Ground screw foundations | RADIX

What is a ground screw?

A ground screw is a modern, eco-friendlier foundation solution that replaces the need for concrete foundations. They are galvanised steel screws of different diameters and lengths designed to act as a strong, secure, and durable foundation to support various structures that are attached to the screws from above. A ground screw can also be called a ground screw anchor, earth screw, ground anchor, foundation screw, and grounding screw.

We believe in our products and back the structural integrity of every screw with a 35-year guarantee based on typical soil conditions. Each screw or extendable screw pile has a different load capacity and dimensions, but all have a long lifespan of 60+ years.

Our screws and brackets are manufactured under EN ISO 9001:2015 quality management systems and finished following BS EN ISO 1461:2009.

Ground screw | Installation process | RADIX

Ground screw installations

From the moment we engage with you, right through to handing over to the team who will complete your building project, we will work tirelessly to meet your needs.

To select the best screws for your private or commercial project, we need to gather detailed information about your project, do a site survey and load-testing and then do our calculations to provide the empirical evidence of which screw is best suited.

On the day of the installation, we prepare the ground above and below, pre-drill if required, line up the screws and install them quickly using our range of ground screw machines. The entire process is extremely efficient and once the foundations are in they can instantly support the structure you are placing on top of them.
