Methods

How special civil engineering works.

We are the technology leader in special civil engineering and a competent partner in all phases of the construction project. To illustrate our services, you will find important information here on our diverse procedures in all service areas of foundation engineering.   

For selected procedures, our explanatory videos are available in a short and a long version. You can currently find an explanatory video for the atlas pile, soil mixing method, jet grouting, Frankipile NG®, micro pile, diaphragm walls, grouted anchors and soft gel injections.

Economical and safe on any subsoil: this is how special civil engineering works.

We have the appropriate special civil engineering method for your construction project:

  • Consulting, planning and construction from a single source
  • Individual optimal solutions
  • Economical and safe
