Ground screw and screw pile foundations for decks, terraces and pergolas
Stable base, mechanical installation. No concrete, no excavation, no mess in the yard.
Suitable for
Concrete scenarios where this solution works well.
Timber or composite terrace
Relaxation platform in a private yard, point foundations, fast installation, no screed and no concrete pouring.
Freestanding pergola
Shade structure anchored on screw foundations. It requires no additional approvals beyond those for the pergola itself.
Barbecue or lounge platform
A defined, levelled area in the yard, built quickly and repositionable later if you change your plans.
Yard reorganisation or extension
Redefine the outdoor space without major excavation. The foundations need no curing time, so the terrace is usable immediately.

How it works
The main steps from order to handover, for this category.
Ground and site assessment
We check the ground type, level and access. We determine the number and depth of the foundations.
Laser setting-out
We mark the exact foundation positions for a perfectly aligned result.
Foundation installation
We screw them in mechanically with our specialised installer. No concrete, no vibration, no mess.
Levelling and handover
We align the support platform, check it is level and hand it over. Your terrace is ready to build on.
Advantages
What makes this solution better than the classic alternatives.
No concrete
You don't wait for it to dry, you don't make a mess, you don't block the yard for weeks.
Reversible
The foundations can be unscrewed if you change your plans. The ground stays intact.
Same-day installation
A small terrace is finished in 4–8 hours. You can continue with the deck or the pergola the next day.
Stable on uneven ground
The foundations compensate for level differences. They also work on gentle slopes.

M76 for platforms and lightweight structures; V76 for configurable depths
What you need to send us
The location, dimensions, the sketch or plan, known weight or loads, photographs of the ground and the desired deadline.
What we check
The ground, access, bearing points, the connection to the structure, vertical and lateral loads and the possibility of installation.

Frequently asked questions
What customers usually ask about this category.
It depends on the area and the number of foundations. A 20–30 sq m terrace: 4–8 hours. Larger areas or those needing extra ground preparation: 1–2 days.
Yes. On clay we adapt the depth and diameter of the foundations. We assess the soil type on site and choose the right solution.
Yes. They are unscrewed mechanically without damaging the ground. Useful if you want to reposition the terrace or remove it completely.
From small platforms of 6–8 sq m to terraces of 50+ sq m. There is no standard limit; we adapt to the project.
It depends on the area, the locality and the nature of the construction. For planning clarifications, the town hall or an architect can guide you quickly.
