The use of screw piles in the construction industry, whether for residential houses or industrial buildings, is very extensive.

You can learn more by browsing articles dedicated to various construction sites, however, the use of screw piles in the building industry can be classified into 4 categories.

New construction


Screw piles are often appreciated by builders of modular buildings made of wood and metal, due to the ease of placing the superstructure of the building once the piles are in place.

Screw piles have many advantages, including:

  • Generally lower cost compared to foundations requiring concrete pouring
  • The ability to chain operations: the builder does not have to wait for weeks to intervene: once the last pile is installed, the foundation is ready to receive the building.

However, screw piles also have disadvantages and specific usage requirements: there are soils where these piles cannot be used. These are soils containing rocky debris or soils that may present premature refusal due to the possible presence of blocks.

In case of soils containing stones, the piles may be eccentric to their initial position during installation. This is compensated for by the installation of special plates and does not in itself present a non-conformity.

Any type of building or house can be constructed on screw piles – in wood, concrete, metal, modular and prefabricated, or traditional.

Extensions and terraces

Screw piles are suitable for building decks and carrying out extensions on existing buildings. Depending on the technique used to construct the existing building, the piles can be positioned more or less close to the existing building.

Underpinning works involve repairing existing defective foundations by taking them over. Often, the disorders caused by existing foundation defects manifest themselves in the form of cracks or deformations of floors or roofs. In general, these disorders can be repaired by reinforcing the existing foundation with screw piles. The piles are placed as close as possible to the building, and with the help of special jacks, the building is lifted at the lowered areas, if feasible. If it is not feasible, it is just stabilized in its position in order to prevent the worsening of the damage and immobilize the deformations.

Also, in case of raising the building, its foundations are strengthened by the same method.
