Interlocking bricks, types, and size details

Interlocking bricks are a type of building material that is designed to fit together like puzzle pieces without the need for mortar or cement. These bricks have special shapes and grooves that allow them to interlock with one another, creating a strong and stable structure.

Interlocking bricks are typically made from cement, soil, or a combination of the two, and are molded into specific shapes using a machine. 

The bricks are then allowed to dry and harden before they are stacked and interlocked to create a wall or structure.

Life span of Interlocking bricks

The lifespan of interlocking bricks varies depending on the type of material used in their production. Generally, interlocking bricks can last anywhere from 10 to 50 years. However, it’s important to note that bricks made from mud or clay tend to have a shorter lifespan than other materials.

On average, interlocking bricks made from durable materials such as stabilized soil blocks, cement, or concrete can last up to 40 or 50 years. Conversely, interlocking bricks made from mud or clay may only last around 10 years due to their susceptibility to erosion and other environmental factors.

Advantages of Interlocking bricks
