GERB SA, the French subsidiary of the German GERB group has been founded in 1979 in St. Nazaire at the Atlantic Ocean. At the same time this was the first company established outside of Germany, mainly with the purpose to participate in the developing market for the French Nuclear Power Plants.

These days more than 34 staff work in the sales office in Marly le Roi/Paris as well as the production facility in St. Nazaire. The areas of activities have widened and include today applications in the industry, in building isolation and acoustical solutions.


Main areas of activities:

• Own engineering office for design and construction of various types of foundations
• Statical and dynamical calculations, as well as taking care of projects from the initial design to the final erection and acceptance of the foundation.
• Measurements for vibration -, structure-borne noise - and noise control

Building isolation
GERB SA has very successfully supported a large number of well-known buildings in France on spring elements:

• Hotel SHERATON at ROISSY Charles de Gaulle International Airport, 25.000 t
• Le Corum, Concert hall of the Opera Montpellier, 23.000 t
• Passage du Havre, apartment- and office building in Paris, 34.000 t

Floating Floor
In 1991 GERB SA has been granted a patent for spring supported Floating Floors, using PF elements. Up till today more than 90 projects with more than 15,000 PF spring elements have been completed. These Floating Floors are applied especially in cinemas and concert halls, some of our references are:

• Casa Fouquet's, Discotheque in Paris, active isolation with 218 spring elements
• HILTON Hotel, Lyon, active isolation with more than 500 spring elements

as well as:
