Best way to attach low level deck to existing concrete slab.
I am wanting to build a two level deck this spring. The first level will sit on top of a 10' x 12' slab of existing concrete that is 6 inches thick. I have about 12 inches between our back door base and the concrete slab to work with, so i am planning on making the first deck level 10.5 inches in height in total. I am hung up on the best way to build and attach the first level. 10.5 inches seems to small to try and attach posts with beams and joists. And if I don't use posts, then what is the best way to attach the deck to the slab? Any suggestions would be greatly appreciated. Thanks
