I have an existing concrete area approx 10'x16' at the back of my carport. I want to install a sun shade/sail over it and have some questions on installing the posts I need.
- Can I use the existing concrete with either 4x4 or 6x6 post bases (something like the Simpson strong ties at Home Depot) with concrete anchors? Will this be strong enough? was thinking of using 10' long posts.
- If I go this route, do I need to attach the posts with some type of header beam to deal with potential diagonal forces?
- Or do I need dig new holes for the posts and use new footings?
