You should always run your ag pipe into a silt pit (300mm should suit) before connecting to existing storm water system. You should also look at an aggi pipe behind the wall and some form of waterproofing and drainage aggregate to protect the wall. I would use galvanised steel posts. Hope this helps a little. Please feel free to ask any questions. Re: DIY my backyard 7Jun 07, 2016 2:20 pm Hi Rispar, Any sort of retaining wall will suffice as long as it is constructed properly. Not sure if you are looking at link walls or besser/concrete blocks but both have positive and negatives as well as different costs. The link block walls are very easy to install, don't need a concrete footing in most situations and are permeable. Besser block walls require re-inforced footing, steel work, are harder to lay and will require render or some sort of coating to look decent as well as filling the internal with concrete. Treated pine timber retaining walls with galvanized posts are the easiest and most cost effective. I always sand the sleepers and bevel the edges then stain them which looks better than just installing the sleepers as is. DIY, Home Maintenance & Repair That laser level looks lovely!
