Any advice on what type of bolt would be best to use in my case?
I am erecting a pergola over my koi pond and attaching 4x4 posts to the corners of the pond wall, using post shoes.
The wall is concrete blocks laid on side, topped with a very hard dense type concrete coping.
I cant attach straight to the coping stone as the weight would probably rip them off ina strong wind.
I want to go through the coping stone, through the small layer of mortar into the concrete block (dense block)
I have looked at using anchor bolts and going straight through, but I have also seen sleeve bolts. Not sure which would be best to use as I know drilling into a dense block, you usually dont end up awitha perfect hole.
Any other ideas would be helpful!
