Browse Forums Landscape & Garden Design 1 Dec 05, 2011 4:03 pm I have a big drop off in my backyard, it is 15m across and is at least 2m high drop. I've had 3 quotes for retaining walls that require sleepers, I work in a hardware store so am getting the best price on materials but it still comes out to be over $4000 and is WAY too expensive. does anyone have any ideas? i'm in the country not near the city so don't have access to a lot of things. I was wondering about just sloping the land? but what about my timber fence? I've provided links to a couple of pictures.

If not, you will need one. Anything over 1m in height above ground requires it. You might be pricing up a way to do it that isn't suitable. Second, $4k is really cheap for that much wall. Is that just materials or does that include labor? What size sleepers are you planning to use? With that much height you'll need posts every 1.5m at a minimum and probably more like every 1m. You should be able to slop the ground and compact it at a 45° angle or less. IF you compact it well enough it won't move. Re: retaining wall help 5Dec 06, 2011 3:40 pm My council does not require an engineer if the walls are under 1m in height. We are having it in teirs (steps) 3 x 600 steps. I know that $4000 isn't that much and the reason is because i'm getting materials at cost and yes that does include labor, I have a friend who has an excavation business so am getting machinery at zero cost and cheap labor. I guess i'll just have to save a bit longer Re: retaining wall help 6Dec 07, 2011 9:16 am I don't see how you will get it cheaper if that includes labor. Make sure you allow enough depth from each step so that you don't over load the uprights. Re: retaining wall help 7Dec 10, 2011 3:02 pm thanks I've got someone (professional) doing it in January for me, that allows me a bit of time to save the money and the job will be done properly - i'll post after pics when it is done Re: retaining wall help 8Aug 04, 2012 10:21 pm Hi Wendlle, How's your backyard now? Did you slope it at btw? Would be interesting to see the final result since I'm having a slope backyard too and not sure what to do.... Thanks. Re: retaining wall help 9Mar 18, 2016 1:36 pm No doubt, Retaining wall is the best option to set up in this condition. I suggest gabion basket in Melbourne they could help you providing things in budget. Reference: http://www.gabionbasketsmelbourne.com.au/retaining-walls Thank you again Simeon.. I will call my certifier for that. Have a good day 4 5179 Thanks for your reply! All valid points and I agree with you on many of them. I am in QLD, any recommendations on a construction lawyer would be helpful 3 2637 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16142 |
