Product: Interlocking Bricks (update in 2013 posted at the end of this write up)
Interlocking bricks – as the name suggests locks itself with other bricks and it is these interlocks which give strength to the wall. No cement mixture is needed for the bonding.
This is a concept which many people of my State (Kerala) is not well aware of. People often tend to reject anything which is new. Same was the case with Interlocking bricks, as was evident by the response of people whom I approached to get expert opinion on the usage of these bricks.
It was my architect who introduced this concept to me. After visiting two or three houses built by the architect using these bricks, I decided that I was going to use this for construction.
