Here's another of those how to things. Or at least my spin on it.
Ground at the back of the house was cut to build our extension. Need to retain airflow under the house and keep the grass area functional. And the lovely wife wants to plant flowers and crap at the back of the house. I also have this lovely plumbing inspection point thats poking out of the ground like something on a wedding night. So...the plan, make it look nicer.
I also have an existing small wall that runs along the back side of the house, so I need to hook into this also.
1. Clear area. Measure to see where wall needs to go. And what height it needs to be. Look around for cheap sleepers, the ones I got, $10 each for redgum. Yay me!
2. Made the first edge to figure out total lengths and distance from house. Concrete in place.
3. Sleepers are 2.44m long, dig some holes roughly that far apart.
4. Made another piece for the other end, where it hooks into existing wall. Had to dig out behind existing to unbolt and cut shorter so I could put new sleepers in. Glad I put plastic behind the old wall, bolts undid with no fuss whatsoever, just some surface rust on them. Concreted and screwed into place.
5. String line helps get the posts in the right place. A level is essential as well. I Drew a line in the centre of the posts and at 2.44m intervals on the string (after it was tight) This way, line up the post with the mark on the string. Concrete posts in place and brace while concrete goes off.
6. Predrill ends of sleepers so drilling and screwing them in place is a little easier. Chock the sleepers in place, drill then screw. I used 75mm long galvanised batten screws, sunk the heads about 20mm so I get good penetration into both parts.
7. First pair in place, nice and secure
8. Second pair done. Had to dig into the dirt wall for drill access when drilling and screwing. Digging never stops
9. Last pair done, cut to length and dropped into place.
10. Made a cover for the stink pipe if ever anyone needs to get to it. It just sits on top.
11. The finished product. Dirt turned and compost mulch stuff added and dug through. Prior to back filling, I nailed black plastic onto the wall to stop moisture seepeage into the timber. I also oiled the finished wall to keep the colour looking nice and protect the timber a bit from drying oout.
So there you go.....simple.......

Sorry, you need to put photos and more information up, Concrete paths aren't retaining walls? The better the info, the better the reply and the more chance it will help others
