Cast-in-place concrete pile foundations

Cast-in-place rammed piles are full-displacement piles used in special civil engineering to transfer particularly high loads from structures to deeper, load-bearing soil layers.

We supply driven piles as displacement piles in a range of designs:

In-situ concrete driven piles

  • Frankipfahl NG® piles
  • Simplex piles

The piles are driven dynamically, either by internal pipe driving or by head driving, depending on the type of pile. 

Applications

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

  • Industrial buildings
  • Bridges
  • Wind turbines
  • Logistics warehouses
  • Residential and commercial buildings
  • Offices and hotels

Advantages

With their short set-up times, rapid pile production and high load-bearing capacity, driven piles are more cost-efficient and result in shorter construction times. The soil is fully displaced, yielding optimised subsoil conditions and zero drilling waste. This saves on additional costs for transport and landfill disposal.

The installation procedure and the control of the required resistances allow the pile lengths to be readily adapted to changing soil strata.

The advantages of driven piles:

  • Very high pile loads possible
  • Optimum adaptation to subsoil conditions
  • Narrow piles with less concrete consumption and lower carbon footprint than alternative pile systems
  • Full soil displacement, thus no transport or disposal costs for the drilling waste
  • Complication-free use in contaminated soils
  • Economical pile system due to high pile production output
  • Very good resistance-settlement properties
  • Plumb and raking piles can be installed at an inclination of up to 4:1
  • Can be designed as an energy pile, so that the driven piles can also be used for geothermal purposes.

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

Quality assurance in construction work requires compliance with European and national standards and the recommendations of the "Piles" working group (EA-Pfähle). The self-monitoring and documentation of construction execution are also regulated in manufacturing standards.

A procedure instruction that is individually adapted to the requirements of the relevant project is required to install driven piles. The machine operator’s instincts are just as important as their technical knowledge or experience. Operating the large special equipment is a delicate process that requires optimal tuning of the manufacturing parameters to achieve the desired pile resistance.

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
  • Pile integrity tests

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.
