Spring is here and it’s time to put a little work into your yard. Maintaining your lawn is one thing but what if you want a garden? Planting a flowerbed is a nice addition but how about you take it to another level; by adding levels. Building small CMU retaining walls in your yard or against your house will make your yard look fuller and more beautiful.
What is a CMU retaining wall?
CMU stands for Concrete Masonry Unit. It’s a standard size block used in the construction of walls and buildings. A retaining wall is exactly what it sounds like. It’s a wall that holds back soil from spilling down or eroding. It’s especially useful, and possibly needed if you have a yard that slopes, but it can be applied just for design as well.
Retaining walls can be made of CMU blocks, bricks, stones, and wood. They all look attractive but CMU blocks are the sturdiest. Just like sidewalks, CMU walls can be made stronger by adding rebar to the structure; rebar stands for Steel Reinforcement BARs. You’ll want the wall to be as strong as possible because it may, believe it or not, have to hold back 1 to 15 tons of soil depending on how tall and long the wall is. The length of the wall can vary to your needs but the height should remain within 3 to 4 feet high. It’s low enough for you to reach over and tend to your garden and it’s also a good height to easily sit on. A taller wall can be built but it will need more reinforcements to stabilize it and an engineer will need to be hired to design it.
