I ended up spending under $6K, inclusive of drainage aggregate and built the entire wall myself out of Tasman Blocks (you fill the core of the Tasman blocks with 20mm blue metal) on a concrete footing. I did not use the no-fines concrete method behind the wall. I opted for a filter fabric barrier between the backfilled soil and a 250mm wide layer of blue metal up the back of the blocks. (100mm Ag pipe at the base of course) The combined total of blue metal used for core filling the blocks and behind the wall was approx 9 tonne. (sounds a lot but it really isn't) goto page 31 of my build thread to see some pics of the wall in the early stages. viewtopic.php?f=31&t=12911&hilit=memphis&start=600 Re: What type of retaining wall? 10Dec 22, 2010 5:14 pm keen That is a very nice job, KID. I like the concrete kerb in front of the first course, finishes it off nicely. I did that for 2 reasons. I wanted to lock the bottom course in (not really necessary but that's just me) and I also wanted a really easy mowing strip.

Does everyone get fairly detailed specs like these during quotations for their ret. walls? If yes, we should re-evaluate our approach to tradies and quotation process My signature is distracting people from my wise posts ...

A feature that is practical, ads strength and looks good - that's good design right there I reckon! Have you got pics of the finished job now with vegetation re-instated etc ? As for your comment about taking so long on one job, - there is no such thing as a short cut in building, and what else could you be doing, sitting on the couch? Cant beat the satisfaction from a job done right that has saved a lot of money. Only the best contractor would have done as good a job and it would not have been the lowest quote! To get back on topic (sorry Davidj), I think the Tasman blocks are a great alternative if done well like KID, and I have seen a wall built to about 3m out of them (in good drainage sand though). Check the manufacturers specs and overbuid, overbuild, overbuild & and overdrain, overdrain, overdrain !! (Well I would). Good design is the key, plan, plan, plan, what I do is draw everything (CAD), - if I can draw it I know I can build it and how to go about it. It's good fun too! In relation to the timber & steel walls, steel in the ground will rot away eventually as well, unless it is 316 stainless.

A feature that is practical, ads strength and looks good - that's good design right there I reckon! 2 "must follow" golden rules, correct drainage and with any dry stack wall like Tasman, the bottom course needs to be dead on level. Any issues with the bottom course will be reflected in every subsequent course(s). What and how you choose to construct your wall comes down to a number of factors such budget or the finished look you want or your materials and method may be governed by engineering requirements to satisfy Council Regs. Do your research - continue to ask questions as you have until you are happy with the approach you choose to take. Quote: Have you got pics of the finished job now with vegetation re-instated etc ? Sort of - I have not finished the council verge area yet as that's where I land all of my materials and will be done last. (I have the back yard to do yet) Sorry, I'll stop hijacking this now Before - http://i459.photobucket.com/albums/qq311/EB_Photos_2009/IMG_1703a.jpg After - Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: What type of retaining wall? 15Feb 10, 2011 8:16 am davidj very nice wall there. Am starting to consider brick 'blocks' and then rendered for the front yard. Any comments on these re-price, and maybe even some picies? Prices per block vary so I would ring around to get the best price. Depending on the amount of blocks you need will determine how much per block and delivery charges etc. Her is a pic taken this morning of my completed wall.

I get lots of run off that would be going towards the wall, but I plan to install good drainage. This would place lots of presure on the wall, and I don't really want the bricks to start moving or falling over after a few years!

A standard 390mm Tasman block like the ones I have used weigh in excess of 15kg each and are designed to be core filled with aggregate which makes them even heavier. My wall has not moved 1 mm from the time it has been constructed and its got just under 1 metre of drainage grave and fill behind it. My wall caps are just sitting on top and are not fixed in place with any type of glue or liquid nails. Effective drainage is the key to any retaining wall. Most walls fail due to the backfill swelling when it gets wet because the drainage is not done correctly. Thank you again Simeon.. I will call my certifier for that. Have a good day 4 5179 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16121 Hi All, I engaged a tradie to install concrete retaining wall 600-800mm high over 32 meters in Victoria.
