing and structural design |
| Concrete and pumping | $25-$75 per linear ft | Concrete, delivery, placement | Wall volume and truck access |
| Waterproofing and drainage | $10-$45 per linear ft | Coating, drain, or aggregate | Below-grade use and water pressure |
Labor commonly costs $50-$100 per hour per worker, though wall quotes are usually bid by project rather than by the hour. A rough labor calculation is . Ask whether the bid includes equipment, disposal, delivery fees, and form rental so those charges are not mistaken for unexpected extras.
Wall height, thickness, and soil conditions change price
Height is a major cost lever because each additional foot increases concrete volume, form height, bracing needs, and sometimes reinforcement. A 4-foot wall is not simply half the price of an 8-foot wall: both may require mobilization and footing work, while taller walls usually need stronger engineering and more labor.
Walls over 4 feet of retained soil often trigger additional engineering or local code requirements, and walls around 8 feet commonly need a structural design. A 6-inch wall may work for some applications, while an 8- to 12-inch wall or thicker footing can be required for heavier loads or poor soil. Rock, groundwater, sloped sites, and restricted machine access can add $20-$100 or more per linear foot.
Foundation wall and retaining wall quotes differ
A basement foundation wall is typically built to support the structure above and may need waterproofing and footing drainage. A retaining wall must resist lateral soil pressure; drainage stone, a perforated drain, stronger reinforcement, and engineering may therefore add substantial cost. A freestanding landscape wall has different structural demands and should not be priced as though it were a basement wall.
Compare quotes only when they cover the same wall type, height, footing, reinforcement, and drainage scope. A contractor may quote foundation work by linear foot, while another prices the same job by wall-face square foot. For a 40-foot-long, 8-foot-high wall, the face area is 320 square feet; at $15-$50 per square foot, that suggests $4,800-$16,000 before scope adjustments.
What a 40-foot wall project can cost
These examples show how scope affects the total. They assume residential work and ordinary local access; they are planning estimates rather than guaranteed bids.
| Example | Wall specification | Approximate total | Included scope |
|---|---|---|---|
| Short garden wall | 40 ft long × 3 ft high | $3,500-$6,500 | Basic footing, forms, concrete, modest reinforcement |
| Basement wall | 40 ft long × 8 ft high | $6,000-$14,000 | Footing, formed wall, rebar, standard placement |
| Engineered retaining wall | 40 ft long × 8 ft high | $12,000-$24,000+ | Reinforcement, drainage, more involved excavation |
Totals can exclude permits, design fees, waterproofing, backfill, and difficult-site work. For a useful comparison, request separate line items and confirm the measured wall length and height. A minimum mobilization charge may also make a short wall more expensive per foot than a longer run.
How long crews need to pour and strip forms
A straightforward residential wall may take a crew of three to five workers about 2-5 workdays for excavation, footing, forming, reinforcement, pouring, and stripping. The concrete needs time to gain strength before forms are removed or heavy backfill is placed; weather, access, inspections, and curing instructions affect the schedule.
Labor time rises when corners, steps, tight access, or hand excavation slow form setup and concrete delivery. A pump truck may add roughly $500-$1,500 when the site cannot be reached by a concrete truck chute. Ask whether the quote includes pumping and whether crew return visits for stripping and backfill are included.
Regional labor and access shift concrete wall rates
Prices often run 10%-25% above national midrange in high-cost metro areas and about 10%-20% below it in some lower-cost rural markets, though rural delivery distances can erase part of the savings. Local concrete supply, contractor availability, permits, and seasonal demand also influence bids.
Site access can outweigh regional averages when trucks or forms cannot reach the wall directly. Tight urban lots may require pumping or manual handling, while remote sites may face mileage and delivery minimums. In cold regions, frost-depth footings and winter protection can add cost; wet climates may require more drainage or waterproofing for below-grade walls.
Where scope cuts lower a poured wall estimate
Keep the design aligned with the actual load rather than paying for unnecessary height, thickness, or decorative finishes. Confirm whether a shorter wall, stepped layout, or different placement can meet the engineering plan. Avoid reducing rebar, footing dimensions, or drainage without approval from the designer or building authority.
Compare at least three itemized bids using identical drawings and specifications. Clearing the work area, arranging access, and coordinating excavation with other site work may reduce crew delays. Bundling a wall with nearby concrete work can sometimes lower mobilization charges. Check whether repair of a limited damaged area is feasible before replacing an entire wall, but use a qualified professional to assess structural cracks or movement.
