Conservationists working to restore the historic Al-Hadba Minaret in Mosul have successfully deployed ‘Acoustic Holography’ to identify critical structural vulnerabilities. This non-invasive technology uses sound wave reflections to create high-resolution 3D maps of the interior masonry, revealing hidden fissures and voids within the 12th-century brickwork that are invisible to traditional X-ray or LiDAR scans.
The data collected will allow engineers to perform precision reinforcement, injecting specialized bio-lime grouts exactly where the structure is weakest without disturbing the historic exterior. This breakthrough represents a significant advancement in heritage preservation technology, providing a safer method for stabilizing leaning or damaged monuments in post-conflict zones.
