Whatever you're building on, screws solve the same problem
Getting a solid, level foundation into a real garden — without the excavation, mess, and delay that come with concrete. Here's how that plays out for two very different jobs.
Get it right the first time
A ground screw base gives you a perfectly level platform to build on — even if your garden slopes or the ground's uneven — because each screw is adjusted independently until the whole base is true.
There's no waiting for concrete to cure and no ruined lawn, so your building often goes up the same day the base goes in. And because it sits raised and clear of the ground, you avoid the damp and movement that shorten a building's life later on.
Fix it without tearing up the garden
Sticking doors, an uneven floor, or creeping damp usually mean the base underneath has moved or failed. Ground screws fix that using compact equipment that reaches spaces a digger never could — around patios, borders, and tight side passages.
You get a new, properly level base — and because the building sits raised and clear of the ground, you remove the moisture and movement that caused the problem in the first place.

How a Ground Screw Base Works
Getting a solid, level foundation into a real garden — without the excavation, mess, and delay that come with concrete. Here's how that plays out for two very different jobs.
Ground screws are helical steel posts, mechanically driven into the ground with specialist equipment. The helical thread compresses the soil as it goes, creating exceptional load-bearing strength — no digging, no pouring, no spoil to cart away.
When a ground screw isn't the right solution
We install all four base types, so we've no reason to talk you into the wrong one. A ground screw base is the right call for most garden buildings — but not every one. We'd point you towards a different option if:
You're on solid, level ground and want the lowest-cost option.
An eco-plastic grid or adjustable feet may do the job for less. → Eco-Plastic Base
You're placing a lightweight structure on an existing patio or slab
Adjustable feet are often quicker and cheaper there. → Adjustable Feet
You specifically want a solid slab underfoot
For a very heavy build, a garage, or a heavily loaded floor. A concrete base may suit better. → Concrete Base

Most bases are installed in a single day, and we can often put the building up the same day too.
No — that's the point. They're driven straight into the ground, so there's no digging, no pouring, and no curing time.
Yes. Each screw is adjusted independently, so we can create a perfectly level platform even where the ground slopes or is uneven — one of the situations where screws clearly beat concrete.
Typically 1.2–1.8 metres for UK soil, below the frost line. Exact depth depends on your ground conditions, building size and usage which we assess before finalising your order and installing.
For garden buildings, yes — and more stable in many cases, because the base moves slightly with the ground instead of cracking. For extremely heavy loads we may recommend concrete, and we'll tell you if so.
Yes — unlike concrete, screws can be extracted, so the base is removable and reusable.
We provide a lifetime guarantee on all our ground screws when they installed by our qualified installation teams.
The price of a ground screw base depends on several factors such as size, length of screw required. Complete our quick quote form and we'll send you an estimated price in 60 seconds.

Two garden buildings, two locations, one ground screw system
Getting a solid, level foundation into a real garden — without the excavation, mess, and delay that come with concrete. Here's how that plays out for two very different jobs.
Sloping ground the perfect scenario for ground screws
The garden sloped noticeably from one side to the other, which had ruled out a simple slab and left the customer worried their new summer house would end up sitting unevenly. Rather than dig out and level the whole area, our team set ground screws at varying depths and adjusted each one until the frame was perfectly true — turning an awkward, uneven plot into a solid, level platform in a single day.
A new base and garden shed to replace aging building
The old shed and base had seen better days - the floor had gone soft in places, the door no longer shut properly, and damp had started creeping into the timber. We cleared away the tired structure and its crumbling base, then installed a fresh set of ground screws to give the replacement building a proper, level foundation to sit on.
