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.

Expertise in structural works

Every solution is studied to suit the building, the ground and the surroundings.

A durable, reliable solution

Strengthening works guarantee long-term stability.

Frequently asked questions

When should an existing structure be strengthened?
Strengthening is needed in the event of cracks, settlement, a change of use, or an increase in loads.
Does structural strengthening require demolition?
No. The solutions are designed to preserve as much of the existing structure as possible.
Which parts of the building can be strengthened?
The foundations, floors, load-bearing walls and structural elements can all be involved.
Can a structure be strengthened on an occupied site?
Yes, in many cases, depending on the nature of the works and the safety constraints.
Does strengthening guarantee long-term stability?
Yes — when correctly designed and carried out, it ensures durable stability.
