Thamks WB. So you are saying if I drill both sides of a 9" solid wall end with a wall starter kit ,and build a pillar around it will be fine.
Just wondering what to do with the foundation. If I am digging for wall foundation at a 1mtr depth around the wall,is it possible to put concrete at the same depth for the wall whose foundations are shallow (1930house). Will it reinforce the present wall,but a small section only.
