Alternative Permanent, Concrete-Free Foundations
Ground screws are a quick and sustainable alternative to concrete footings. They’re easy to install, even in tight spaces, and there’s no messy excavation or curing time. Once installed, they’re ready to take the full load straight away.
We install ground screw foundations for homes, businesses and renewable projects across Perth and Western Australia. From decks and sheds to solar farms, our ground screws deliver strength, speed and long-term stability. With a concrete-free system that reduces site disruption and lowers environmental impact, they are a smarter, more sustainable choice for modern foundations.
What Are Ground Screws?
Ground screws, sometimes called foundation screws, screw piles or earth screws, are galvanised steel piles screwed straight into the ground. They act as both footing and anchor, replacing concrete pads and working well in Perth’s reactive clays and coastal sands.
Each ground screw is designed so that structures can be securely fixed to it. Posts, frames, bearers or baseplates can be attached directly, creating a strong and stable connection. This makes the foundation system immediately ready to build on, with no curing time and minimal site disruption.
Benefits of Ground Screw Foundations
- Quick to install: No excavation or curing delays.
- Strong and reliable: Engineered for Perth’s residential and commercial projects
- Low disruption: No concrete trucks or wet trades needed.
- Eco-friendly: No cement, lower emissions, and every screw can be removed or reused.
- All-weather ready: Can be installed year-round.
- Tight-access friendly: Works in small or restricted sites.
Ground Screw Applications
Our ground screw systems provide permanent footing and foundation solutions across a wide range of projects:
- Underpinning and Foundation Support: Ground screws can be used to stabilise existing structures, providing a low-disruption alternative to traditional concrete underpinning methods.
- Decking: Fast, stable footings for timber or composite decks.
- Solar: Anchor frames securely across WA soils with minimal site disturbance.
- Tiny Homes and Cabins: Durable, relocatable foundations that suit low-impact living, whether in a Perth backyard or on a regional block.
- Home Extensions: Stable, concrete-free footings that minimise site disruption on Perth residential sites.
- Pergolas and Outdoor Structures: Secure bases for shade and garden features throughout Western Australia.
- Fencing and Retaining Walls: Reliable screw-in earth anchors for urban and regional WA conditions.
- Boardwalks and Walkways: Ideal for sandy or coastal areas across Perth and WA, with minimal disturbance to the environment.
- Temporary and Modular Structures: Reusable footing system for events and modular buildings

FAQ
How long do ground screw foundations last?
Our galvanised steel ground screws are designed for decades of service life and can be removed and reused if required.
Are ground screws better than concrete footings?
In many cases yes. They are faster, cleaner, and more adaptable to poor soils. They also avoid curing delays and are immediately load-bearing.
Are ground screws reliable?
Yes. Ground screws are proven to perform in Perth’s conditions. They handle heavy loads, can be installed in any weather, and cause far less disruption than concrete.
Do ground screws work in Perth soils?
Absolutely. Whether clay, sand, or limestone, our installation process adapts to Perth and wider WA soil conditions.
Can ground screws support houses, sheds, and extensions?
Yes. With engineering design, they can support substantial loads and provide permanent stability for residential and commercial structures.
Are ground screws eco-friendly?
Yes. They avoid excavation, concrete curing, and cement production, which lowers emissions. They can also be removed and reused, making them a sustainable choice.
How quickly can ground screws be installed?
Most residential jobs in Perth are completed in a single day. Once installed, the footings are immediately ready for construction.
Can existing structures be retrofitted with ground screws?
In some cases, yes. Ground screws can be installed alongside or beneath existing structures to provide additional support, depending on access and soil conditions.
