Professional Installations Applications

Fast and easy installations

The simplicity of installing a screws means your project gets completed faster, with less effort and lower labour costs. Screw foundations save you money when you take all factors into consideration. Get a quote from us and we can show why they will suit your project more than concrete.

Cost-effective solution

Our calculations regularly prove when all factors are considered, screw foundations prove to be the most reliable, versatile and cost-effective solution for construction projects across all sectors. From DIY projects to large commercial installations, our screws are better value.

Long warranty and service life

RADIX foundation screws are expertly designed, engineered and manufactured to the highest standards, which we back up with a 35 year warranty, subject to soil and installation parameters. You can expect a long lifespan.

Eco-friendly foundation solutions

Screws have been designed to be as sustainable as possible, and contain less than 50% embedded carbon than an equivalent concrete base, the second biggest contributor to carbon emissions in the world. Add the facts they are easier and less damaging to install, moveable, reusable and recyclable, and you have a far better product for the environment.

Access difficult to reach locations

We only use the best quality installation equipment when installing our ground screw anchors. We can easily access hard to reach locations, and tight access areas. We rarely require the use of our heavy ground screw machines unless the project demands it. This would normally apply to large scale commercial projects.

Install ground screws all year round

No more costly delays with your project as our screw foundations can be installed in frosted ground and all year round, even in the cold winter months. Take advantage of our products and services and hit your deadlines and come in on budget! All our screws will withstand harsh climates without rusting due to the design.

No excavation or soil removal/fill

No ground excavation is needed when installing any of our range of screws. Subsequently, there are no refill or earth removal costs. Overall, the efficiency of our screws saves you time, energy, and costs.

Suitable for variable terrain and slopes

Our range of screws are suitable for most soil conditions and topography. Sloping and soft ground, rocky ground, boulders and clay are all manageable with screw foundations installed by us.

High and instant load-bearing capacity

There is no waiting about for concrete to cure, so once our screws are installed you can instantly support the structure. Our screws can carry high loads and are easily laid out to spread the above weight. We can go deep into the ground to obtain the maximum required torque to securely stabilise the structure.

Do ground screws have any disadvantages?

Ground Screws may not be suitable for some types of installations, and the cost of them could be more expensive compared to alternative solutions. The disadvantages can only be realised once a thorough analysis of what you want to build is looked at. The soil conditions may not be suitable and for a small project, our self-install ground screw starter kits may be better from a cost perspective, if you are willing to do the work yourself.

​Other ground screws and piling systems in the market have many disadvantages when compared to our brand, so ask us for advice, and don’t risk your construction with inferior screws.

Ground screws vs. Concrete foundations – Which is better?

In evaluating ground screws vs. concrete foundations, both options have their advantages and disadvantages. Ground screws offer faster installation, flexibility in challenging terrains, and a more environmentally friendly footprint. On the other hand, concrete foundations provide greater load-bearing capacity and strength, if you are building extremely large structures. Ultimately, the choice depends on the specific requirements of the project, considering factors such as time, budget, terrain, and sustainability goals.

Ease and Speed of Installation:
Ground screws offer a significant advantage in terms of installation time. Unlike concrete foundations, which require curing and drying time, ground screws can be quickly installed regardless of weather conditions. This can result in significant time savings for construction projects.

Flexibility in challenging terrain:
One of the major drawbacks of concrete foundations is their limited adaptability to challenging terrains. Screws, on the other hand, can be adjusted to accommodate sloped, rocky, or uneven surfaces, making them ideal for projects in such environments. This flexibility ensures stable and level foundations, even in difficult terrain.

Environmental friendliness:
Concerns about environmental impact have become increasingly important in construction. Screws offer a more sustainable option compared to concrete foundations. They emit significantly less carbon dioxide (CO2) during production, have less embodied carbon, and can be reused or recycled, reducing their overall environmental footprint.​

Load-bearing capacity:
While ground screws are a versatile option for most building projects, their load-bearing capacity might be limited compared to concrete foundations for large construction projects.

For large-scale multi-story structures or heavily loaded buildings, concrete foundations may be more suitable, offering greater stability and strength.​

For most foundation projects, screws will be a more cost-effective option when all factors are considered.

According to an article that appeared on Imperial’s news website, approximately 3.5 billion tonnes of Ordinary Portland Cement globally are produced every year. Every tonne produced releases up to 622 kg of carbon dioxide (CO2). This implies that the cement industry globally contributes a substantial 7% to the total anthropogenic CO2 emissions

More locally, a 2018 report by Chatham House disclosed that cement production accounts for roughly 8% of the world’s carbon emissions.

However, the industry and the UK government are taking steps to address this issue. The UK government has committed to transitioning to a low-carbon economy, and this includes most energy-intensive industries, such as cement production3.

In conclusion, cement production significantly contributes to carbon emissions in the UK and globally. However, sustained efforts are being made to address these concerns and transition towards more sustainable practices, like the use of screw foundations.

For some larger-scale construction projects, concrete foundations can be more cost-effective. The economies of scale associated with concrete production, availability of resources, and established construction practices often make concrete foundations a financially viable option. For many other larger-scale projects, our extendable helical screw pile foundations are the better option.
