WISIS : structural wood inspection device

Industrial and field analysis equipment Software and digital applications Natural resources and territories
WISIS is a non-destructive inspection device for structural wood elements, including poles and standing trees. Portable, it is used by infrastructure maintenance services and wood structure providers as part of maintenance contracts. It helps predict risks of damage to users, enabling preventive action.

A tool for detecting non-visible deterioration in structural wood

Wood is widely used in construction applications. Excessive loads, fungi or insects can degrade wood elements in service. The WISIS system enables the condition of structural wood to be assessed using a non-destructive method, in order to detect potential deterioration and anticipate repairs of damaged components.

As some forms of deterioration are internal and therefore not visible to the naked eye, WISIS relies on changes in the propagation of elastic waves when wood degradation is present.

Key advantages of WISIS

The WISIS inspection device is a field tool that :

  • is portable and compact;
  • delivers fast and reliable results;
  • features a simplified graphical interface for ease of use;
  • includes a fast acquisition board powered directly via the computer’s USB port;
  • provides automatic parameter settings for the acquisition system;
  • is available in French and English;
  • offers potential for the development of customised applications.

A valuable tool for maintenance and safety inspection services

WISIS is a high-performance inspection tool tailored to the needs of infrastructure maintenance services and organisations responsible for safety and compliance of structures and installations. Its use helps reduce the risk of damage related to the deterioration of wooden components. It also contributes to effective implementation of HACCP procedures in organisations using wood.
