In Dallas-Fort Worth, a professionally engineered retaining wall costs between $35 and $85 per square foot of face area. A standard modular block wall for a minor slope might run $4,000–$6,000, while a tall, natural stone veneer wall requiring structural engineering can exceed $15,000.
Retaining walls are not just aesthetic; they hold back thousands of pounds of Texas clay soil. Failure is not an option, which is why proper base preparation and drainage account for a significant portion of the cost.
Pricing by Material Type
To calculate the face area, multiply the length of the wall by its height (e.g., a 40-foot wall that is 3 feet tall is 120 square feet).
| Material | Cost per Sq. Ft. | Durability & Use Case |
|---|---|---|
| Treated Timber | $25 – $40 | Fundamental option. Lifespan is limited to 10-15 years due to soil moisture and rot. |
| Modular Concrete Block | $40 – $60 | High durability, clean lines. Ideal for structural integrity and modern aesthetics. |
| Natural Stone Veneer | $60 – $85+ | Premium luxury. A structural CMU core wrapped in natural Texas limestone or flagstone. |
The Hidden Cost: Drainage and Engineering
If a retaining wall fails, it is almost always due to hydrostatic pressure (water building up behind the wall). Every wall we build in DFW—from Arlington to Celina—includes a proper crushed gravel backfill and a perforated French drain system to channel water away.
Furthermore, walls exceeding 4 feet in height typically require a stamped engineer's plan and a municipal permit, which adds $1,000 to $2,500 to the total project cost.
