Ground screws are engineered steel foundations that cater to a huge range of construction projects, from back garden DIY to heavy-duty commercial projects. Each ground screw is a strong galvanised steel shaft with helical blades that twist into the soil as it’s installed. Instead of digging trenches and pouring concrete, the screw is driven straight into the ground, creating an instant, secure foundation point.
Our ground screws come in a range of lengths and diameters to suit all sorts of projects. Shorter screws are well-suited for lighter jobs, such as sheds or decking, while longer, wider screws offer the capacity for garden rooms, annexes, extensions, and even commercial modular buildings.
Once installed, the head of the screw sits above ground, ready to connect with brackets that attach directly to your structure. This flexible design means they’re just as at home under a timber frame in a back garden as they are under solar arrays or larger commercial units.
In simple terms, ground screws give you the same outcome as a concrete foundation – a strong, stable, load-bearing base – but they do it faster, with less mess, and with the flexibility modern projects need.
The first thing most people notice about ground screws is the speed – but speed is only part of the story. Ground screws solve the frustrations that make foundations such a stressful stage of building. They simplify logistics, minimise disruption, and provide reliability from day one.
Fast Installation
Ground screws can often be installed in just a few hours using handheld or lightweight machinery. There’s no waiting around for materials to cure, so the structure can be built on the same day. For homeowners and contractors alike, this means faster progress and fewer delays.
Minimal Disruption
Because ground screws don’t require digging, skips, or concrete mixers, the installation process is quiet and tidy. They can be carried through narrow access points and fitted cleanly without damaging gardens or landscaped areas. It’s a straightforward process that avoids the noise, waste, and mess associated with traditional groundwork.
Built to Last
Manufactured from hot-dip galvanised steel, our ground screws are designed to resist rust and corrosion for decades. Once in place, they provide a dependable foundation for everything from small sheds to heavy commercial buildings. With minimal maintenance required, they continue performing year after year in most soil conditions.
Flexible Solutions
Ground screws are well-suited when concrete bases are difficult or impractical to lay, such as on sloping ground, in tree protection zones, or in tight urban sites. They can be installed at varying depths and heights to create a perfectly level base, even on challenging terrain. If the structure ever needs to move, the screws can be removed and reused without leaving a trace.
Lower Environmental Impact
Installing ground screws avoids excavation, leaving soil structure and drainage patterns undisturbed. No concrete is poured, no skips are filled, and no waste is sent to landfill. At the end of their use, the screws can be completely removed, allowing the land to return to its original condition.
Better Value
Quicker installation means lower labour costs and fewer site visits. With no excavation, there are no disposal fees or skip hire charges, and less money is tied up in site preparation. The ultimate result is a foundation system that consistently saves both time and money.
Ground screws create strong, reliable foundations by anchoring deep into stable soil layers. Instead of spreading loads across a wide slab, each screw transfers the weight of your structure straight down its shaft and into the earth. The helical blades lock into the ground, preventing both downward movement and uplift from wind or shifting soil.
The Main Components
Steel shaft: the body of the screw, available in a range of lengths. Shorter screws are suited to decking or sheds, while longer models support garden rooms, annexes, and even multi-room modular buildings. Helical plates: the spiral blades welded around the shaft. These cut through the soil during installation and provide the mechanical anchoring that holds the screw in place. Mounting head: the connection point at the top of the screw. Different head designs work with brackets, timber joists, steel frames, or modular bases. Galvanised coating: each screw is hot-dip galvanised, immersing the steel in molten zinc to create a protective layer that resists corrosion for decades.
The Installation Process
Installation is typically straightforward. The footprint of your structure is marked out, and screws are placed precisely where support is needed. Using either manual tools for small projects or machine-powered drivers for larger builds, the screws are rotated into the ground until they reach the right depth and resistance. Most installations take just a few hours. There’s no drying time, no need for multiple site visits, and no pause before construction can begin – your structure can be built immediately.
Working With Different Sites
Because screws are installed individually, they can adapt to conditions on site. On a sloping garden, each screw can be set at a slightly different depth and still provide a perfectly level frame. When tree roots or underground services are present, screws can be positioned carefully around them without disturbing what’s below the surface.
Long-Term Durability
Ground screws are built for decades of service life. The hot-dip galvanised coating resists corrosion even in challenging soil conditions, while deep anchoring means they’re unaffected by surface soil movement or frost action that can damage shallow foundations.
For decades, concrete was the default choice for foundations. Strong, solid, and familiar – but also slow, messy, and resource-heavy.
Ground screws achieve the same goal of stable, load-bearing support, but in a very different way. Understanding the difference helps you see why so many builders, homeowners, and developers are making the switch.
Both systems achieve stable foundations, but ground screws do so faster, cleaner, and more sustainably. Whether you’re building a garden office, a school classroom, or an entire solar farm, screws offer the strength of concrete without the disruption.
That’s why more builders and homeowners are choosing them – and why concrete is no longer the default answer for foundations.
