I am going to erect a fence out of steel and brick. The posts are going to be made of brick . The dimensions of each brick post will be 16 inches square running to a height of 6 feet. I am required to drill out and put a piling at each fence post . I will be using rebar and concrete for these pilings. Soil conditions are 12-18" top soil with poplar tree roots and then clay.
Question I have is how deep should I go with the pilings and what diameter would be required? I hope I gave enough information....Jim
