Ground screws create strong foundation points without digging trenches or pouring a traditional concrete base. Forti Nova supplies and installs ground screw foundations across the UK.
The next construction stage does not depend on waiting for a concrete pour to cure.
Ground screw projects can reduce excavation and spoil handling compared with poured foundations.
The screw positions should match where the building needs support.
Ground conditions and access affect the screw size, depth and installation method.
A ground screw foundation uses steel screws installed into the ground at the points where the building needs support. That removes the need to dig a trench or pad and pour concrete for the foundation itself.
The screw is only one part of the job. The positions, depth, brackets or beams and the ground all need to work together so the building above is properly supported.
So the first question is not “which screw is cheapest?” It is “what does this building need underneath it?”
Forti Nova is not limited to one product or one installation method. The route depends on whether the foundation is already specified, still needs developing or requires specialist commercial equipment.
Ground screws, heads and components supplied against a suitable project specification for trade, repeat and self-managed installations.

Ground screws can reduce excavation and remove the need to wait for concrete curing. They are especially useful where the structure can be supported efficiently on discrete foundation points.
Concrete remains appropriate where the structure, ground, slab requirements or design strategy favour a continuous or conventional foundation solution.

Commercial case study · ScotlandA difficult-ground foundation completed with specialist equipment.The strongest evidence is a completed project with visible equipment, site conditions and an independent customer review. Our featured Scottish commercial project shows Forti Nova succeeding in difficult woodland ground after earlier approaches had not delivered.
The wider project library publishes locations, screw quantities, services and dates only where those details exist in the underlying record.

Direct answers on foundation choice, specification, price, depth, load capacity and UK supply or installation.
Ground screw foundations use steel screws installed into the ground to support a building without digging trenches or pouring a traditional concrete base. The screw size, depth and position depend on the building and the ground at the site.
There is no single ground screw that is best for every foundation. The right one depends on the building weight, ground conditions, screw size, corrosion protection, fixings and installation method. Length or price alone is not enough to choose a structural ground screw.
Compare specification factorsCost depends on the screw size, how many are needed, the building, ground conditions, site access, travel and whether brackets, beams or installation are included. Compare the full foundation cost rather than the price of one screw.
Ground screw cost and pricesThere is no single weight figure that applies to every ground screw. Capacity depends on the screw, how deep it is installed, the ground, the direction of the load and how the building connects to it. Structural projects need calculations based on the actual job rather than a generic online number.
Understand load calculationsGround screw depth varies from job to job. It depends on the screw type, the weight it needs to carry and what the ground is like. A fixed depth should not be copied from another project.
Read the size and depth guideThe terms are often used in the same way, but not every screw pile or helical pile is the same product. On this site, a ground screw foundation means a foundation using structural ground screws chosen for the building and the site.
Ground screws can be a better fit where reduced excavation, limited site disruption and avoiding a concrete curing period are valuable. Concrete remains appropriate for other structures and site conditions, so the right choice should be made at project level.
Compare ground screws and concreteForti Nova supplies ground screw systems and supports ground screw foundation installation for projects across the UK, including garden rooms, decking, sheds and cabins, extensions, modular buildings and framed structures.
View installation supportThey can support substantial structures where the selected system, layout, ground evidence, connections and structural calculations are suitable. These projects require an engineered foundation approach rather than a standard garden-building layout.
Read the compliance guideYes. Forti Nova supplies ground screws, heads and related components for suitable self-managed, trade and repeat projects. Provide the existing specification or enough project information to establish what still needs to be confirmed.
View supply-only ground screwsYes. Forti Nova can mobilise specialist installation equipment for suitable commercial projects. The featured Scotland case study documents 36 commercial-range ground screws installed in difficult woodland terrain after earlier approaches had not delivered.
