As part of a renovation project in Cagnes-sur-Mer, we successfully enlarged two openings in load-bearing concrete block walls. The first crucial step was to carefully prop the load-bearing walls and the ceiling to guarantee the stability of the site. We then precisely enlarged the existing openings, taking care to preserve the integrity of the walls.
Building reinforced concrete counter-columns was a critical phase to support the extra weight resulting from the enlargement. Each opening was then strengthened with a double beam, wedged with non-shrink mortar to ensure a solid, lasting connection. The double steel beams were joined together with threaded rods passing through them.
After the shoring was dismantled, we cleaned the site thoroughly to remove all debris. In addition, anti-rust paint was applied to the beams to protect them against corrosion, and a fire-resistant casing was fitted around the steel beams to ensure fire safety.
This project, carried out with precision and constant attention to safety, resulted in a significant improvement to the structure while preserving its original look.
