Strengthening of existing structures — securing and future-proofing your building
Specialists in structural strengthening for existing buildings.
Strengthening an existing structure consolidates a building when its structure is no longer suited to the loads, the use or the condition of the ground. Sirianni Travaux works on both old and recent structures, for private and professional clients, with reliable, well-mastered technical solutions.
Consolidate without demolishing
What is structural strengthening?
Strengthening an existing structure improves the bearing capacity and stability of a building without altering its overall architecture. It is typically carried out during renovations, extensions, changes of use, or following structural disorders.
Depending on the site constraints, strengthening may involve the foundations, floors, load-bearing walls or the structure as a whole, using suitable, durable solutions. These are targeted works, designed to suit the existing structure, the loads to be taken up and the ground constraints.
Why strengthen an existing structure?
Structural strengthening ensures the durability of a building in the face of current and future demands.
Secure an existing building
Strengthening reduces the risk of settlement or weakening.
Adapt the structure to new loads
It allows extensions or changes of use to be accommodated.
Correct structural disorders
Strengthening addresses existing cracks, deformations and weaknesses.
Preserve what already exists
The works avoid a complete demolition of the structure.
