Is Interlocking Brick Good for Construction?

What are interlocking bricks and is it worth using them for construction? Is it safe to use them, or do they come with structural disadvantages? This article will discuss what interlocking bricks are, the advantages and disadvantages of using them and whether they are good for construction.

Interlocking bricks can be a good solution for residential buildings in hot climate areas that are prone to earthquakes. They are also suitable for driveways. Interlocking bricks can help you cut costs by as much as 35%. However, they do not work for buildings over two stories in height.

Interlocking Bricks Explained

Interlocking bricks are created by mixing sand, soil, and cement. This mixture is then compressed in a machine to produce bricks with an interlocking pattern. After this is done, the bricks are cured for seven days. This can often come with reduced costs compared to creating regular bricks.

Interlocking bricks do not use cement to bind together like normal bricks. Instead, there is a projection that sticks out on one side of a brick, which is designed to fit into a depression on the brick next to it. On the other side of the brick, there is a depression that is designed to receive the projection of the brick on its other side.

Advantages of Interlocking Bricks

There are several reasons you might want to use interlocking brick. Let’s first go over the pros of interlocking bricks:

They are cheaper to make. Since interlocking bricks are made with sand and soil in addition to cement, they come with lower costs than regular bricks that are made entirely with cement. In fact, interlocking bricks can cost as much as 35% less than regular bricks. Interlocking bricks can have as little as 10% cement, with the rest of the mixture consisting of sand and soil.
Interlocking bricks are more resistant to earthquakes. The reason for this is simple: Regular bricks rely on mortar for their support system. When the mortar fails, the entire wall or building will fail. However, interlocking bricks have their own support system that does not rely on the mortar. They support each other effectively.
They are recommended by some governments. Interlocking bricks are recommended by some governments in areas where earthquakes are common. If you are trying to build a building in an area prone to earthquakes, interlocking bricks might be a better choice.
They provide better insulation in hot areas. Also, interlocking bricks are great for hot areas. Since they are compressed, there is more mass, and the bricks keep the interior of the building cooler.
They are environmentally friendly. Using interlocking brick can help preserve the environment. Not only will you be using less concrete and mortar, but residents of buildings will not need to use air conditioning as much due to the cooler internal temperatures.
They address the labor shortage. Not only does it cost less to create interlocking brick, but less effort and fewer workers are needed as well. For example, compared to standard bricks, there is no need to check the water level.
It is quicker. If you want to create a building quickly, using interlocking brick will help you do so. You won’t have to cure the bricks as long (you only have to cure them for seven days compared to 2 days).
They are durable and need less maintenance. Interlocking bricks are strong and durable. They also require less maintenance than standard bricks.
They are easier to recover. If you decide to dismantle the structure later, it is easier to recover the bricks without damaging them if you used interlocking bricks. However, if you used mortar, this will be more difficult.

Disadvantages of Interlocking Bricks

However, using interlocking brick definitely comes with its disadvantages as well. Here are some of the cons involved in the usage of interlocking brick:

Wear and tear. Unlike regular bricks, interlocking bricks are not usually plastered over. On the one hand, this can save you some money and time upfront and result in more visible wear and tear. The reason plastering is not used is because interlocking bricks are made with exterior designs already.
Less resistant to extreme weather. Since plastering is not used, interlocking bricks are less resistant to extreme weather conditions, including heavy rain. In fact, they are more likely to leak and get water damage compared to regular bricks.
Less resistant to infestation. For the same reason, interlocking bricks are less resistant to insect infestation. Plastering is an important buffer that protects against insect infestation.
Not for tall buildings. Interlocking bricks are not safe for tall buildings. In fact, they are only good for the first three stories of a building. That is why interlocking bricks are usually reserved for residential buildings and are not used to construct commercial buildings.
Not very popular. Interlocking bricks are not very common. Standard bricks have remained unchanged for a long time. According to most people’s reasoning, if it is not broken, why fix it?

Are Interlocking Bricks Safe?

Is it safe to use interlocking brick? It depends. As mentioned, it is not safe to use them for more than three stories. Even using them for a third story is pushing it. Ideally, interlocking bricks should not be used for structures that have more than two stories.

On the other hand, if you are building a small structure in an area prone to earthquakes, using interlocking brick is actually safer for the reasons mentioned earlier in this article.

Interlocking Bricks for Driveways

Until now, we have discussed using interlocking brick for vertical structures. However, interlocking bricks are more commonly used for horizontal surfaces, such as driveways.

There are several benefits of using interlocking bricks to pave your driveway. They are more stylish and look better, with more beautiful and varied designs. It is easy to repair or replace them, and you also won’t have to worry about the integrity of the structure like you would if you were building a vertical structure.

Using interlocking brick with beautiful designs for your driveway can help you improve your house’s curb appeal, potentially increasing the value of your property.

Is It Worth Using Interlocking Brick?

If you are looking to build a structure as quickly as possible and as cheap as possible, it is worth using interlocking brick. This is especially true if you are building a residential building in an area prone to earthquakes.

On the other hand, if you are building a commercial building or trying to create a more resistant structure to extreme weather and insect infestation, you should not be using interlocking bricks.

Conclusion

At the end of the day, whether interlocking bricks are good for construction or not depends on your needs and goals. If you need to save money to build a residential building in an area where earthquakes are common, they could be a good choice.

On the other hand, if you live in a more moderate or a colder climate where earthquakes are uncommon or rare, then fired bricks are probably going to be your best option. While they cost a bit more, they provide better resistance to rain and protenction from the elements.
