Understand the Cause of the Rust Stain

What happens here

Based on the video, rust stains on patio pavers, particularly those from manufacturers like Unilock, are often caused by small pieces of metal or aggregates with metallic content becoming embedded in the paver during manufacturing or installation. Over time, exposure to moisture causes these metallic inclusions to oxidize, resulting in visible rust stains on the paver surface. Understanding this common cause helps in discussions with the paver manufacturer or installer, demonstrating a clear understanding of the issue.
