HOLLOW BRICKS. Hollow concrete Bricks are concrete masonry units with combined benefits of both clay bricks and concrete blocks. They are produced in sizes similar to clay bricks thus are very light weight and easy to handle. On the virtue of their hollowness, they add to the heat and sound insulation along with reducing weight of the structure.
