Is a retaining wall the same as a landscape retaining wall?

Is a retaining wall the same as a landscape retaining wall?

In essence, yes. Retaining walls are designed to optimise the land it is erected in by keeping land organised. This is usually through creating a wall that retains land that was originally sloped. Retaining walls can vary in size.

Additional benefits of retaining walls include…

  • It can help to maintain health and safety.
  • It can be used to create pathways that were not available or viable before the wall was made.
  • If installed correctly, it can promote healthy drainage of rainwater, which prevents large puddles from forming.
  • Creates an organised aesthetic.

Landscape retaining walls are similar in function to a regular retaining wall. However, the key difference is that a landscape retaining wall will likely have features that optimise the space or have a specific aesthetic goal in mind.

A common example is a retaining wall that is separated into different levels in which you can plant flowers in. This kind of application is great for those with a green thumb and looking for an easy way to grow their plants and still keep them separate.

Good vs bad retaining walls

A good retaining wall…

  • Has no puddles forming behind the wall when it rains.
  • Features drainage.
  • Is vertically straight.
  • Has no gaps in the wall.
  • It is secure and cannot be moved.

A bad retaining wall…

  • Has puddles forming behind the wall due to improper or no drainage.
  • It is bulging, or not vertically straight, due to a lack of reinforcement and proper drainage.
  • Has gaps in the wall.
  • Has leaks coming from the wall.
  • Individual parts of the wall can be moved.

In a vast majority of cases, bad retaining walls are created due to people undertaking the project with a lack of knowledge and experience. We strongly recommend the services of a professional to help you with your retaining wall.

Building a landscape retaining wall

Is a raised garden bed the same as a retaining wall?

Building a landscape retaining wall can present further challenges from a typical retaining wall. Though, this is entirely dependent on the plans submitted by the landowner.

The reason landscape retaining walls may pose more of a challenge is because there may be aesthetic choices made such as the path of the retaining wall. (Curved or wavy rather than a straight wall).

What’s more is that if the landowner wanted separate divisions in their retaining wall, that would require further planning and work. In this instance, consultation from a landscaper would be imperative to complete this task.

There is more than one way to construct a landscape retaining wall. Though, it can be argued that one of the most full-proof options available to you is employing the use of Interlocking Concrete Blocks.

Why are Interlocking Concrete Blocks good for a retaining wall?

Interlocking Concrete Blocks are perfect to use for making a retaining wall for the following reasons…

  • Interlocking Concrete Blocks require no binding materials in order to create a secure and lasting connection. Simply align the recesses of the block you will place in conjunction with the studs of the block below it.
  • Interlocking Concrete Blocks come in many sizes. This makes them perfect for retaining walls of any scale.
  • Interlocking Concrete Blocks are heavy, especially once they have interlocked. This increased centre of gravity makes it almost impossible to topple without a significantly strong force.
  • Due to being made from concrete, Interlocking Concrete Blocks also have a respectable level of durability attached to them. Although your retaining wall won’t be under constant forceful impacts (we hope!) It is reassuring to know that it is strong enough, just in case.
  • Interlocking Concrete Blocks are essentially weatherproof. They are not affected by freezing temperatures or significant heat due to weather, or any flames.
  • Our Interlocking Concrete Blocks also come as ‘Rock Face Blocks’ which swap the standard plain grey facing to an aesthetic, natural looking rocky front. Alternatively, choosing the standard facing option is fine, as you can paint it to achieve your own unique look if you so choose.

Should I use a landscaper for a landscape retaining wall?

If you have no experience in landscaping, or erecting a retaining wall, seeking the guidance and services of a landscaper could be vital. Even in the planning phase, a landscaper would be able to show you further ways for you to maximise the use of the space if it is possible.

Interlocking Concrete Blocks are not the only option you can use for a landscape retaining wall, and a landscaper can help you explore other options if you decide to.

Although it could be costly, the level of expertise you are paying for is definitely worth it. You can easily find a reputable landscaper through a simple search on the internet.
