I am installing a 24' agp- my soil is on the sandy side. We have gone down to virgin soil and it seems well compacted. We will be installing 2"x8"x16" patio blocks at posts. I know this is site specific, but will this be ok for overall support at posts and under bottom rails? Also, I plan on using 1.5" insulation as a base- any thoughts on that?
