We just did this in the Fall actually.
I have 3 posts associated with a patio on a slope where we prepared for the cement slab and We DIY'd the whole thing.
Our planned cement slab was on a slope so we actually had to build a retaining wall to allow for the concrete. You may not need a retaining wall. If you don't, you could just go to my third post where we poured the cement. The 2nd post does have some prep for the pouring so you might want to look at that too.
I have ALL THE DETAILS (including the math) in these posts starting it from scratch!!!
-describes diagrams and sketches needed to build a retaining wall along with planning the wall and cement pad.
-laid out how to plan and diagram a retaining wall.
-math calculations to figure out how much stone and block to order
-how far we dug down and the cross section diagrams of what is going on under the ground
-What we did to build the retaining wall.
-what materials were needed.
-the actual building pictures
-prepping for the concrete pour
-how to order concrete
-how much concrete we would need based on math calculations that I give you.
-what materials we needed
-the process of pouring the cement
I hope this helps you, that is the exact reason why I wrote it! When you look at the posts, please feel free to comment with any questions. Good LUCK!!
Hi Lorie, I would advise hiring someone who knows how to do concrete forms, unless you know how to do it. You will also need to know how to "finish" the concrete once you get it poured, you can hire someone who knows how to do both.
I have attached a DIY video for you to watch, good luck!
