That's a pretty big job where you first need to choose your materials. Here's a link with more information:
Here is some good information:
How large and how high of a retaining wall are you wanting to build?
Are you wanting to build it on a slope, or on a flat piece of land?
We did that just last year!!
Are you building something on top of the slope(like a deck or patio) or needing a retaining wall for planting?
I have 3 posts associated with how we were building a patio on a slope and we DIY'd the whole thing. I have ALL details in these posts starting it from scratch!!! We had to plan and build a retaining wall in order to do this:
-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 for the wall
-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
-the prep for the cement pad
This 3rd post you might not need depending what you are doing at the top of the slope. I will include it just in case you are adding a pad of some sort:
-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!!!
First you will need to decide on the material. It needs to be tied in and have sufficient drainage behind it as well. Drainage will involve gravel and pipe. This is much more complex than a quick answer here. Once you decide on the type of wall, re post your question for more specific tips. Also, add the terrain and soil type.