Installation speed
Concrete: Requires excavation, formwork, mixing, pouring, and curing. The process typically takes days, sometimes weeks, before you can even start building. Ground screws: Installed in hours with compact equipment. As soon as the screws are in, the base is ready – no drying, no waiting.
Site impact
Concrete: Excavation means spoil heaps, skips, heavy machinery, and disruption to gardens or landscaping. Once poured, the ground is permanently altered. Ground screws: No digging, no waste, and no large machines. The screws slot neatly into place, even in tight access gardens or sensitive sites, leaving lawns and borders intact.
Flexibility
Concrete: Permanent once in place. If your plans change or you need to move the structure, the only option is to break it up and dispose of it. Ground screws: Fully reversible and reusable. Screws can be removed cleanly, relocated, or adjusted without major upheaval.
Environmental impact
Concrete: Cement production accounts for around 8% of global CO₂ emissions. Disposal also creates long-term waste. Ground screws: Produce around 60% less CO₂ during manufacture and installation. They preserve natural drainage patterns and can be removed at end of life, leaving no permanent trace.
Cost considerations
Concrete: The headline material cost may look low, but once you add machinery, waste removal, labour, and delays, the true price is much higher. Ground screws: The product price is comparable, but installation is faster, cleaner, and requires fewer people on site – meaning significant savings in real-world budgets.
Installation is typically straightforward. The footprint of your structure is marked out, and screws are placed precisely where support is needed.
Using either manual tools for small projects or machine-powered drivers for larger builds, the screws are rotated into the ground until they reach the right depth and resistance.
Because the blades cut and compact the soil as they go, the surrounding earth strengthens during installation. Once the screws are in place, brackets are fitted to the heads, providing level mounting points ready to connect directly to timber, steel, or modular frames.
Most installations take just a few hours. There’s no drying time, no need for multiple site visits, and no pause before construction can begin – your structure can be built immediately.
Because screws are installed individually, they can adapt to conditions on site.
On a sloping garden, each screw can be set at a slightly different depth and still provide a perfectly level frame.
When tree roots or underground services are present, screws can be positioned carefully around them without disturbing what’s below the surface.
For homeowners, this means confidence that their garden room or deck will stay level year after year. For businesses, it means foundations that won’t compromise their long-term investment.
Every site is different, and ground conditions vary widely even within the same property. This used to mean complicated groundwork, soil disposal, or expensive site preparation. Ground screws, however, can adapt to almost any soil type.
Clay is one of the most challenging soils for traditional foundations. In wet weather, clay swells and becomes soft; in dry spells, it contracts and cracks.
This constant cycle can undermine shallow foundations. Ground screws bypass the unstable top layers by driving deeper into consistent material below. Once anchored, they remain unaffected by the surface-level shrinking and swelling.
Loose, sandy soils often struggle to hold posts or shallow foundations because the grains shift under pressure.
Ground screws perform well here – the helical plates compact the surrounding sand as they rotate in, increasing density and creating a strong mechanical lock. This makes sandy sites far more straightforward to build on than many expect.
Peat and soft organic soils lack the density to support structures on their own.
Instead of requiring full excavation and replacement with hardcore or concrete, ground screws can be installed at greater depths to reach firmer strata. Longer screws ensure reliable anchoring, providing strength without the cost or disruption of soil replacement.
Rocky ground presents obvious difficulties for digging. But for screws, rocks are less of an obstacle.
Installation tools can work screws between stones and boulders, anchoring directly into the stable material without large-scale excavation. In many cases, only minor site preparation is needed.
Sloping ground usually means levelling the site through excavation or building retaining walls – both of which are disruptive and costly.
Ground screws avoid this by being installed at different depths, then levelled at the head. The result is a flat, stable foundation without reshaping the landscape.
Because ground screws transfer loads into deeper soil layers, they remain stable even as the topsoil changes due to weather and temperature fluctuations.
Rain, frost, or drought may affect the surface, but the foundations below stay firm. For builders, that means fewer worries about movement or subsidence.
How long do ground screws last?
Our screws are hot-dip galvanised and CE approved, with a 20-year guarantee as standard. In most cases they’ll last decades longer, giving you reliable foundations for 30–50 years depending on conditions.
Will ground screws work in my soil?
Most likely, but do ask us first. We’ve supplied screws for clay, sand, peat, and even rocky ground. With different lengths and specifications, we can match the right product to your site. If in doubt, our team can advise.
Do I need planning permission for ground screws?
Ground screws themselves don’t require permission, but the structure you’re building might. If you’d normally need permission for an extension or large garden building, you’ll still need it regardless of the foundation type.
How strong are ground screws?
Properly installed, screws handle everything from small sheds and decks to full modular buildings. For larger projects, we carry out on-site load testing and provide the documentation needed for building control.
Can I install ground screws myself?
Many people do. With the right tool (which can be rented or purchased), you can install screws for sheds, decking, or even garden rooms. For bigger builds or when paperwork is needed, our installation teams cover the whole of the UK.
What if I change my mind later?
Unlike concrete, screws can be removed cleanly – and even reused. That makes them ideal for temporary structures or projects that may evolve.
