How To Build A Wall With Concrete Blocks

When you’re building a wall, it’s important to follow the right steps and use the right materials. If you don’t know what you’re doing, a poorly-constructed wall can fall apart or look terrible. However, if you do your research beforehand and have some patience and skill, building a wall will be a breeze! In this beginner’s guide, we’ll cover everything you need to know about using concrete blocks to build a sturdy new wall. So roll up your sleeves and get ready to learn how to lay out your blocks like an expert

Step 1 – Planning

Before you start building a wall with concrete blocks, it’s important to plan for the job. This is because there are many factors that need to be considered before you begin building. These include:

  • The purpose of the wall. Is it for security? To divide space? Or just for decoration?
  • The location and appearance of your block wall. For example, do you want to make it look like a Tuscan villa or something more modern and sleek?
  • Construction details such as size, shape and height; type of mortar used in between each brick; how much cement needs to be used; how many bricks are needed per cubic meter (for example 20cm x 20cm x 40cm = 160 bricks). This can all impact on cost or even how long it’ll take before everything dries properly so that no moisture damage occurs through cracks or leaks over time!

Step 2 – Lay Down A Foundation

Once you’ve laid out your foundation, use a leveler to ensure that it is level. Then use the same tool to check that each corner of the foundation is square, and finally, make sure the entire foundation is plumb (vertically level).

Next, create a concrete base using cement mix according to directions on its bag. The size of your blocks should dictate how much concrete you need; this will also depend heavily on what style of block you choose—some shapes require more than others do.

Step 3 – Set The First Block In Place

You will be setting a block, or row of blocks, in place on top of the footings. For this tip you will use your level and plumb bob to make sure that the first row is level and straight, as well as aligning it with other rows.

To set a concrete block:

  • Position the base plate flush against the footing so that there is no gap between them.
  • Use your level to make sure it’s level across its length. If necessary, add or remove material from under one end until you have achieved a good position for your first block (see photo).
  • If necessary, use your plumb bob to make sure that each side of the block is vertical by positioning it against one side of the block and then releasing it so that gravity pulls it down until it touches where you want to mark (see photo). Once again adjust as needed until correct alignment is achieved.

Step 4 – Fill the Block Cavities and Lay The Next Blocks

  • Fill the Block Cavities and Lay The Next Blocks

Fill each cavity with concrete using a trowel, then use a leveler to check that the top surface of each block is level with the next. You can also use a chalk line to ensure your vertical alignment is correct.

Lay the next block in place, pressing down on it firmly until all air bubbles have been forced out of its cavities and it’s flush against its neighbor (you may need to tap it gently). Repeat this process until you reach your desired height—but be careful not to exceed 8 inches (20 cm) of wall thickness unless you are building an interior partition for heavy loads such as garage doors or walls between rooms.

Step 5 – Use a Leveler to Ensure Vertical Alignment

Measure the level of each block and make adjustments as needed. Use a leveler to ensure vertical alignment, and then use it again to make sure they are straight. If you couldn’t see what was going on at the bottom of your wall during construction, you’ll definitely want to use a leveler now that your wall is finished.

To ensure vertical alignment, place one end of a block against the frame and hold it there with one hand while using the other hand to slide another block beneath it until it rests against this new block (the “toe”). The two blocks should be touching perfectly flat against each other on both sides so that when held together in this way by hands (or clamps), they form a perfect 90-degree angle between them–exactly like how we measured before.

Step 6 – Spread Concrete On Top Of The Wall

After the concrete has dried for 24 hours, you can remove the plastic sheeting. Now it’s time to do some final leveling and smoothing of the wall. This is a critical step in creating a functional and aesthetically pleasing concrete block wall—you want to make sure that there are no bumps or dips in your surface.

To smooth out bumps, use a trowel and scrape away excess concrete from around any protruding spots on your wall. Try not to get too aggressive with this as you don’t want to chip off any of your blocks or create divots that will look unsightly when they dry (as they will). Just try scraping away at areas where there are bumps until they disappear or become smaller and feel flat when pushed against with your hands. You may also choose to use an orbital sander (a power tool) instead of hand tools if this is easier for you

Now that we have our base ready, let’s build our first row

Whether you are building a retaining wall, boundary wall, garden wall or just a feature wall, here’s how to build a basic block wall.

Regardless of the project, it is vitally important that you plan ahead. A good foundation will ensure your wall stands strong and vertical. This can be as simple as digging out the earth at the base of your wall using a spade to create a solid footing for each block, or something more elaborate like excavating a trench around the perimeter of your wall on which to lay steel reinforcement rods or even concrete poles.

Once you have laid down your foundation, you need to make sure everything is level and aligning with one another. You can do this by fixing a long straight board along the top of your wall (or if it’s not too high), then use a spirit level to check that both sides are equal in height. If necessary, use stakes or pieces of string tied between two nails hammered into each corner block — they should be level if all other things have gone well


So, you should consider building a wall. In this article we’ve shown you the steps you need to take in order to build your own concrete block wall from start to finish. Hopefully this has helped some of you out there who are struggling on how exactly they would go about doing this project.

In conclusion, I am happy with the results and see the potential in applying these methods to other domains in my work enviornment. I would like to continue improving my skills through practice with real datasets and eventually automate the process into a standalone tool that can be deployed by anyone.
