While Wonder Walls can arrange for the installation of your retaining wall, if you choose to do it yourself, there are some things you need to know. Comprehensive step-by-step installation instructions are available on request.
Backfilling behind a wall can only be done once the postholes themselves have been backfilled for at least 19 hours.
Backfill is to be clean sand only. Backfill containing any other material i.e. rubble, stone, tree branches etc. is likely to cause damage to panels.
In all cases compaction must be only done in no more than layers of 300mm at a time.
Mechanically backfilling any closer than a distance equal to the height of the wall is not allowed unless the wall is adequately propped at the posts and at the centre of the panels during compaction.
A precast concrete post and panel retaining wall system is designed to hold up properly compacted earth. It is not able to hold up any surcharge loading without running the very real risk of damage that would later require remedial work.
Pay loaders, heavy machines or brick carters driving along the top of the backfilled wall.
Heavy loads being deposited immediately behind the wall e.g. pallets of bricks.
Use of the retaining wall as a base for constructing scaffolding or framework.
Fencers using the panels as leverage points when installing a fence.
Fence posts with concrete footings for the retaining wall need to have a cushion of sand between footings and the panels.
The retaining wall could be damaged should any of the above occur.
Finally, the concrete posts resting in properly compacted ground hold up this system of retaining. Drainers, in particular, must avoid undermining retaining walls when trenching or installing pipes.
The closer spacing of Wonder Walls posts allows for a stronger installation. It also results in lighter panels, more suitable for the DIY handyman.

Wonder Walls precast concrete panel and post retaining walls are 100% compliant with all the current and relevant Australian Standards – and these include:
Changes made include:
No changes were required to what are already extremely strong panels.
No – but a fence can be placed directly behind a Wonder Wall, and the distance required between the rear of the wall and a fence will vary depending on the type of fence being used, typically 100mm.
This includes a Colorbond fence.
The Wonder Walls system has been designed specifically as a retaining wall system. It is an engineered product capable of withstanding the various forces imposed on it by the earth that is being retained.
While it is true that some of our customers have in the past used Wonder Walls as a fence rather than a retaining wall, it is important to recognise that the system has not been designed to be a fence. For instance, the textured finish is on one side of the panel only – the rear of the panel is the side that should be holding back the earth.
