$30 and $40 per square foot.
Poured Concrete Wall Costs. Concrete prices vary widely by region of the country and time of year. Ready-mixed concrete will cost between $65 and $90 per cubic yard (3’x3’x3’) . To put this into perspective, a wall 9’x27’x12” thick would take 9 cubic feet of concrete. 1 Poured concrete costs about $30-$40 or more a square foot (usually with a minimum charge for small jobs), or about $1,500-$2,000 for a wall 30 inches high and 20 feet long. Some companies have reusable concrete forms to build walls and this keeps their costs down. These companies typically charge about $3 to $5 per square foot of wall (disregard thickness of the wall). Other companies build concrete wall forms from scratch for each job and this drives cost slightly higher. Concrete Wall Prices. In home construction, poured concrete walls are, normally, installed below grade. They are found in a basement, or in a split-level house that has a 3 to 4 foot high retaining wall, on top of which the rest of the house sits. For Ralston, $39 per square foot is the average cost he charges for a wall under 4 feet tall. For walls below 4 feet, he says his prices are often competitive with finished block. A block wall has to be stuccoed or finished with veneer, while a concrete wall does not need an added finish. Retaining Wall Cost. Poured retaining walls with elaborate curves require complex formwork and will drive up cost for a wall. The total cost to have a concrete retaining wall installed will be a combination of material and labor prices. For a basic wall you can expect to pay between $30 and $40 per square foot. If you add a decorative finish, curves, steps, lighting or other upgrades, the cost will rise.
