What Is The Best Block To Use For A Retaining Wall?
When choosing the best block to use for your retaining wall, there are some aspects to consider. How much experience do you have a building? What are your expectations when it comes to cost? How much time do you want to dedicate to this project?
After considering these questions, you can choose the type of block that is best for you. Let's take a closer look at some block options and their pros and cons.
Uni-lock Segmented Blocks

Each type of block holds unique benefits. Overall, concrete blocks are best when it comes to different options within the material, costs, and workability.
