Hi I'm installing a 12X14 wood Gazebo on an exiting concrete slab that measure aprox 12x 40. However, based on the space alotment for the Gazebo roof. the footing in the front will overlap my concrete slab by .6 inches. Can this be balanced or better supported by simply sliding concrete paving stones under those two footing? Or do I need to figure out how to poor concrete at the base of the two footing?
Thanks in advance for your advice,
Enclosed a picture of the gazebo being installed for reference.
