What Is A Retaining Wall?
A retaining wall is normal used to hold back soil, rocks, and other things that have a chance of falling into a home or business. There are many different things that retaining walls can be made out of but concrete building blocks are still a very popular decision.
The reason for this is the ability to keep the strength of concrete, but also being able to make it look like other things like river rocks, boulders, etc.
Another great advantage with using concrete blocks is also that if there is a part of the wall that gets damaged you can fix that part easier, and won’t have to tear down the whole wall.
There are a few different types of retaining walls that you can build to make sure that gravity doesn’t push it down, or anything else damages the wall. The thing you have to do is pick the best type of retaining wall for you.
There are many things that you have to take into consideration, like how tall the wall is going to be, how big is the slope behind the retaining wall, and how much earth will be behind that wall when it is complete.
The biggest damaging factor to retaining walls is gravity. The reason you have to make walls that can withstand gravity is because normally there is a lot of dirt that is being held back with a retaining wall. If the wall is not made properly it will either topple over, or be pushed out from the bottom.
There are several ways you can make the wall so this will not happen.
Different Types Of Blocks Used
There are different block that you can use, there are cinder blocks, there are finished blocks that look like flag stone, or river rock, there are even very large piece of concrete that you can use where the face looks like multiple rocks. These larger piece of concrete weigh around 2400 pounds. and are easily stacked. These are ideal in situations where you have a lot of soil behind the walls with no other way of holding it back. These can hold back a very large amount of soil or whatever you have behind the wall.
Concrete retaining walls are normally between 26 and 32″ thick, there is normally rocks behind the wall to add more stability to the concrete wall. The concrete block is also a couple inches below the ground level, this stops the earth from just pushing the retaining wall out of the way.
Depending on what type of concrete block you are using there is also concrete poured into the hallow parts of the blocks to make it more sturdy. And before that poured concrete is dried they also drive down re-bar into those hows to give the wall even more stability. These are a couple things that you do not have to do, but it may help you wall last longer.
