Nature’s uneven and wild terrain is undoubtedly magical.
However, a lot of that magic seems to dissipate once you try to have a romantic wine dinner on your uneven patio or try to play a game of badminton on a giant slope.
That’s why many people choose to install a retaining wall as a backstop: it carves out a practical and fully-functional space for you to enjoy any activity outside.
On top of creating manageable outdoor spaces, retaining walls also create a unique sense of definition to the landscape and your yard.
They come in all sorts of different styles and forms to create a personality as well. From rustic stacked timber to modern poured concrete, you can create stunning walls, based on your personal style.

The Basics of Retaining Walls
First things first, when planning to implement a retaining wall that’s designed to hold back literally tons of soil, there’s very little wiggle room left for error.
The effectiveness of your wall and its longevity depends on factors you can’t see, such as drainage and a solid footing in the ground.
For this reason, and many others, we highly suggest you don’t take on a retaining wall as a DIY project unless you already have a lot of experience.
On top of managing sloped areas, retaining walls can also be used on ground level to help raise up living spaces. They can elevate planting areas for better drainage while also creating a seawall.
There are so many benefits and ways to use these personalized walls. However, they can also be quite costly.
Let’s look at some of the basics first.
How Much Do They Cost?
Poured concrete retaining wall prices begin at $4.30 per square foot, while interlocking concrete block walls are $5.65, $11 for stone and $6.15 for treated pine.
This doesn’t include filter fabric, drainage stone, installation or supplies.
Will They Last Long?
It all depends on who installs it and how they do it.
When done properly, these walls last a long time.
There’s no limit for the lifespan of concrete or masonry wall that’s installed properly. In comparison, walls made of timber can last for up to 40 years.
Pro Job or DIY?
A lot of people will recommend interlocking concrete block walls and timber for DIY projects, but poured concrete and masonry jobs are clearly best left to a professional.
While it is possible to install a retaining wall on your own, there’s a lot of factors that need to be considered in order for the wall to be successful, long-lasting and most importantly, safe.
However, if you’re confident and have the proper instructions, you could do this job yourself.
The Anatomy of a Retaining Wall
There are some basic parts for a generic mortared-stone wall.
If you’re planning on getting at your retaining wall idea yourself, it’s important to keep these basics in mind.
Components used for other types of retaining walls vary.
For a basic mortared-stone retaining wall, you’ll need:
- Drainage stone to keep water from collecting behind the wall
- Filter fabric to prevent soil from clogging your drainage stone
- Weep hole to allow water to drain through the base of the wall
- Proper footing which is reinforced supports, usually concrete, for the wall
- A footing drain to carry the water away
Retaining Wall Complications
A magical aspect of retaining walls is their incredible strength.
They're able to carry loads which is created by more than soil weight. Water that’s collected from behind the wall creates hydrostatic pressure. This is the cause of most wall failures.
Only properly designed drainage walls and waterproofing systems can ensure wall survival.
In fact, building permits will require these specific calculations since retaining wall failures can cause a lot of damage.
This is especially important in areas where slopes are unstable and the climate experiences heavy rain that may lead to ultra-saturated soils and horrific mudslides.
You should always remember that no matter how beautiful these structures may be, they’re powerful and need to function as designed.
This can only occur when they’re made from adequate materials and created by high-quality contractors.
However, once you nail down these two aspects, you’ll be able to create a stunning wall that stands strong and proud for decades afterward.
