A retaining wall is a structure that’s built to support soil that would otherwise not be supported. Retaining walls are created to give structure to a sloping garden, to create terracing and to assist with drainage issues. Because retaining walls are structural, they can pose a danger from collapse if they are not properly constructed. Therefore, they often require approval and certification from the local council before you can build one. In fact, you may need to hire a professional to design and certify your plans in order to get approval. So, what is the process for getting approval for retaining walls?
Types of Retaining Walls
The type of wall you choose may impact on the approval process. The 4 main types are:
- Stone retaining walls
- Concrete retaining walls
- Timber retaining wall
- Gabion retaining walls
Stone Retaining Walls
Stone retaining walls are incredibly strong, durable and beautiful to look at. Rock or stone is often chosen where the demands of the wall to retain large areas of soil are greatest.
Concrete Retaining Walls
Concrete walls can be built quickly and provide good strength and durability. They’re usually made by pouring concrete into a mould or with Besser blocks.
Timber Retaining Walls
Timber sleepers made of treated pine or hardwood are commonly used. Also, treated pine is the most economical choice but also the least durable.
Gabion Retaining Walls
A gabion retaining wall consists of stacked rocks or stones inside metal cages. Each metal mesh basket is held together with wire.
How do you get Council Approval for Retaining Walls?
Basically, council permission will be required if your retaining wall poses a danger to yourself or the public. Generally, this applies to any wall that’s over a metre high or if it’s near to a boundary or another structure. So, check out the Coffs Harbour council website for the approval process.
