Class A engineering bricks have a compressive strength greater than 125N/mm² and water absorption less than 4.5%.

What is the difference between cored and core bricks?

Bricks with core holes are also easier to manufacture since the heat from the firing more easily penetrates into the centre of the brick. This makes the brick stronger and quicker to produce. Lastly, there is cost. Since cored bricks use less material they are less costly to produce.
