Ledger to Conrete Block

I am looking at attaching a ledger board for a deck to concrete block and am looking for the best method. Any ideas?

I have had good luck with lead concrete anchors.You can also use lag shields.These may be a bit stronger,but I am not sure.Good luck with you project:)

Are the block filled (poured full of concrete).....or hollow ......at the point where you will be attaching?

How wide is the deck (how far will it project from the block/house)? Any intermediate beams in the design to help support the weight of the deck and its contents (people, etc.) ? ...........or will the joists be supported only at the ledger and the rim? (Load-bearing capability is definitely a concern when choosing the type of fastening system to the concrete block.....as well as the frequency of those fasteners.)
