Advice, diagnostics, services and repair solutions
Our expertise is built on more than 15 years of research and laboratory development, conducted alongside Professor Julius Natterer, a pioneer of modern timber construction.
Founded by Dr. Jean-Luc Sandoz, a wood material expert and author of Civil Engineering Treatise – Volume 23: Building with Wood, our approach combines scientific rigor, field experience, and technological innovation.
With a PhD in wood quality, Jean-Luc Sandoz laid the foundation for an integrated approach linking material characterization, structural diagnostics, and constructive optimization.
This dynamic has led to the development of two internationally recognized tools:
Sylvatest, an ultrasonic technology for the non-destructive evaluation of wood’s mechanical properties,
Polux, a portable device for on-site diagnosis and inspection of wooden utility poles in service.
With thousands of expert assessments carried out in Switzerland and worldwide, we know where to look to detect structural issues and how to identify their root causes, in order to design appropriate, measured, and sustainable solutions.
Our expertise covers the entire life cycle of wooden structures:
Structural diagnostics and in-situ mechanical characterization of wood
Durability assessment and detection of biological degradation
Quality control of new structures and long-term performance monitoring
Restoration and strengthening of existing structures
Technical consulting for owners, architects, and contractors
Training and knowledge transfer on non-destructive methods and responsible design
Legal and technical advisory
Our approach combines fundamental science of wood materials and structures with applied engineering and continuous innovation — to build, diagnose, and restore while preserving the architectural quality of historical buildings.
