This is the most common question we get asked, and the answer is ‘yes’! Ground screw foundations are an excellent alternative to traditional concrete foundations, particularly for sustainable construction. Despite the familiarity and long-standing use of concrete, ground screws offer several significant advantages. They can be installed much faster than concrete, which requires time for pouring and curing. Ground screws are less invasive and have a lower environmental impact, as they don’t require extensive digging or soil displacement. Additionally, they can be easily removed and reused, providing flexibility for temporary or relocatable structures. High-quality ground screws also offer strong load-bearing capacities comparable to concrete, and they can be more cost-effective due to reduced labor and time requirements.

RADIX ground screws are designed to last over 60 years, contingent on soil conditions and installation quality. Additionally, each screw comes with a 35-year guarantee ensuring structural integrity.

Yes, our foundations can be installed year-round, proper planning and professional assessment ensure successful installations, unlike concrete foundations, which are limited by weather conditions.

RADIX PRO screws offer load-bearing capacities ranging from 13.5kN to 66kN. Each screw undergoes rigorous testing to ensure it meets load, pressure, and tension-bearing standards. Our installation teams assess the ground conditions and perform calculations based on the specific structure that the screws will support. The total load capacity of the structure is distributed across multiple screws.

One key advantage of ground screws over concrete is that they can be installed during winter months, even in frosted ground. Our screws are specifically designed to perform well in various terrains, climates, and soil conditions.

Yes, ground screws can be installed through tarmac. First, a hole must be drilled to ensure clean insertion, using appropriate equipment to avoid excessive wear. Careful installation ensures proper alignment and depth, while assessing the underlying soil guarantees sufficient support. Due to the complexities, professional installation is recommended for safety and accuracy.

The depth at which a ground screw needs to be installed depends on the overall weight of your project and the ground conditions. Our screws, available in lengths from 800mm to 2050mm, are designed to create strong and stable foundations in most soil types for a wide range of projects. For deeper installations, we offer a screw pile range to meet your project’s specific requirements. Please contact us to evaluate your project and help you select the best screws for your build.

Yes, ground screws can be installed on a variety of terrains. RADIX’s low-carbon foundations are highly versatile and suitable for numerous surfaces. To ensure the right screws are chosen for your project, accurate site surveys, ground testing, and load testing are essential. Our screws work well in various soft soils, including clay, silt, and loam, where they easily penetrate and provide stable anchorage. They are also ideal for grassy fields, gardens, and other unpaved surfaces. In rocky terrains or extremely hard soils, pre-drilling may be necessary. Waterlogged or marshy areas may require special considerations for stability and longevity, which our range of screws can accommodate. For installations in concrete or asphalt surfaces, pre-drilling is often required to ensure secure anchorage in highly urbanised or paved environments.
