Interlocking bricks are made up of mixed sand, oil, and cement. The mixture formed out of these materials is compressed in a machine to manufacture bricks with an interlocking pattern. After this bricks are cured for a time span of seven days. This method reduces the costs compared to the bricks that are generally used for construction.
Interlocking bricks do not require any cement for binding just like regular bricks. But, there is a projection that stands out on one of the bricks which is created to fit into a depression on the brick next to it. On the other side, one part of the brick is formed to receive the projection of the brick on one side.
