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.
Labor costs will vary depending on the company you hire. 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.n 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.
