Browse Forums General Discussion 1 Dec 07, 2022 4:33 pm Hello! Trying to install fences next to a retaining wall and was wondering what others experience was? We have Agri pipe and rocks from the retaining wall on the way on where the fences are most suited to be placed. Moving the fences further with no obstructions will result to us losing a lot of unused space.. plus we already added concrete on the side of the house. Some recommendations are to crush the rocks and break part of the agri pipe. Just not keen on this option as I'm afraid it will affect the integrity of the retaining wall. We also don't have cleats on the retaining wall so we can't just install the fence on the retaining wall Developer initially agreed to add cleats but their contractor said that it will affect the integrity of the slab which is a risk they wont take. Not sure anymore on what to do. Has anyone got any experience?

Re: Retaining Wall and Fences 5Dec 08, 2022 12:52 pm As strannik has advised, you need to understand exactly where the boundary line of your property is. You will then know where the boundary is in relation to the wall. By the sounds of it (assuming you are on the high side of the wall) you are measuring your "1 metre of lost ground" from the front face of the wall back towards your house. Various retaining walls are built in such a way where a fence can be erected directly on top. Based on your photo, I'd suggest this wall is not suitable to do this. Short of removing the existing wall and replacing with a new wall that can have a fence built directly on top, then you most likely have no other option than to build your fence back from the wall so as to not affect the Agi drainage pipe. I'd strongly advise not to break the Agi Pipe of the existing wall as this will affect the drainage from behind the wall and could lead to premature failure of the wall in the future. Hope this helps. Re: Retaining Wall and Fences 6Dec 08, 2022 5:18 pm Thanks all. It's a corner lot, and the boundary is at the out corner of the retaining wall. If the developer added cleats before hand then no dramas but since they didn't and the retaining wall is 450mm. Then I have to install roughly 500mm after that wall to install the fence with no obstructions Would installing the fence on concrete pad be an alternative? ![]() As strannik has advised, you need to understand exactly where the boundary line of your property is.

Hope this helps. if the wall is owned by you, and money is not an issue (or space is worth more to you than money), i'd rip it up and install a different kind of the retaining wall that allows the fence to be put right on top of it. unless there are some estate/council design guidelines that mandate retaining wall to be like the current one. Re: Retaining Wall and Fences 8Dec 08, 2022 5:50 pm Unfortunately that was what the developer would do but apparently it will ruin the integrity of the slab.. not sure how legit the reason is. House is 2m away from the retaining wall but I don't know if it's worth to get a second opinion... ![]() ![]() Thanks all.

I'd definitely get a second opinion, cause it sounds like they just can't be bothered. If your slab is 2m away from the wall, I can't see how ripping the wall out and putting a new one in would cause any issues. It's not like you've got a several meters drop there that could collapse under it's own weight. On photos it looks like it's barely knee height. Our house is about two meters from the boundary as well and while it was being built the neighbor has cut his block by about 600mm. There was no retaining wall there for at least several months until our construction almost finished. It wasn't an issue at all. Re: Retaining Wall and Fences 10Dec 09, 2022 3:17 pm I agree, get a second opinion. Whomever you are speaking to is just being lazy. I'm on the low side of an existing retaining wall that was built right on my boundary line. I just had an 800mm high wall constructed for my build and engineering specs detailed I needed to come off the existing wall a distance of 1300mm so as to not undermine or affect the integrity of the exiting wall. 2 metres should be ample distance to remove and replace your wall without impacting your slab.

It has been 3 months since handover that we don't have fences cos of this issue. Will speak to our developer ! I'm in the same boat. Many many years ago the rear timber fence fell down & was replaced with colorbond. We have a 2nd fence falling down (3rd fence not far off). Pricing… 1 17704 ![]() That very much depends on location. In WA, for instance, the Developer would not be responsible for anything to do with fencing and it would be up to the person errecting… 7 8051 ![]() Thank you again Simeon.. I will call my certifier for that. Have a good day 4 31080 |
