Why Concrete-Free Foundations?
Concrete footings have long been the industry standard, but they are not always the best choice when considering that concrete is slow, messy and carbon heavy. In Perth’s reactive clays, sandy soils and limestone conditions, modern alternatives like Ground Screws, screw piles and Hexplates often deliver faster, cleaner and more sustainable results.
Concrete-free foundations mean:
- No curing delays, ready to build immediately.
- Minimal excavation and site disturbance.
- Eco-friendly alternatives.
- Adaptability in tight access or sensitive environments.
- Proven structural strength for residential, commercial and engineering projects.
Our Concrete-Free Foundation Technologies
Continuous flight steel piles driven directly into the soil to create strong, immediate load-bearing bases. These are perfect for transportable buildings, decks, sheds, solar panel bases, building extensions, fencing and underpinning. Ground screws can be installed relatively quickly in tight spaces with minimal disruption.
AGS’s own modular steel plate footing system, designed as a permanent, concrete–free alternative. Installed with a jackhammer, Hexplates spread loads evenly across soils and can be used for decks, boardwalks, walkways, retaining walls and commercial builds. Relocatable, reusable and highly eco-friendly.
When existing foundations show signs of movement, concrete-free underpinning stabilises and restores strength. Using ground screws, screw piles or injection techniques, we reinforce homes and buildings with minimal excavation and disruption.
Applications for Concrete-Free Foundations
Our solutions are trusted across Perth and WA for:
- New home extensions and renovations.
- Portable buildings.
- Modular homes, granny flats and structures.
- Decks, patios, sheds and garden structures.
- Solar and renewable installations.
- Solar and renewable Walkways and boardwalks. .
- Retaining walls and fencing.
- Commercial and industrial builds.
- Foundation underpinning and repair projects.
Eco-Friendly Foundation Alternatives
Concrete production is one of the world’s largest industrial carbon emitters, releasing around 930kg of CO₂ for every tonne of cement produced. By moving away from concrete footings, our systems cut emissions dramatically while also reducing waste, noise and ground disturbance.
Ground screws, screw piles and Hexplates require minimal excavation and no concrete trucks, which means less soil is displaced and the surrounding environment is preserved. Because they can be removed, relocated and reused, these systems leave almost no permanent trace when taken out, unlike concrete pads that must be broken up and sent to landfill.
This low-impact approach makes concrete-free foundations particularly well suited for heritage sites, sensitive landscapes and urban infill projects. Where preserving existing structures, landscaping or archaeological layers is important, our solutions provide a stable footing without the heavy machinery or destructive excavation associated with concrete.
By choosing concrete-free foundations, you are not only reducing your project’s carbon footprint but also protecting the integrity of the environment and surrounding site for the long term.
Applications for Homes
Hexplates are not just practical, they are part of the future of eco conscious building. They require minimal excavation, meaning your landscaping stays intact, and they create stable, concrete-free footings that support decks, extensions, sheds and even full foundations.
They are also a great sustainability story. Hexplates are reusable, recyclable and produce far less carbon pollution than concrete. For homeowners, that means confidence in both performance and environmental impact.

FAQ
What are concrete-free foundations?
Concrete-free foundations use alternatives such as ground screws, screw piles and Hexplates to provide strong, stable bases without the need for concrete pads or slabs.
What are the benefits compared to concrete footings?
They are faster to install, ready for immediate use, more eco-friendly, and cause minimal site disturbance. They are also removable and reusable, reducing waste and long-term environmental impact.
Are concrete-free foundations as strong as concrete?
Yes. With engineering design, ground screws, screw piles and Hexplates can match or exceed the performance of traditional concrete footings.
Can they be used in Perth soils?
Absolutely. Our systems are designed for Perth’s reactive clays, sandy coastal soils and limestone conditions, giving reliable performance across WA.
Are they permanent or temporary?
They can be used for both. Ground screws, screw piles and Hexplates can be removed, relocated or reused, making them flexible for temporary or permanent structures.
Are concrete-free foundations suitable for heritage sites?
Yes. Because they require minimal excavation, no heavy machinery and no large-scale disturbance, they are well suited to heritage and environmentally sensitive sites. They provide stable support while preserving landscaping, archaeological layers and nearby structures.
How much do concrete-free foundations cost?
Costs depend on soil type, site access and project size. They are often more cost-effective than concrete once you factor in reduced labour, no curing delays and no concrete truck requirements.
Can concrete-free foundations be used for underpinning?
Yes. Ground screws, screw piles can be used for underpinning to stabilise and strengthen existing foundations with less disruption than traditional methods.
