Foundation screws

Faster, safer and more effective!

Foundation screws are particularly versatile.

In particular, they adapt to all kinds of flooring: the screws are designed to resist corrosion, thanks to hot-dipped galvanised steel, in accordance with the DIN EN ISO 1461 standard (Magnelis® coating). An epoxy coating is also possible when dealing with particularly corrosive soils. As a result, screw-in structures are perfectly suited to topsoil, clay, chalk, rock (drilling is required), concrete and more. They are highly resistant, stable and durable, and can withstand extreme vertical and horizontal pressures.


The other benefit of this solution is that it does not require any levelling, excavation or concrete works. This means the system can be installed quickly and in an environmentally friendly fashion because the screws do not damage the soil (no waterproofing) and are fully reversible. Charging is also immediate, and no earth connection is necessary.

*Lifespan-Corrosion Resistance: coordinated verification processes for the entire lifespan, based on professional corrosion Hot-dipped galvanised steel in accordance with the DIN EN ISO 1461 standard (an option for very corrosive soils: double epoxy coating)

Advantages

Save time and money

  • Reduction in installation time
  • Immediate installation of the screw-in foundation

No impact on the earth

  • No levelling or excavation
  • No concrete, no impact on the environment and no waterproofing of the soil
  • Environmentally friendly

Easy to use on all kinds of soils and in all kinds of weather

  • Topsoil, clay, chalk, rock, concrete, etc.
  • Rain, frost, snow.

Test and verified

  • Screws tested statically and verified by a number of authorities: Socotec, Geotec

Highly resistant

  • Hot-dipped galvanised steel in accordance with the DIN EN ISO 1461* standard
  • Stable and durable over time
  • Extreme resistance to vertical and horizontal pressure

Driven support columns

Affordable, quick and easy to install!

This solution is well suited to stable soils. Driven support columns are particularly affordable and quick to install, due to the lack of accessories and the ease of assembly. They are also more resistant to shearing than foundation screws, which allows for a larger distance between columns. It is even possible to use a single support column for smaller structures, which would normally require a minimum of two screws.
Like foundation screws, driven support columns do not have an impact on the soil, and are completely reversible and easy to take apart. Simply pull them out.

However, for hard or corrosive soils, it is better to use foundation screws, which are shorter and require a smaller treatment surface. Screws can also be adjusted, unlike driven support columns.

Advantages

  • Affordable (no accessories, less materials)
  • Fast installation
  • High resistance to shearing, allowing a greater distance between columns
  • Can be used as a single support column
  • No impact on the soil
  • Reversible

Ball joint base on a stringer

The solution to different elevations

This unique foundation solution is used when digging is impossible (backfill, technical landfills, presence of contractors). SigueSOL® ball joint bases are placed on stringers and allow for a 10% incline. As a result, this solution can compensate for any uneven levels in the ground, as well as different elevations.
Thanks to the telescopic device used to adjust the height of the feet on these structures, this kind of solution can adapt to changes in the terrain over time.

Advantages

  • Perfect for CETs
  • Compensates for uneven ground (can incline up to 10%)
  • Compensates for different settling behaviour
  • Two possible adjustments (inclination, height)

Anchor plates

Anchor plates are used for hard soils (concrete, tarmac) that cannot be excavated. They can be used in conjunction with other kinds of foundations, such as screws. They are more widely used to construct inverter shelters (technical rooms).

  • No excavation required
  • Compatible with hard soils (concrete, tarmac)
  • Can be paired with other foundation solutions
