I need expert advice here please, I intend building a 3 bedrooms flat using 6' machine moulded blocks that I supervised the materials and moulding process. 40 hollowed 6' blocks were moulded per one bag of cement. I intend using 9' hollowed blocks for the foundation with reinforced pillars/columns.

Thanks in anticipation.
