Concrete retaining wall FAQ

A concrete retaining wall is a structure designed to hold back soil or other materials and prevent them from sliding or eroding.

There are several reasons why concrete retaining walls are often considered better than timber or stone retaining walls:

  • Durability: Concrete is a very durable material that can withstand the elements and last for many years with proper maintenance. Timber and stone, on the other hand, are more susceptible to rot, decay, and insect damage.
  • Strength: Concrete is a very strong material that can support heavy loads. This makes it an ideal choice for retaining walls that need to hold back large amounts of soil or other materials. Timber and stone are not as strong as concrete, and they may not be able to withstand the same amount of pressure.
  • Versatility: Concrete can be moulded into a variety of shapes and sizes, making it a versatile option for retaining walls. This customises concrete retaining walls to fit a project’s specific needs. Timber and stone are not as versatile as concrete, and they may not be able to be used in as many different applications.
  • Cost-effectiveness: Concrete retaining walls are often more cost-effective than timber or stone retaining walls. This is because concrete is a relatively inexpensive material and is easy to work with. Timber and stone, on the other hand, can be more expensive, difficult to work with, and have a shorter lifespan.
Concrete retaining walls are built by excavating a trench, pouring a concrete footing, and then building the wall on top of the footing. The wall is typically reinforced with steel rebar to give it strength.

The cost of a concrete retaining wall will vary depending on the size, and complexity of the wall and soil.

Concrete retaining walls are very durable and can last for many years with proper maintenance. However, the lifespan of a concrete retaining wall will depend on the quality of the materials used and the construction methods.

In most cases, you must obtain a permit from your local building department before you can build a concrete retaining wall. The permit process will vary from council to council, however, we ensure this is arranged for you as part of our installation service.

Yes! We specialise in complete yard transformations and can seamlessly integrate outdoor features like staircases, seating, and lighting into your retaining wall design. We own the machines necessary for various ground conditions, eliminating hidden hire fees, and have an on-site fabrication team for welding and custom work, including custom stairs.

Every project is different. Anywhere between 1 week and 2 months, depending on scope and size.

  • Challenging ground conditions:  Rocky terrain or unstable soil can complicate excavation and require specialized equipment or techniques, increasing costs.
  • Landscaping: Enhancing the area around your retaining wall with plants, pathways, or other features will add to the overall project cost.
  • Fencing: If you plan to install fencing on top of or around your retaining wall, factor in the cost of materials and labor.
  • Reestablishment of grass:  Access for construction equipment may damage your lawn, and you’ll need to budget for replanting or laying new turf.

There is no height limit, however maximum height is around 4m.

Piers drilled into natural earth and concrete are used to reinforce the foundation. Steel columns may also be used for additional support.

  • subsiding of ground around area
  • wood rot
