Planning on building a pergola over our concrete patio and anchoring the posts to the concrete. Just got the patio extended and 3 corners have 6" footings the fourth corner will be on the original slab that is 4" thick. Planning on anchoring the 6x6 posts using a Strong Tie post base but am concerned about not having 6" footings on all corners. Any suggestions?
