Hi chaps, I feel slightly out of my depth here, so I’m hoping you can help. These fence posts are attached to the single skin brick wall with three big coach bolts. The corner posts have an extra bolt at 90 degrees. The wall’s about 3’ high, the posts are 10’. I think I would like to cast concrete around the bottom of the posts. The wall is sturdy, but once the trellis is attached to the tops of the posts, the whole thing is going to be quite top-heavy. So, a couple of questions - how deep do I surround them with concrete OR should I make a foundation out of concrete and then brick round the posts? What should I make the shuttering/form out of, and how sturdy does it need to be? Do I need to line the shuttering with anything? How long do I leave it on? In terms of making the concrete - 1part cement to 4 parts ballast, yes? Do I need to worry about anything? Sorry for all the noddy questions, but this is far beyond my usual playing-in-the-garden. LS
