Types of Inexpensive Retaining Walls

Creating a retaining wall doesn’t have to be an expensive project. There are a variety of materials that can be used to create a sturdy and stylish structure without breaking the bank. Let’s explore some of these economical options.

Timber Wall

Timber, specifically pressure-treated pine, is a cost-effective choice for a retaining wall. With prices starting from $6.15 per square foot, it’s a real budget-friendly option. Not only is it cheaper than stone or concrete, but it also adds a warm, natural look to your landscape. Short walls under three feet high are the easiest for DIYers to build. They are ideal landscape solutions for a front yard or raised flower bed. Remember, the cost of additional supplies such as drainage stone or filter fabric isn’t included in this price.

Cinder Block Wall

Cinder block or interlocking concrete block walls offer another inexpensive yet durable option. They’re slightly more expensive than timber, with prices starting at $5.65 per square foot. However, these blocks are easy to install and offer versatility in design. They’re readily available at most home improvement stores. Besides, they allow for a variety of textures and colours, enabling you to match the wall with your overall landscape design.

Natural Stone Wall

Finally, natural stone is a pricier option, with costs starting at about $11 per square foot. However, it creates a beautiful, timeless look that is well worth the investment. Stone walls are durable, sturdy, and efficient. Although it’s the most expensive option mentioned, using natural stone can add significant value to your property. For an even more budget-friendly alternative, consider railroad ties. These large, sturdy wooden beams are a popular choice for gardeners working within a strict budget.

Decorative Options for Inexpensive Retaining Walls

So you’ve settled on the type of retaining wall you want. Now it’s time to inject some personality and make it your own. Here’s how you can transform these inexpensive retaining walls into a design feature.

Paint or Stain

A quick and easy way to lift the look of your retaining wall is with paint or stain. Whether it’s the natural stone, timber or cinder block wall, all lend themselves well to a bit of colour.

Paint offers a vast range of colours and finishes. Want a sleek, modern look? Go for a muted, matt finish.

Stain, on the other hand, enhances the natural beauty of your timber or stone wall. Opt for a darker shade to create a contrast with your garden’s greenery.

It’s all about your style, your personality. So, don’t hold back on expressing yourself.


Incorporating plants can instantly soften the look of your retaining wall. For instance:

  • Climbing plants are a great way to make your wall blend with the rest of your garden. Think ivy or climbing roses.
  • Low-growing plants like sedum or creeping thyme can be planted in the gaps between the blocks of your wall. They’ll add colour and texture.
  • Tall plants like ornamental grasses or bamboo can provide a stunning backdrop to your wall.

However, do remember to consider the plant’s root system. You don’t want it destabilising your wall.

Decorative Gravel

Finally, decorative gravel can be a stunning addition to your retaining wall design. It’s not just about the aesthetic appeal; it also helps with drainage.

Gravel comes in a variety of sizes, shapes and colours. You can use it to create patterns or simply as a filler.

So, go ahead and personalise that retaining wall. It’s not just a practical addition to your garden, but also a chance to showcase your style.

A gabion wall is a simple and cost-effective solution, providing durability and design versatility. The concept involves using wire mesh cages filled with rocks or recycled materials. It’s a rather straightforward process:

  • Determine the location and dimensions of your wall.
  • Assemble your wire mesh cages.
  • Fill the cages with your chosen material.
  • Stack the cages to form your wall.

The result is a sturdy retaining wall that can withstand the elements. Plus, you can choose the fill material to suit your design ideas, whether it’s colourful rocks or recycled glass bottles.

Pallet Wall

For those with an abundance of wooden pallets, why not turn them into a retaining wall? It’s an incredibly affordable option that still offers plenty of charm. Here’s how to do it:

  • Collect your wooden pallets.
  • Secure them together using long screws or metal brackets.

A pallet wall is a fantastic way to repurpose old materials and add a rustic touch to your outdoor space. You can even paint or stain the pallets to match your outdoor decor.

By employing these DIY techniques, you’ll not only have a functional retaining wall but also a unique feature that adds character to your outdoor space. Remember, a retaining wall doesn’t have to be an eyesore. With a little creativity, it can become a beautiful addition to your garden.

Tips for Maintaining Inexpensive Retaining Walls

After having a closer look at various inexpensive retaining wall ideas, it’s time to delve deeper into the maintenance aspect. Maintaining your retaining wall is crucial in ensuring its longevity and effectiveness. So, let’s dive right in.

Regular Inspection and Cleaning

Regular inspection and cleaning is a must to keep your retaining walls in top shape. Over time, dirt, leaves, and other debris can accumulate on the surface of your retaining wall, leading to potential damage. Keep an eye out for any signs of wear and tear. You’d be surprised at how much a simple hosing down or a gentle scrub can do wonders for your wall’s health and appearance.

Proper Drainage

Make sure your wall has sufficient drainage pathways to prevent this. It’s a simple step that can save you from a lot of trouble down the line.

Repairing Minor Damage

Lastly, don’t ignore minor damages. Small cracks or loose stones might seem insignificant but, if left unattended, can lead to major issues. It’s best to nip these issues in the bud before they escalate. Repairing minor damages as soon as they crop up is a cost-effective way to maintain your retaining wall.

Remember, the key to a long-lasting and effective retaining wall isn’t just about choosing the right materials or designs, but also about regular upkeep and prompt repairs. So, roll up your sleeves and give your retaining wall the care and attention it deserves.
