Retaining wall costs can vary depending on the material. Some of the most common materials include poured concrete and cinder blocks. Cinder blocks are made from coal cinders and cement, and they tend to have a lower density compared to concrete.
However, cinder blocks and concrete blocks are still very similar. According to the National Concrete Masonry Association, "These masonry units are essentially the same product produced with the same three basic constituent materials: water, cement, and aggregate." Talk to professionals near you to see what your options are regarding materials. For example, instead of concrete or cinder blocks, you may want to build a stone retaining wall made out of flagstone. Or, you can even use wood and timber for your wall. Railroad tie retaining wall cost

The national average cost for a railroad tie retaining wall is $1,993. However, low-to-high national average prices range from $1,706-$2,651.
If you want your wall to have a more rustic aesthetic, consider railroad tie retaining walls. Railroad tie retaining walls contain treated wood reclaimed from railroad tracks. They tend to cost less than cinder blocks and concrete retaining walls.
However, railroad ties aren't as strong as concrete or cinder blocks. And even though it's treated, the wood may rot over time. Some professional builders may not even offer railroad ties for your retaining wall because the wood is treated with creosote.
Creosote "poses cancer and non-cancer health risks of concern to workers in wood treatment facilities," according to the Environmental Protection Agency. However, the EPA "did not find health risks of concern for the general public, nor for workers who handle creosote-treated wood after application." Talk to your builder if you're interested in a railroad tie retaining wall. Find out if they recommend it for your landscape design. Retaining wall cost factors
As you consider equipment, material and labor expenses, keep in mind these additional factors that may affect the cost of a retaining wall project:
Demolition required. If you need to remove an existing wall or clear out shrubs or trees, that will add to labor costs.
Wall location. Hard-to-access job sites will typically cost more due to the additional labor or equipment needed. If your wall is built on uneven terrain, that can also increase labor costs.
Design needs. A complex design that includes stairs, curves, seating, textures, color, openings, etc., will likely be more expensive.
Height. You may need a permit if your retaining wall is very high (usually more than 3-4 feet, depending on where you live). Permits often come with fees.
Additional details that require a permit. You may also need to get a permit depending on various factors (if there's an attached solid fence, there's a sloping backfill, etc.)
You'll also want to consider long-term maintenance and repair costs. At some point, you may need to:
Fix any cracks, settling or bulging
Reinforce your retaining wall
Ask your contractor how to properly maintain your wall and how much it typically costs to have a professional perform repairs.
How can I reduce the cost of a retaining wall?
You may be able to lower your retaining wall costs by selecting less expensive types of natural stone and other materials. Chat with your contractor to see how much they charge for different materialsYou can also try the following tactics:
Do some of the work yourself (like preparing the area or site).
Find out if you can recycle existing concrete from another project, like a driveway demolition.
Bundle concrete projects or hire a landscape professional to tackle multiple projects at once. You may be able to get a better deal using a single contractor instead of multiple.
