What size are ground screws?

Ground screws are a strong and sustainable alternative to concrete. They offer a robust and level foundation solution for projects over sloping and uneven ground and in hard-to-access areas.

Available in various diameters and lengths, RADIX Ground Screws provide support for a variety of commercial and residential applications:

  • Garden rooms and home offices

  • Home extensions and granny annexes

  • Ground-mounted solar arrays

  • Holiday cabins and glamping pods

  • Sports buildings and structures

  • Bus shelters and roadside signage

  • And more

RADIX Extendable Screw Piles

When facing challenging projects where the ground is significantly sloping or made up of areas of soft ground, we turn to the RADIX EXT 76mm.

RADIX Extendable Screw Piles are made up of a screw tip, with extension pieces in 500mm, 1000mm, 1500mm and 2000mm lengths, allowing us to bring up levels quickly and install through the areas of soft ground to reach more solid stratum to achieve the load-bearing capacities required for projects.

The RADIX EXT range is also available in 89mm and 114mm diameters to achieve greater load-bearing capacities.
