My 60 year old patio has cracked and broken on most of its expansions joints, and the two foot squares of concrete are sitting at angles that are real toe stubbers. There are 16 of them. I removed 16 more 30 years ago that were all leaning against the house at the wrong angle, funneling water toward the basement wall. Should I call a concrete leveling company or just replace the whole slab? What degree of angle should these be set at to funnel the surface and rainwater away from the house?

Hi all, I'm working on replacing a second story deck at the moment. I've read the DCA 6 decking guide cover to cover and I've found a few parts unclear. I'm getting ready to pour footings this weekend and I'm looking for a sanity check first. The section I'm confused about is Table 2 (joist spans and overhangs) and Figure 1A (joist span). The guide refers to L, Lj, and Lo, and I almost feel like L and Lj are backwards. With that said, I'll get to my question. I see a max allowable span of 14' for a 2x10 joist, and a max allowable overhang of 3' 5". I'm confused as to whether 14' is the max length of the entire joist (including overhang), or if this is the max length for the main span (from ledger to beam for example). The DCA 6 guide specifically says that Lj is the full length (including overhang) and that the Lj max is 14'. This seems to contradict what I've read elsewhere, which makes me think 14' is the max main span and you can extend it the length of the overhang past the beam. If that's not the case why cantilever in the first place. FWIW my deck plan is 20'x16', with the beam 13' out. Also, there is next to no code in my area and no permit required so I can't really consult with my local inspector. Thanks! MSal
