6 Inch E-Interlock Bricks Without Groove Block

How are Interlocking Bricks made?
High quality interlocking bricks are made of cement, sand and Stone dust mixed together in appropriate proportions. The required materials are batched and mixed proportionately. Once the required mix is prepared, it is then compressed to form bricks with desirable interlocking patterns. The compression is achieved by using hydraulic compression system. The bricks are then subjected to curing for about 7 days.
