Retaining walls are always a great idea for your garden, but they can also weigh heavily on your wallet. Luckily, there are several alternatives to standard retaining walls such as recycled tires and weathered steel. Whether it be timber stumps or stacked stones, let’s take a look at the 25 best retaining wall ideas.
If you are experiencing the issue of irregular ground around the exterior of your home, consider installing a retaining wall. A retaining wall is a landscaping structure that holds soil back on one side.

Retaining walls have an architectural and artistic quality that can add definition and completely transform your property. By incorporating retaining walls into your flowerbeds and gardens, you can create a beautiful landscaping masterpiece. Depending on your desired style and budget, they can be made from various materials.

Gravity Retaining Wall
Beginning with the gravity retaining wall, this type is exactly as it sounds. The most basic option, it uses sheer weight and mass to hold the soil back. Choosing this type offers you plenty of variety when it comes to materials since it’s mostly about weight.
A few options available include pavers, bricks, stone, concrete and any other heavy materials. Because of the weight, they typically don’t require any additional reinforcement. You’ll only need to dig a small trench for the wall to sit into.
Sheet Piling Retaining Wall
A sheet piling retaining wall is simply a thin wall of vinyl, wood, steel, aluminum or fiberglass that is installed straight into the soil. You might opt for this type if space is an issue on your property as they can be placed in very tight areas.
Usually used in soft soils, sheet piling is generally driven 1/3 above ground and 2/3 below ground. However, this may change based on the environment. Additionally, if you’re choosing to construct a taller sheet pile wall, they will likely need a tie-back anchor for supplemental reinforcement.
Cantilever Retaining Wall
Cantilevered retaining walls are constructed using reinforced concrete. They are the most common kind of retaining structure. Their design works on the principle of leverage with a thin stem and employ the weight of the backfill soil to prevent any shifting.
The main benefit of this type of wall is that it typically uses less material than a more conventional gravity wall.
Anchored Retaining Wall
While most of the other types work best with short walls, a considerably high retaining wall can be built using this structure system. Wires or cable rods are mechanically driven deep into the ground on an angle.
At the end of the cable, anchors are then expanded either by use of injecting pressurized concrete or other mechanical methods. This particular retaining wall can be employed on any of the other types for additional support and is often used for physically thinner walls.
Retaining Wall Materials by Price
After you’ve decided on the type of retaining wall that will work best on your property, you’ll need to consider materials. Take a look at the environment where you’ll be installing the wall to choose what will complement it best.
At this stage, it’s important that you have a budget in mind because the pricing will vary. Massive retaining walls that utilize heavy materials like stone and brick are effective and look beautiful but can be costly.
However, if you’re on a tight budget, opting for a more inexpensive retaining wall material can look just as appealing as an expensive option. Here are some typical materials and where they land in regards to pricing:
- Concrete Blocks – This material is a very contemporary and refined option. They are relatively easy to install, low maintenance and can produce very durable, long-lasting retaining walls. Pricing for concrete blocks are generally very uniform and will run you around 1-3 dollars a block.
- Brick – Brick is a very popular and desired building material for homeowners since they can complement most traditional homes. Although they are a very sturdy and require little upkeep, they fall in the upper price range of materials. You can expect to pay an average of $14-$15 per square foot.
- Wood – Like brick, wood is very versatile and can pair well with most landscaping. The natural look will effortlessly blend into your overall design. Although wood has the shortest lifespan when compared to other materials, with proper maintenance your wall can last a good 20 years. Using wood offers a great DIY project since they are easy to install and are likely your most cost-effective option. Wood retaining wall pricing typically starts at $15 a square foot.
- Natural Stone – Stone is considered to be one of the more pristine building materials. It’s beautiful, looks great in any rustic setting and is a very strong, resilient resource. However, it’s considered to be the most expensive on the market and depending on the type of stone you use, will cost you $8-$12 a square foot. Also, because of the sheer weight, it can be a very labor-intensive endeavor so you might want to hire a professional.
- Timber – While wood is a term that refers to the element trees are made of, timber is any phase of the wood after it has been cut. If you choose thick timber pieces, they can be much heavier and stronger than basic wood planks. Although they are not as long-lasting as other resources, they are generally very affordable. Your cost of installation for a timber retaining wall will be between $16 and $19 per square foot.
- Limestone – Limestone pieces come in varying colors and shapes and can be adapted to your desired look. They are also fireproof, weather and impact resistant and easy to keep clean. Since there are so many variations on the market, their cost can be difficult to estimate. However, as an example, weathered limestone can cost up to $515 per ton.
