Ground screws outperform concrete footings in every way!
Designed for Australian conditions
With our wide range of screws available, we can accommodate nearly any project. Our selection includes various brackets, lengths, and sizes, allowing us to provide customised solutions for specific anchoring needs. We carefully assess load requirements, ground conditions, and the number of screws needed. Additionally, our diverse range of attachments for specialised installations gives you the flexibility to choose the perfect concrete free foundation for your next construction project.
GSA screws are the only ground screws designed and certified by Australian structural engineers to comply with the Building Code of Australia and revised Australian Standards AS 1170:2002, AS 2159:2009 and AS 4100:2020. Unlike other ground screws, all Ground Screws Australia products are manufactured from grade C350 steel, which far exceeds the ASI TN005 guidelines for designing to AS 4100.
Product Range
Our range of screw types has been designed to suit a variety of applications.

Applications
-
Do I need to have my ground screws installed by No More Digging?While we have installers based around Australia offering installation services, we also provide support to those of our licensed builders who wish to self-install. We sell/hire out drive attachments specifically to streamline the installation process and also provide support and guidance over the phone to overcome any issues which may come up during the installation.
-
Can ground screws be installed into rocky soil or rock?Yes, ground screws can be installed into any type of soil including rocky soil and even solid rock, with the help of pre-drilling equipment. We have developed a wide range of installation equipment including auger pre-drilling and DTH hammer drilling equipment to allow for installation in Australia’s hard and harsh soil conditions.
-
How long do ground screws last?In ideal soil conditions ground screws will last 100 years. When selecting a suitable ground screw we take the design life of the structure and soil/environmental factors into account. Our ground screws are manufactured from grade C350 steel and are hot-dip galvanised according to ISO 1461 which assist in corrosion protection. In highly corrosive soil conditions, the lifespan of our ground screws can be increased indefinitely through the use of sacrificial anodes.
-
What size Ground Screw do I need?The bearing capacity of a Ground Screw is determined by the bearing capacity of the soil into which it is installed (i.e the bearing capacity of one ground screw can vary significantly between two sites). Along with our engineers, we can assist in selecting a suitable ground screw size/model once we know soil conditions, design loads and details of the structure/project.
-
Do ground screws comply with Australian Standards?Our ground screws have been designed, tested and certified by Australian Structural Engineers to comply with Australian/New Zealand Standards and the Building Code of Australia. Just remember that not all ground screws are compliant with Australia’s regulations, so always make sure that you are purchasing from a supplier certified to the relevant Australian standards.
