Browse Forums Landscape & Garden Design 1 Dec 13, 2011 10:58 am Good morning. I'm embarking on my first sleeper retaining wall. After purchasing a pile of standard sleepers, I've realised I need to create several 45-degree corners and am not sure how to accommodate attachment of the horizontal sleepers at that angle to a right-angle-edged post. Do I need to buy specially cut posts, or can I still use the right-angle posts? And if the latter, then how? Thanks in advance for any wisdom that comes this way!

As for the H-brackets, they look like a simple solution but the price is prohibitive. I really need to do the best I can with timber posts. Thanks. More options welcome... Re: Help please: 45-degree corners on timber retaining walls 5Dec 13, 2011 3:17 pm I sketched that up using Google Sketchup, for indicative purposes only. If the wall is greater than 1.0m high I would recommend engaging an engineer. If it is less I would recommend using sleepers and place the posts at at least third points along the length and bury the verticals to a depth of at least the height of the wall and set in place with rapid set concrete poured into the hole followed by water.

Unless they are 200mm x 100mm they will be too thin to be effective as posts. Room4acubby mentioned an engineer. You will need an Engineer if your wall is over 1m in height above ground. The spacing of your posts will relate to the length of your sleepers and the height of the wall + what you intend on retaining. with a little more info more advice may be available. How long is the wall? How high is the wall? What is on the high side of the wall? How far away? Is the ground flat behind it, or does it slope toward/away from the wall? What is on the low side of the wall? How far away? Is the ground flat infront of it, or does it slope toward/away from the wall? 6 7974 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 2283 Engineering timber is certainly a less fuss option, times cheaper to supply and install and better withstands humidity. 1 11522 |
