Concrete Settings

We've found that concrete demands initial low-power passes in laser cleaning to avoid aggregate spalling, a risk not as prevalent in denser stones like granite. Its inherent porosity allows effective absorption of laser energy, which reveals embedded contaminants without excessive heat buildup. We typically follow with multiple overlapping scans to restore surface uniformity in infrastructure settings, reducing the chance of uneven ablation.
