For the Arlon 53 project, a large-scale renovation and redevelopment of an office building in the heart of Brussels’ Leopold District, SANACON was commissioned to conduct an in-depth technical investigation of the existing concrete structure. The goal was to validate the current quality of the concrete and determine its remaining lifespan with a view to a circular reuse strategy.
Our approach:
Structural Screening: Performing a detailed condition assessment of the load-bearing concrete columns, beams, and floor slabs.
Corrosion investigation: Analysis of the carbonation depth and chloride penetration to test the active protection of the reinforcement against current standards.
Laboratory analysis: Performance of compression tests on concrete cores to determine the actual mechanical strength of the structure, which was essential for the stability calculations of the new layout.
Result: SANACON’s objective data enabled the project team to make informed decisions about preserving the existing structure. By scientifically demonstrating that the concrete structure was suitable for reuse, significant CO2 emissions were saved, perfectly aligning with the sustainability ambitions of this prestigious Brussels project.
