Simplex piles

Displacement pile in accordance with DIN EN 12 699

Simplex piles are cost-effective in-situ concrete driven piles. They can be used as a deep foundation element for all types of structures. Using Simplex piles improves the subsoil by fully displacing the soil instead of extracting it. This also saves on additional costs for transport and landfill disposal.

One of the most persuasive features of the Simplex pile is its short production time. Under suitable conditions, it is particularly effective when used  for foundations with a large number of piles and predetermined long embedment lengths in load-bearing subsoil.

Simplex piles (only available in German)


Simplex piles can be used as deep foundation elements for every type of structure. These include:

  • Logistics warehouses
  • Industrial buildings
  • Wind turbines
  • Silos
  • High-bay warehouses
  • Crane tracks
  • Heavy load areas


This pile system is particularly suitable for projects with a large quantity of piles and long pile lengths. Simplex piles are used where the noise emissions caused by head driving are not a critical factor.

  • Very high daily output and thus rapid construction progress
  • High pile loads possible: Characteristic pile resistances Rk of up to 6,000kN
  • Full soil displacement, thus avoiding the need to transport excavated soil and saving costs
  • Very economical system due to savings in concrete and steel
  • Good resistance-settlement properties
  • Can be used on contaminated sites
  • Also available as an energy pile

Basic facts

Standards and regulations

Simplex piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12699 and the recommendations of the “Piles” working group (EA-Pfähle). Diameters range from 42cm to 61cm. Pile lengths of up to 40m are possible. 


Simplex piles are in-situ concrete driven piles with a reclaimed driving tube. This is sealed from below with a watertight base-plate. The pipe is driven into the ground by a hydraulic hammer via the head. The driving work involved, measured in blows per metre, is a measure of the load-bearing capacity of the soil at the pile site in question. Once the desired depth is reached or the driving criteria are met, a reinforcement cage is installed, concrete is poured in and the casing tube is retracted.

Quality assurance

The requirements of the relevant European and national standards must be observed to ensure quality assurance during construction. Our Simplex 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). Self-monitoring and documentation of construction are regulated in the manufacturing standards.

A procedure instruction that is individually adapted to the requirements of the relevant project is required to install Simplex piles. The machine operator’s instincts are just as important as his 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 via our quality management system in accordance with DIN EN 9001:2015
  • Static or dynamic pile load testing
  • Pile integrity tests
