The FTH 76×1500×4.0 mm ground screw is designed for weak and soft soils – fill, clay and wet ground where a standard screw cannot develop enough bearing capacity. Besides the continuous spiral, it has an additional Ø200 × 8 mm helix at the lower end that enlarges the bearing area and grip. The 4 mm wall and Ø200 × 8 mm flange make it suitable for houses and heavy structures.
Key benefits
- Additional Ø200 × 8 mm helix for higher bearing capacity in weak soils
- Reinforced 4 mm wall
- Ø200 × 8 mm flange with central 1 × M16 bolt
- Hot-dip galvanised to EN ISO 1461 – long-lasting corrosion protection
- No digging, no concrete – can be loaded right after installation
- Does not disturb soil or roots; removable and reusable

Applications
- One- and two-storey prefab houses
- Bungalows and modular buildings
- Garages, canopies and halls
- Platforms, walkways and terraces
- Steel and timber structures
Installation
Installed by machine – with a hydraulic or electric ground screw driver. Spacing is defined by the structural design; for most structures it is between 1.5 and 3.0 m.
Why a ground screw instead of concrete?
A ground screw is a ready foundation in minutes: no excavation, no formwork, no concrete and no curing time. It leaves no construction waste, works even with a high water table, and can be unscrewed and relocated if needed – saving time, labour and often a significant part of the foundation cost.
