The first step in building a concrete block house is to prepare the cinder blocks for construction. When the block companies deliver the materials, you will receive cinder block cubes containing around 80 to 90 blocks. To make the blocks more manageable, they need to be broken down into smaller piles of 10 to 12 blocks each. These smaller piles should be stacked approximately 2 feet away from the concrete footer, which will serve as the foundation for your house.

Properly handling and organizing the cinder blocks is crucial for a smooth construction process. By breaking down the large cubes and stacking them in smaller piles, you can easily access the blocks when needed. This step ensures that you have a steady supply of blocks throughout the construction process, eliminating any delays or disruptions.

Take the time to arrange the cinder blocks neatly and securely. By doing so, you create a well-organized workspace and make it easier to locate the blocks as you progress with the construction. This initial preparation sets the foundation for the upcoming steps, ensuring efficiency and convenience during the building process. Once your cinder blocks are neatly stacked and ready, you can move on to the next step of building your concrete block house.

Step 2: Mixing the mortar

In Step 2 of building a concrete block house, you will need to mix the mortar. Mortar is a fundamental component in securing the cinder blocks together, providing the necessary strength and stability to the walls of the house.

To mix the mortar, start by following the instructions provided on the bag. Typically, the ratio is around 16 shovels of sand per one-half bag of mortar. Begin by placing two to three shovels of sand in a wheelbarrow, followed by the half bag of mortar. Use a mixing hoe to combine the dry components thoroughly. Once the sand and mortar are well-mixed, add the remaining sand gradually while continuing to blend the mixture. You want to achieve a consistency similar to that of cake batter.

It is essential to ensure the mortar is properly mixed to achieve consistent and reliable results. The correct consistency will allow the mortar to adhere properly to the cinder blocks, creating a solid bond. Take your time to mix the mortar thoroughly, ensuring all the dry ingredients are well-combined before adding water.

Once the mortar mixture resembles cake batter, gently add water and continue mixing until you achieve a smooth and spreadable consistency. Avoid adding too much water, as this can make the mortar too runny, impacting its adhesive properties. Striking the right balance is crucial for the success of your concrete block house construction.

By following this step and taking the time to mix the mortar properly, you will have a reliable and strong binding agent that will form the backbone of your concrete block walls. The properly mixed mortar will provide the necessary support and stability for your construction project. Let’s move forward to the next step and continue building your concrete block house.

Step 3: Constructing the corner walls

In Step 3 of building a concrete block house, we will focus on constructing the corner walls. The corner walls serve as the foundation upon which the rest of the structure will be built, providing stability and ensuring proper alignment.

To begin, arrange a few shovels of mortar on a corner board. This will act as the base for your corner walls. Make sure you have four reference points to work from and ensure that the walls are square to one another. Starting with the first corner, construct at least four corners up to a height of approximately five blocks.

Using a block trowel, spread the mortar mix in two thick lines, each as wide as the cinder block and extending far enough to lay three or four blocks in length. This will create a 90-degree angle at the corners. As you lay the first row of blocks, make sure to stagger the next block halfway over the bottom block. This “staggering” technique helps to strengthen the walls and ensures stability.

It is crucial to level and plumb the corner walls to ensure they are straight, square, and plumb. This can be achieved by using a level and a plumb bob. Pay close attention to each block’s alignment as you build the walls, making any necessary adjustments to ensure accuracy.

Smooth the mortar between the block joints using a thumb jointer tool. This will help create a clean and even finish, further enhancing the structural integrity of the corner walls. Taking the time to smooth the mortar joints will not only improve the aesthetic appeal but also enhance the overall durability of your concrete block house.

By following these steps, you will successfully construct the corner walls of your concrete block house. These corner walls act as a solid foundation for the rest of the construction, ensuring stability and alignment for the entire structure. Let’s move on to the next step and continue building your concrete block house.

Step 4: Running the courses

In Step 4 of building a concrete block house, we will focus on running the courses. The courses refer to the horizontal rows of blocks that make up the walls of the structure. Running the courses involves placing the blocks on top of each other in a systematic and level manner.

After completing approximately five blocks to construct the corner walls, it’s time to begin running the courses. Before starting, stretch a nylon string line around the line blocks and knot it off. This string line will act as a guide to ensure that the courses are straight and level.

Starting from the corners, fill in the first course by placing the blocks on top of the corners of the first row of blocks. As you continue, make sure to apply a generous amount of mortar between the blocks to create a strong bond. Use a trowel to spread and even out the mortar.

As you lay each block, press it firmly into the mortar, ensuring that it is level and aligned with the string line. Use a level to check the horizontal and vertical alignment of the blocks and make any necessary adjustments to maintain a straight and level wall.

Continue running the courses, checking the alignment and levelness after placing each block. It is essential to maintain consistent mortar thickness and joint size throughout the process. This will result in a visually appealing and structurally sound wall.

Remember to periodically check the alignment of the entire wall by using a level or a straightedge. This will help you identify and correct any deviations before proceeding further. Take your time during this step to ensure the precision and accuracy of the wall construction.

By diligently running the courses and paying attention to the alignment and levelness, you will progress steadily in building your concrete block house. The running courses will shape the walls of your structure, inching you closer to completing your project. Let’s now move on to the final step of building your concrete block house.

Step 5: Completing the walls
