The France 3 report
The report broadcast on France 3 presents both the phenomenon of clay shrink-swell subsidence and a concrete solution implemented at a homeowner's property.

A subject recognized at the national level
Clay shrink-swell subsidence is the second most costly natural disaster in France, after flooding. Yet it often remains unknown to homeowners — until the first cracks appear on the walls.
The fact that a national channel like France 3 devotes a crack report to this phenomenon reflects the scale of the problem. And the choice to highlight TerraStab as a concrete response is no accident. To learn more about the phenomenon itself, check out our complete guide to clay shrink-swell subsidence.
TerraStab: an innovative solution against RGA-related cracks
Where conventional solutions involve heavy, costly works, TerraStab has developed a different approach: continuously regulating soil moisture to prevent the shrink-swell cycles that cause cracks.
The system relies on connected sensors buried in the soil, which measure water content in real time at different depths. An algorithm predicts at-risk periods, and subsurface irrigation keeps the soil within a stable range — with no masonry works, no micropiles, no demolition.
TerraStab in the field
Every installation is carried out by TerraStab's teams directly at the homeowner's property. Sensors are installed, the system is configured according to the soil type and the home's situation, then monitored remotely via a dedicated platform.
That's what the report shows: a cracked home, a homeowner facing a concrete problem, and an installation that blends discreetly into the garden without disrupting daily life. Discover how TerraStab's soil moisture stabilization solution works.
Why this report matters
It confirms national recognition of a phenomenon long underestimated. It shows that a concrete, accessible solution exists — at a real homeowner's property. It illustrates that RGA is not inevitable.
