Ground screw applications

What can ground
screws support?

From garden rooms and decking to extensions and steel frames. Tell us what you are building and we can work out the right foundation for the building and the site.

Capability for more demanding structures and sites.

Commercial work needs more than a product list. Loads, ground, access, plant, connection details and installation records have to work together. Forti Nova supports developers, contractors, modular building companies and structural project teams across the UK.

The Scotland project shows that capability in practice: difficult terrain, earlier approaches that had not delivered, specialist excavator-mounted tooling and a completed foundation backed by a verified customer review.

Why the foundation can change

Two garden rooms can still need different foundations.

01

Building

A larger or heavier garden room may need more support points or a different screw size.

02

Ground

Soft, sloping or obstructed ground can change the screw size, depth and layout.

03

Fixings

Timber and steel frames can need different brackets, heads or support beams.

Application FAQs

What people ask before choosing ground screws.

Direct answers on garden rooms, decking, extensions, houses, solar mounting and what ground screws are used for.

01

What are ground screws used for?

Ground screws can support garden rooms, decking, sheds, log cabins, extensions, modular buildings, steel frames and some solar structures. The right screw size and layout depend on what you are building and what the ground is like.

02

Can ground screws be used for garden rooms?

Yes. Garden rooms are a common ground screw application because the floor or frame can often be supported efficiently on discrete foundation points.

03

Can ground screws be used for decking?

Yes. They can support timber, composite and raised decking. The screw positions should follow the deck beams and joists, with the screw size chosen for the ground and load.

04

Can ground screws be used for an extension?

Yes, on the right project. An extension needs a proper foundation design that takes account of the building weight, ground conditions, how it joins the existing house and any Building Control requirements.

05

Can you build a house on ground screws?

Ground screw and helical pile systems can support substantial structures when they are properly designed, specified and verified. A house foundation is an engineering project and should not be selected from generic domestic ground screw guidance.

06

Can ground screws be used for solar mounting?

Yes. Ground screws are used for some ground-mounted solar structures. The screw and layout need to be designed for the weight of the system and the wind forces acting on it.
