So we just got a 10'×10' gazebo and put it up. it fits perfectly on our concrete slab that sticks out from the rest but unfortunately the other day it was blown over by high winds and i need to figure out how to secure it to the concrete. i just got some concrete anchors(screw type) and the correct bit for it. my only concern is that since the fame is pretty much flush with the edges of the slab that it will end up cracking the concrete. only 2 corners are completely flush with the concrete edge, the others sit on a larger section of the concrete. but the frame is made with a 1/2"×3/4" square tubing so the spots to secure it are only a 1/2" if that from the edge of the concrete i just dont know what kind of stress these anchors will put on the concrete.
