Retaining walls are an essential part of creating a level platform on sloping land. They are rigid walls designed and constructed to retain soil. Retaining walls prevent soil from moving or sliding, either because of erosion or the weight of the earth itself. They are commonly used in landscaping to support hillsides and prevent them from collapsing. They’re also used in construction to support the foundations of buildings built into hillsides.

We offer both new retaining wall installations and repairs service in Sydney. Most, retaining walls are built using concrete or treated pine sleepers. However, it is also possible to use other materials such as rock and gabion. The retaining wall that is right for your property will depend on several factors, including the slope of the land, the soil type, and your budget. A GJ Demolition and Landscaping specialist can advise you on the best solution for your needs.

Benefits of Retaining Walls

Retaining walls are structures that are designed to hold back soil or other materials and prevent erosion.

One of the main benefits of retaining walls is that they can help to stabilise the ground and prevent landslides. They can also be used to create more usable space on a property, such as by leveling out a steep slope and creating a flat area for a patio or garden. In addition, retaining walls can help:

Improving the look of your property: Retaining walls can create beautiful and functional features. They can also effectively cover up unsightly objects such as pipes and cables.
