How much do ground screw foundations cost

A real project cost example *

If we take a 6m x 3m garden room being installed on level ground, adhering to building guidelines, there are savings with ground screws.

The cost of installing a 0.15m deep concrete base, including excavation with spoils remaining on-site, materials and labour, is £2,520.

Ground Screws
Without digging, causing mess or damage to the garden, the supply and installation of our ground screws with a timber frame is £2,205.

The cost of concrete foundations increases significantly on sites with areas of sloping or unlevel ground, which will require more excavation, removal of spoils, materials and labour. We only need to select longer screws!

The real value in ground screw foundations

As well as being the more sustainable choice over concrete, you can take advantage of the many benefits of ground screw foundations:

  • Install in hard-to-access areas
  • Install over sloping and uneven ground
  • Install all year round and in any weather
  • No digging. No damage. No concrete.

To make your project run as smoothly as possible, we can also design, supply and install a timber or steel frame specifically for your project so that you can get building on your new base right away.
