Poured Concrete vs Timber Retaining Wall
Poured concrete and timber walls differ in structure, durability mechanisms, and site limitations. Compare retained height, loads, soil, drainage, treatment, connections, access, engineering, and replacement expectations.
Default context: 50-foot wall with 3 feet of wall face (150 square feet).
Poured Concrete
$20 to $45 per sq. ft.
Arithmetic size example: $3,000 to $6,750
Installed poured wall priced by wall-face area; the cited range primarily covers walls 3 to 6 feet tall. This is planning arithmetic, not a bid.
May matter when
- Formed to project geometry
- Reinforcement and footing designed as a system
- Can receive architectural finishes
Verify before choosing
- Requires forming and professional placement
- Access and engineering can dominate cost
- Future repair or modification can be disruptive
Timber
$15 to $30 per sq. ft.
Arithmetic size example: $2,250 to $4,500
Installed wood or timber retaining wall. This is planning arithmetic, not a bid.
May matter when
- Natural landscape appearance
- May suit some short residential walls
- Published starting range is below poured concrete
Verify before choosing
- Wood treatment, hardware, drainage, and soil contact affect the system
- Local rules and height limits vary
- Replacement and deterioration expectations should be discussed
Decision framework
Timber has the lower published installation range. Poured concrete may fit a formed reinforced wall system, while timber may fit some shorter landscape applications when local requirements allow it.
Concrete may fit when
The design calls for a formed reinforced wall and long-term access for replacement would be difficult.
Timber may fit when
A qualified designer or contractor confirms timber is suitable for the wall height, loading, drainage, treatment, and local requirements.
Questions to resolve for this comparison
- Are timber treatment, hardware, connections, drainage, and soil-contact details specified?
- Do wall height, surcharge, soil, and local rules allow the proposed system?
- How would future inspection, repair, or replacement access work?

Published ranges use different scopes and do not represent averages of contractor bids submitted to Contractors for Concrete. Small projects may be subject to contractor minimum charges that straight square-foot multiplication does not capture. The calculator multiplies area by installed price only. It does not estimate maintenance, service life, financing, resale value, or replacement timing.
