Retaining Wall Components
Bunbury retaining walls components consist of concrete post and panels, all steel reinforced. The ‘H’ shaped posts are set into holes dug approximately 113cm apart. The depth of the holes must equal the height of the retaining wall required (max depth 1200mm). Walls up to 1.5m high can be constructed.
Equal pressures are then created above and below ground level (a cantilever effect). The posts are then aligned, levelled and anchored in a concrete footing. The panels are then inserted into and down the tracks of the posts. The bottom panels are supported by the footing around each post. Each panel interlocks and raises the height of the wall in 150mm increments.

Benefits of building a retaining wall
A retaining wall is a structure that not only serves a functional purpose but can also be pleasing to the eye. They can improve the look of a garden, as well as provide many benefits.
The primary advantage of building a retaining wall is to hold back soil and create usable space in areas with steep slopes or hillsides. Retaining walls not only increase the value of your property but they hold back dirt and rocks, prevent erosion and landslides, allow residents to use their land for activities like gardening or adding an outdoor patio area.

- 1) Set up a string line between two stakes positioned at each end of the required wall.
- 2) Dig the first two post holes to the depth and diameter indicated above, with centres 1.13m apart. (It is better to dig the holes too deep and add more sand than to dig too shallow and have to lift the post out to deepen the hole).
- 3) Place a post in the first hole, ensure it is at the correct height, and add the concrete footing. Check the post is vertical with a slight tilt towards the rear, as described in step 7. When the first post is positioned correctly adjust the string, using a string level, so that the height above the ground indicates the top of the wall and that it is aligned along the front and rear face of the wall.
- 4) Dig two or three more post holes as in step 2, and place the posts in the hole with the correct separation. Some installers insert the bottom panel at this stage, but the use of a measuring jig is generally better.
- 5) Add concrete for footings. One part cement to four parts sand is adequate for walls up to 0.90m high. higher walls require aggregate (blue metal) for stronger footings.
- 6) Lean the post slightly (2°) towards the load side for increased effectiveness, and ensure that the posts are in a line and that the tops of the posts are at the correct level.
- 7) Install the panels, making sure the top panels are flush with the top of each post. Brush the top of each panel to prevent particles of sand or grit from creating a gap between the panels. For a better finish insert thin wedges at the rear of each panel to force them forward before backfilling.
- 8) An effective method, particularly if intending to pave afterwards, is to keep the tops of footings below ground level and a brick to support each panel. This allows for easier adjustment of the panel heights and gives room for paving later.
- 9) Continue and complete the wall. This can be done in a number of stages if more convenient.
- 10) Where the wall is used to retain a garden bed, the use of plastic sheeting between the soil and the wall will help to prevent seepage of water and assist in the retention of moisture in the soil.
