A. PLANNING 1. Check with your local council regarding any

compliance requirements. Where a large amount of earth is to be retained, it is recommended that an engineer be also consulted.

2. Draw up on paper the desired retaining wall. Where possible use readily available sleeper lengths to avoid having to cut sleepers.

B. WHAT YOU’LL NEED1. Make a list of the number and size of sleepers

required to cover the height of wall, also allow for the bottom sleeper to be embedded 100mm into the ground.

2. Make a list of the number and type of posts required (see diagrams A & C). The height of posts should be double the height of the retaining wall, meaning that half of the post should be below ground level.

3. In addition to the sleepers and posts, you will require quick-set concrete and the following tools: a) Shovel or post-hole digger; b) Tape measure; c) String line and level.

C. CONSTRUCTION1. Clear the area and mark out the line

of the wall using the string line.

2. Dig out a channel so that the bottom sleeper can be embedded 100mm into the ground.

3. Measure out and locate post positions. Dig the holes for the posts.

4. Starting at one end of the wall, insert the appropriate post and concrete into position ensuring that it is at the required height and vertically level.

5. Before moving onto the next post, place into position the intervening bottom sleeper. That will allow the next post to be better positioned. Using the string line and level ensure the post is horizontally and vertically level, then concrete into position. Repeat procedure for remaining posts.

TIPS• Moisture build up behind the wall can

be avoided by inserting an Ag Pipe and covered with blue metal prior to back fi lling.

• Seal sleeper cut ends with suitable timber preservative to resist rotting.
