With the advance of several methods and developments in the construction field, new construction materials and equipment are deployed to improve the excellence of work. Interlocking bricks are the improved version of the traditional bricks. They are made up of clay or cement and are slightly different in shape and structure. Interlocking bricks are manufactured in such a unique way that each brick gets locked itself with another brick using a shear key and lock mechanism. These bricks can be laid one after another without using any mortar or binding material. http://www.txlsk.com/interlocking-blocks/
