Défis du RGA (Retrait-Gonflement des Argiles) pour les Bureaux d’Études

CAS D'ETUDE



Cracks in facade walls may seem minor, but without careful monitoring, they can worsen and lead to major structural issues. Regular monitoring and prompt intervention help prevent significant damage and ensure the building’s safety.

Neglecting Cracks Involves Several Risks:

  • Worsening damage
  • Higher repair costs
  • Loss of effective corrective solutions
  • Compromised building safety

Common Causes of Cracks


Cracks can appear for various reasons, including:

  • Ground movements (shrink-swell of clays, subsidence, differential settlement)
  • Climatic variations (drought and heavy rain cycles, freeze-thaw effects)
  • Construction errors (incorrect reinforcement placement, improper sizing)
  • Material aging and wear over time

Identifying the underlying cause is essential to applying the right solutions and preventing cracks from reappearing after repairs.

Regular crack monitoring, combined with an analysis of potential new deterioration, helps anticipate problems and minimize risks.


The Importance of Continuous Crack Monitoring


Continuous crack monitoring is essential to prevent structural damage. Over time, a crack may widen, weakening the structure and increasing the risk of water infiltration or partial failure of load-bearing elements.

Crack monitoring sensors, such as those from the Deltafeel range, measure and record crack evolution in real time.

With this technology, building owners and industry professionals can detect structural movements and intervene before problems worsen.

Feelbat sensors are designed for use on various types of structures:

  • Facade walls
  • Historical monuments
  • Bridges and civil engineering structures
  • Mega-structures

Feelbat Solutions for Crack Monitoring


Feelbat is a leader in structural monitoring and showcased its solutions at VivaTech 2023. Its sensors are designed to detect the slightest crack movements: size variations, inclination, misalignment, and deformations.

These devices provide real-time, precise data, accessible via a mobile app and web platform, making diagnostics and maintenance decision-making easier.

Continuous crack monitoring with Feelbat sensors allows for:

  • Anticipating major issues before they compromise the structure
  • Reducing repair costs by avoiding heavy interventions
  • Extending the lifespan of the building through efficient maintenance

Conclusion


Regular crack monitoring is a crucial part of infrastructure management and maintenance.

Feelbat's structural monitoring sensors offer an effective and intuitive solution to detect even the smallest movements and ensure proactive prevention against structural risks.

Rigorous monitoring helps avoid costly repairs and preserves the safety of occupants and infrastructures. Feelbat supports professionals and asset managers by providing innovative solutions tailored to every need.
