The cost to build a retaining wall ranges from $28.50/SF to $79.12/SF. Factors affecting the price include wall height, material choice (concrete blocks, decorative blocks, or natural stone), soil conditions, drainage requirements, and accessibility. Engineering plans may be required for walls over 4 feet tall, adding to the overall cost. The estimate includes necessary base preparation, drainage system, and proper backfill materials.
Wall and ground preparation
The listed scope includes wall blocks or stone, excavation, base preparation, drainage materials, backfill, and equipment rental. The selected wall material needs to match the bid rather than remain a broad allowance for any block or stone.
Height, soil, and access
Wall height, soil conditions, and access affect excavation and construction time. Drainage pipe, filter fabric, and gravel are separate parts of the scope that should stay visible when comparing wall bids.
Engineering is a separate selection
Engineering plans are an optional item in this estimate. Confirm the wall design and any needed plans or permits for the actual site before bidding; do not assume that the calculator selection settles those requirements.
