I need to build a retaining wall only abut 12 inches high about 6 feet out from my foundation. I have read in an article that you should start the first layer of blocks about 2/3 buried under the top soil. However, it did not say why and I have yet to understand why it is a necessary staep. My wall will only be a max of 2 blocks tall. The only reason I can think of is that it may help stabilize the wall, but it still doesn't make sense. It seems the only part stabilized would be the part below ground (the 1st layer)?? So is it simply for aesthetics or is there a structural purpose to doing this. Also, the area to build mine is flat already so I may need to tap the soil a bit to keep the wall straight but otherwise its a flat surface to begin with. Perhaps that is why they say to dig also...in order to create a flat surface??? Answers will be much appreciated...Thanks!
