Passive Shoring

Transfer of transient loads during a repair, a bearing replacement or an intervention beneath a load-carrying element. The governing design criterion is settlement: a support that gives by a few millimetres transfers the load elsewhere.

  • Transfer of transient loads
  • Light frame unloading

Jacking Procedures

We set the load-application stages, design the temporary substructure that receives the jacks — corbels, posts, spread footings — and write the lifting steps your crew will follow. The jack is chosen with you, and we stay with you throughout the project.

  • Staged load application on the jacks
  • Design of the temporary substructure (corbels, posts, etc.)
  • Safety measures and lifting steps

Active Jacking

Bridges and structures, building frames, heavy equipment. Hydraulic jacks for short travel, cranes when the stroke demands it.

  • Lifting of various structures
  • Bridges / civil structures
  • Building frames
  • Heavy equipment
  • Short travel (hydraulic jack)
  • Long travel (cranes)
