Ground Screws
Ground screws are the fast, clean alternative to concrete foundations – and they've been our core offering for over 15 years. We're one of the UK's most experienced ground screw suppliers and installers, trusted by thousands of domestic and trade customers across the country.
About Ground Screw Foundations
Ground screws deliver a strong, stable, load-bearing foundation without the mess, waste, and waiting time of concrete. Whether it’s a backyard shed, a garden room, a run of fencing, a full timber deck, or a timber frame build, they adapt to projects of every size.
We supply ground screws for DIY self-installation and trade projects across the UK, with professional installation available nationwide for customers who want a fully managed solution.
How Ground Screws Work
Each ground screw is a galvanised steel shaft with helical blades welded to the lower section.
As the ground screw is rotated into the ground – either by hand using a ratchet tool or with a lightweight machine driver – the blades interlock into the soil and compact it around the shaft. This creates a dense, stable anchor point that resists both vertical pressure and lateral forces.
Once installed, the top of the screw sits above ground level, ready to accept a bracket that connects directly to your timber frame, joist, or post. The whole process is quick, clean, and reversible.

Why Choose Ground Screws Over Concrete?
Ground screws are hot-dip galvanised to BS EN 1461:2009 and backed by CE approval and a 20-year product guarantee. They’re built to last – and if your plans change down the line, they can be removed and even relocated. Try doing that with a concrete slab!
The benefits of ground screws are hard to argue with:
- Instantly load-bearing – no curing time, your build starts the same day
- Up to 37% cheaper than concrete for trade projects
- Zero waste, no skips, and no excavation
- No heavy machinery required for most domestic installs
- Environmentally friendly and TPO suitable
- Fully reversible – remove them cleanly and restore the site
