TetraWal & Fabricated Products

We custom manufacture components at our Geelong plant to suit the load requirements of any residential or civil infrastructure project. When manufacturing for land development projects our team often works with the project manager to deliver materials in lots, based on spreadsheet schedules, for ease of installation.

Galvanized steel components offer the long-term corrosion performance required for large scale projects. Steel sections are often designed to work with different grades of steel soldiers, to support varying height requirements within a project. Geelong Galvanizing provides a total service solution; cutting, fabricating, galvanizing and delivering product to site.

Engineering Considerations

We recommend engaging landscaping or engineering expertise to design and build your retaining walls. Drainage and wall structure needs to be considered to minimise erosion and withstand the weight of soil and water.

Infilling with retaining walls creates a level garden zone at a lower point on the slope by filling the area with material to raise a garden bed. While excavating can be used to create terraces by digging into the slope and using a retaining wall to hold back the soil. This can create sheltered zones on windy hillsides.

Based on the height of your retaining wall, council approval may be required, with engineer’s specifications for stability. Enquire with your local council for permit requirements.

The Galvanizers Association of Australia has released an Advisory Note for applications where Hot Dip Galvanized Steel is embedded in soil.

Residential Installations

TetraWal’s retaining wall solutions include all the hot dip galvanized steel posts you require to complete a DIY retaining wall installation. TetraWal components are available as H-sections for straight walls, 90º sections to build right angled walls, 45º sections to create softer angles and End Caps to finish your project. Choose from an extensive range of set lengths or create your own design.

Landscaping for Sloping Blocks

In Australia it’s estimated that around 60% of homes are built on sloping blocks. One of the biggest challenges for hillside homes is how to make the garden usable. Creating tiers is one option for blocks with limited space, while terracing creates flat, usable zones for garden beds and entertaining.

Erosion can be an ongoing problem in sloping gardens, creating soil and nutrient loss. Many sloping sites feature clay soils or sandy banks and plants can be over exposed to wind and sun. These gardens can experience soil slipping in the wet season or become unworkably hard in the summer.

One of the benefits of a sloping block is often uninterrupted views and with a little planning, landscaping with retaining walls can create terraced zones that enhance your outlook.

All TetraWal components are hot dip galvanized to AS/NZS4680 and are backed by a 5-year strength and corrosion warranty. TetraWal steel posts are designed to work with a wide range of retaining wall materials, from sleepers to stacked stone options.
