Steel pipe piles

Displacement pile in accordance with DIN EN 12 699

Steel pipe piles are both displacement piles and driven precast piles in accordance with DIN EN 12 699. They can be used as deep foundation elements for every type of structure. Using steel pipe piles improves the subsoil by fully displacing the soil instead of extracting it. This saves on additional costs for transport and landfill disposal.

One of the most persuasive features of the steel pipe pile is its short production time and comparatively low equipment and space requirements.


Steel pipe piles are particularly suitable for rebuilding the foundations of existing buildings in confined spaces, as they do not require a great deal of clearance from existing buildings.

Examples include:

  • Restricted heights and confined spaces (building in existing structures)
  • small quantities of piles
  • in contaminated subsoils (because the soil is fully displaced and not extracted)
  • Industrial buildings
  • Electricity and mobile phone masts
  • Conduits

Please contact us for advice on how to use steel pipe piles for your individual project.


The pile system is particularly suitable for small quantities of piles and confined spaces.  

  • Economical – even for small quantities of piles: quick assembly and dismantling, so shorter construction times
  • Flexible use, even in confined spaces
  • Comparatively low equipment and space requirements
  • Full soil displacement, no excavated soil to transport
  • High buckling resistance, able to absorb H-loads and bending forces
  • Pipes can be extended to achieve very long pile lengths
  • Comparatively low-noise production due to internal pipe driving
  • Can also be produced in particularly poor soft layers
  • Steel pipes are also resistant to concrete aggressive groundwater and chemical attack
  • Compression and tension piles as well as plumb and raking piles are feasible


Reusable and environmentally friendly

Steel is a material that can be reused as many times as desired. It is 100% recyclable. Using this system improves the subsoil by fully displacing the soil instead of extracting it. This saves on transport and thus cuts down on CO2 emissions. Steel pipe piles have proven especially effective in construction projects on contaminated sites.

Basic facts

Standards and regulations

Steel pipe piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12699 and the recommendations of the “Piles” working group (EA-Pfähle). The usual pipe diameters are 219mm, 356mm and 406mm. Loads and pipe diameters should be adapted to the prevailing soil conditions. We will be happy to advise you on this.


A starting pipe, which is closed at the base, is driven into the ground using inner pipe ramming. Extension pipes can be attached and welded in place around the circumference, if required, so that the workflow can continue. Once the final depth has been reached, the pipes are filled with concrete and the heads are reinforced to secure the connection.

The steel pipes remain in the ground in their entirety and act as additional protection against concrete aggressive water and soft strata. Excess piping is trimmed off after the required depth has been reached. The steel profile is capable of bearing the loads on its own.

Flexible use

Steel pipes are relatively lightweight, which means that the piles can be produced with a small, compact device. This allows the pile foundations to be produced in very confined and challenging spaces. The inner pipe ramming method allows the piles to be driven gently into the ground with virtually no vibrations, even in the immediate vicinity of existing buildings.

Quality assurance

The requirements of the relevant European and national standards must be complied with to ensure quality assurance during construction. Our steel pipe piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12 699 and the recommendations of the “Piles” working group. Self-monitoring and documentation of construction are regulated by the manufacturing standards.

A procedure instruction that is individually adapted to the requirements of the relevant project is required to install steel pipe piles.

We ensure high execution quality with:

  • Individually coordinated instructions
  • Compliance with the requirements of DIN EN 12 699, Eurocode 7 and EA-Pfähle
  • Clear processes governed by our quality management system in accordance with DIN EN 9001:2015
  • Static or dynamic pile load testing
  • Vibration readings
  • Constant monitoring of the injection agent
  • Digital monitoring and evaluation of the manufacturing parameters

Design variants

Steel pipe piles can be supplied in the following design variants:

  • Plumb or raking pile
  • Compression and/or tensile pile
  • Pile reinforced at the head or along the entire length of the pile
