Browse Forums Landscape & Garden Design 1 Jun 27, 2016 2:10 pm We have 1m high timber retaining wall, but it looks like it is not sufficient to stop soil coming to backyard. So we are planing to build another tiered retaining wall. From the current retaining wall and neighbor boundary, it is only 3m distance and 2m fall from top of current retaining wall. My question is how far back should we build new retaining wall and how deep post we need to dig. looks ok to me, round logs retaining walls are better than sleeper walls, more even preservative treatment and stronger since they include the whole tree and not just part… 1 2601 Thank you again Simeon..
