Is your backyard built on a slope? Level it out by building a retaining wall and maximising your space.
While building a retaining wall sounds like a big job, this cost effective, light weight option will make it an easy backyard fix. The one thing to keep in mind is council approval. If your proposed wall is 600mm tall or closer than 900mm to your boundary you will need to advise your local council.
- After digging out your area, mark where your wall and support posts will be positioned. The spacing between posts will depend on the length of the timber you decide to use and the amount of space you have to retain.
- Put the posts in the place and fill the holes with concrete, this will provide the wall with a good secure foundation.
- As a rule of thumb, you will need one third the height of the wall in the ground with two thirds out of the ground. You can then attach your sleepers.
- The secret to a successful retaining wall is drainage. If you don't allow any drainage options, water can build up behind it and push it over.
- Once you have installed the sleepers and drainage, you can replace the soil that was removed.
