Hey all !!!!!
We have a new house in a new development and sadly there is no trees. I'm looking to install a Pergola that has 4 poles 15 ft square. My question is, what size posts do I use and how deep should I place them underground? My whole family love to hammock camp and we want to be able to hang with all 5 of us on it. Thats why i'm setting the posts at 15' square.
Any suggestions would be greatly appreciated.
