Ground screws can be used for a wide range of residential, modular and commercial applications, including new homes, extensions, decks, modular buildings and other structures. Suitability depends on the structural loads, soil conditions and individual project requirements.

Our ground screw system has documented structural design capacities for use in Australian building projects. For building applications, the foundation system is engineered for the individual project using information including the structure, design loads and site conditions, with the relevant engineering documentation provided for the project.

For an engineered foundation design, appropriate information about the site's soil conditions is required. If you already have a soil report, include it with your plans when requesting an estimate. If you don't have one yet, send us what you have and we can explain what will be required.

There isn't one standard ground screw for a particular type of building. The appropriate screw is determined by factors including structural loads, soil conditions and the project design. Our engineer uses the relevant project information to determine the appropriate ground screw type and size.

Ground screws can be installed in a range of ground conditions. Rocky or particularly hard ground may require pre-drilling or specialised installation methods. Suitability is assessed based on the site's ground conditions and engineering requirements.

Our ground screws are manufactured from C350 steel and hot-dip galvanised for corrosion protection. Required design life and site-specific soil conditions are considered when the foundation system is designed. Where more corrosive conditions exist, additional corrosion protection such as sacrificial anodes may be specified.

It depends on the project. Ground screws can reduce costs associated with excavation, spoil removal, concrete and construction time. On some projects this can result in significant efficiencies; on others, a different foundation system may be more appropriate. We assess the project rather than assuming ground screws are the best solution in every situation.

Ground screws don't require a concrete curing period. Once installation and the required checks are complete, the foundation can be ready for the next stage of construction. This can significantly shorten the foundation stage on suitable projects.

For suitable residential and modular projects, yes. Ground Screws Victoria can provide an integrated solution combining engineered ground screws with the Fenster & Panel SIP subfloor system, creating a coordinated pathway from foundation to floor.

For a preliminary estimate, send us your building plans, soil report, project location and any structural information or design loads you already have. If information is missing, that's okay — send us what you have and we'll identify what else is required.
