Cast-in-place concrete driven piles
Deep foundations with full soil displacement

Cast-in-place concrete driven piles are used as deep foundation elements when loads need to be transferred to deeper, load-bearing subsoil layers. Thanks to a range of design options, they can be adapted to suit different subsoil conditions and project requirements. The selection and design are based on the geological, technical and project-specific conditions.

Displacement piles
in accordance with DIN EN 12 699

Cast-in-place concrete driven piles are full-displacement piles used in special civil engineering. They are employed as deep foundation elements for various building and infrastructure projects and transfer loads into load-bearing soil layers. They are constructed without conventional soil excavation; instead, the soil is displaced laterally. Installation is carried out dynamically and, depending on the pile type, involves either internal pipe driving or head driving.

We offer the following variants:

Application

We use cast-in-place concrete driven piles as deep foundation elements for all types of structures. These include, amongst others:

  • Industrial buildings
  • Bridges
  • Wind turbines
  • Logistics centres
  • Residential and commercial buildings
  • Office buildings and hotels

Benefits / Features

Cast-in-place concrete driven piles are used as full-displacement piles for a variety of foundation applications. As the soil is completely displaced, no conventional drill cuttings are produced during construction. Pile lengths can be determined on a project-by-project basis, taking into account the ground conditions as well as the resistance values determined during construction.

The benefits / characteristics of driven piles:

  • Load transfer: Suitable for a range of load and foundation requirements
  • Pile geometry: Adaptation to site-specific ground conditions
  • Material usage: Slender pile geometries with concrete requirements tailored to the project
  • Ground management: Full-displacement method without conventional drill cuttings
  • Scope of application: Suitable for use even on contaminated sites
  • Construction: Installation method with project-specific installation speed
  • Resistance-settlement behaviour: Design in accordance with project-specific requirements
  • Pile inclination: Vertical and inclined piles possible up to an inclination of 4:1
  • Energy piles: Versions suitable for geothermal use are possible
  • Greenpile®: Cast-in-place concrete driven piles can be used as part of the Greenpile® system

Basic facts

  • Frankipfahl NG® piles
  • Simplex piles

Our driven piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12 699 and the recommendations of the “Piles” working group (EA-Pfähle). Diameters range from 420 mm to 710mm. Pile lengths of up to 40m are possible. 

The following types of foundations are possible:

  • Single pile foundations with one-dimensional load transfer

  • Group pile foundations with two-dimensional load transfer

  • Special case: combined pile raft foundations
     

The wide variety of available variants allows us to adapt to the most diverse subsoil conditions and construction site scenarios in order to achieve high load-bearing capacities.

Quality assurance

When constructing cast-in-place concrete driven piles, the requirements of European and national standards, as well as the recommendations of the ‘Piles’ Working Group (EA-Pfähle), must be taken into account. Self-monitoring and documentation of the construction work are governed by the relevant construction standards.

Construction is carried out on the basis of project-specific procedures. The selection and adjustment of construction parameters depend on the respective subsoil conditions, load requirements and project specifications. The specialist equipment is operated by suitably qualified personnel.

Principles of execution

  • Project-specific procedural instructions
  • Requirements in accordance with DIN EN 12699, Eurocode 7 and EA-Pfähle
  • Quality management system in accordance with DIN EN ISO 9001:2015
  • Static and dynamic pile load tests
  • Pile integrity tests
  • Documentation and self-monitoring in accordance with construction standards

Design variants

We always work with our own special equipment and appropriately qualified professionals. Our greatest strength is our ability to adapt to the individual conditions on the construction sites at any time during the project. Our long-standing experience and a wide range of technical possibilities ensure that implementation is always safe and successful.
