Things you should factor in before building a retaining wall in your backyard

When creating beautiful gardens around the property, you may think of the typical landscaping – potting plants, planting a new lawn or setting up vegetable garden here and there. What about building a retaining wall to reclaim the slope?

A retaining wall is not just a 4-feet or so stone wall that holds back earth but a means to spruce up your outdoor panorama. In fact, you can cater the outdoor needs and personal tastes alike thanks to the modern-day retaining wall design ideas. A well-built retaining wall should last for 50 to 70 years or more. That means it’s a big investment of time and money.

Now you might be super inspired to rush out to the local home improvement store and grab the materials you need. Hang on – unless you know what you’re doing, a DIY retaining wall can turn out to be a huge disaster. Your best bet is to consult the professional retaining walls builders in Perth.

The guide below will walk you through a few things that you should consider before scheduling work for the retaining wall.

Know the property plans

A good place to start with is to understand the scaled map of the property. Good knowledge about the property lines including water, electricity, sewer, and gas will come handy during the planning and designing stages. Plus, you can ensure everything is in line with the local and state regulations.

Soil characteristics

The type of soil on your property dictates the materials and techniques to be used, and of course, the duration of the project. Well-draining sandy soils are better than the clayey ones. Heavy clay soils hold water for a long time. If you have clayey soil you might have to remove or replace it with higher quality soil. Though replacing soil may add to the overall cost, poor soils may interfere with the durability and longevity of the retaining wall.


A retaining wall can be created from several types of materials. Whatever material you use, make sure it is on the same page with the style, purpose, and budget. The commonly used materials to build a retaining wall are,

  • Stones – Stone walls are the most popular as they jell well with all styles of yards.
  • Bricks- Best suited for landscapes and traditional homes, brick walls are durable and affordable. But this one may need special drainage accommodations.
  • Timber- Timber walls are easy to work with and are pocket-friendly. Treated pine sleepers and hardwood sleepers are popular among conventional-style homeowners.
  • Concrete- A great option that provides maximum strength, durability, and longevity. In fact, the blocks come prefinished to save time and money. Additional perk: they’re suitable for almost all home exteriors.


Check if there is water runoff in the location. When building a retaining wall in a location with runoff, the landscaping experts need to divert the water carefully. This way the damages to the property or the newly built wall can be prevented.

The height of the wall

In general, the retaining wall needs be a few inches taller than the ground level. This ensures that the heavy rainfall doesn’t easily wash away the soil. Also, you should decide whether you want to retain the natural slope or want it to be of the same height throughout.


Though there are many, many factors to consider before building a retaining wall, these five are great to start with. As we mentioned earlier building a retaining wall is an investment – functionally and aesthetically. So, don’t fall for DIYing buzz, especially if you have a hilly yard or clayey soil in your property.
