Independent building expert

Expertise subsidence

Expertise collapses & settlements

Your house is moving? Act fast

Doors and windows that close badly, staircase cracks on the walls, floor that bows, tile that cracks... These signs often reveal a landslide or a settlement of foundations. And contrary to the ideas received, it is not restricted to old houses: recent buildings may also be affected, especially on clay soil or poorly prepared.

The danger? The stability of the structure is at stake. An untreated settlement can evolve towards a generalized collapse, weakening the structure and endangering the safety of occupants.

Our expertise assesses the seriousness of the situation and determines the appropriate solutions.

Warning signs

Staircase cracks

Typical differential settlements. They follow masonry joints.

Cornering doors and windows

The building is deformed, the openings are no longer square.

Land that bows

Sensation of slope inside, rolling balls, furniture that bend.

Separation between elements

Deceleration between walls and ceiling, between extension and main building.

Corner cracks

Areas of weakness where movements are concentrated.

Frequent causes

Nature of the soil

Clayy soil (swelling/weakness depending on moisture), poorly compacted embankments, underground voids.

Drought

The soil retracts, the foundations are no longer supported evenly.

Water infiltrations

Pipe leaks, lack of drainage: water weakens the terrain.

Overload

Extension, attic layout, addition of floor: undersized foundations.

Nearby work

Terrace, nearby construction, underground work: vibrations and ground movements.

Our method of analysis

1. Full inspection

Condition of foundations (if accessible), crack analysis, measurement of deformations, verification of carrier structure.

2. Context analysis

Soil nature (if geotechnical study available), building history, recent work, water presence.

3. Gravity assessment

Stabilized or evolutionary? immediate danger or situation to be monitored?

5. Option: Installation of crack tell-tales

To monitor the evolution over several months (+100 € tax excl./control).

What our customers like

Structural expertise: we know the pathologies of the building

Gravity assessment: we do not dramatize or minimize

Adapted technical solutions: recovery, micropious, injection...

Third party report: usable for insurance, work or judicial expertise

FAQ

Yes. Even minimal, it gradually degrades materials, damages health and loses heritage value.

Not without identifying the cause. Otherwise, you spend money for nothing and the problem comes back.

This depends on the cause: from a few hundred euros (roof repair) to several thousand (drainage, vultures, injection).

Does your house show signs of collapse?

Don't let the situation get worse.
