Interlocking Building Technology

On the Tuesday weekly meeting at Hidco, I talked about the technology that I'd come across in a seminar in Delhi that'd been organised by MoHUPA. It uses grooved bricks; walls can be made by interlocking these special bricks without use of mortars. I correlated this with the interlocking paver bricks that we use all over Kolkata. I requested the technical team of Hidco to see if roadside public toilets, boundary walls, police kiosks etc could first be started using this technology. Here is a picture from the material that was given to us in Delhi:
