dannyboy123 Posted October 29, 2019 Posted October 29, 2019 What height limitation is there for a 100mm single wall that is used as a retaining wall? The height I'm looking at is 420mm. I could turn the stone around and have a 140mm thick single leaf wall but the height would then be 500mm. Is this ok?
Declan52 Posted October 29, 2019 Posted October 29, 2019 It all depends on what it's holding back. 420mm won't work with standard blocks, it will have to be 450mm. You could build the first course 225mm wide then step it in so it's 100mm wide for the 2nd course.
