Over the last few months I've cut down and removed 30 palms from a small section of my front yard (I now have ocean views!!!), and now I need to build a retaining wall on the boundary so that I can make that part of my yard useable. I've built walls in the past from treated pine sleepers, concrete sleepers with gal posts, sandstone quarry logs and a couple of other methods. However I'm looking for a super cheap method, I've heard of stacking and filling old tyres, has anyone tried this? It'll be about 20m long and 1.5m high, my neighbour will be planting a hedge in front of it so it doesn't matter what it looks like.
P.S don't stress about the palms, I have another 90 spread over my property
I understand you're thinking about something "super-cheap", but you still might be interested in these previous retaining wall discussions on Workshop:
Good luck with the project. I hope Workshop members will be able to assist.
I had a look through the gabion discussion, this might be the way to go. I have a few contacts for sandstone ballast that are pretty cheap. I'll do some estimating and see what I can get the square metre rate down to. The big saving with these is that there's no piers in the footing like there is with timber walls.
Coincidentally I found a page about tyre retaining walls. They won't do for the height of wall I'm working with here.
Thanks again, Roy
@royqtry post and rail
It will also require Certified Engineering Details submitted to your local Council
I've started costing things up and I am finding that the pine sleeper post and rail wall will be marginally cheaper than gabions. Still not sure though, gabions seem a lot easier.
I was wondering about the engineering and approval side of things, how high can you go with a wall without needing council approval? In the past I have only ever replaced existing walls so the engineering had to be done but we didn't worry about council approval.
@royqI have all the engineering & construction data used in costings, unfortunately it had to be Blurred..for Professional & Other reasons. Regarding Gabion Walls Labour & Placment on your Sloping block would be very expensive even tho the cage and fill may be cheap.. do the sum$
But if you need some additional info (other than photos) PM me or send me an email appsb4Ubuild
Some Councils want an engineers certification for Boundary retaining walls higher than 1m? so please check with your councils website Under
Building Approvals->checklists-> retaining walls
Thanks @BIM_Engineer, You're spot on, I just looked it up. I might be able to put a 600mm wall on the boundary and then a 1m one set back from the boundary to get around it. What do you think?
I'll be doing all the filling myself to keep $ to a minimum so it'll just be materials that I have to take into account.
Terracing logic ...Sounds good to me
You will need to set back 1.2 (min.) x the walls height for each terrace. hth
@BIM_Engineer thanks for your help! I won't be building the wall for a few months but I'll keep you updated.
