Hi, all. I'm hoping I can get some advice and guidance on a patio upgrade I'm thinking of.
I currently have a wood patio that is roughly 12' x 20'. The wood is old (patio was built probably in 1960) and very worn, and it needs to be replaced. However, rather than put down another wood patio I'd like to have a concrete patio poured in. Here is the part I'm unsure of: the wood patio is 5.5" above the ground, and the patio itself is 4" below flush with the patio door. I'd like to bring up the new patio so it is flush (well, slightly below) with the sliding glass door, so we're talking about roughly 9.5" of poured concrete. My question, then, is whether I could have concrete poured to that height (depth?), and if it would be cost prohibitive to do so. Finally, are there other options I should consider? For example, I was thinking that if I couldn't do all concrete, should I replace the patio with concrete and then put pavers on top to make it flush? I would think that would be even more expensive.
I'm not planning on doing this myself, but before I start inquiring with contractors I wanted to increase my knowledge so I can make an informed decision whichever way I decide to go. So, besides advice and guidance on the approach I listed above, are there other resources available that will help to build my knowledge on this?
Thanks in advance for any help.
