Review on 🔍 Fluorescent Leak Detection Dye - 1 Gallon Concentrated Green Tracing Dye - Enhancing Visibility by Heather Shaw

This product proved conclusively that during a heavy rain, water flowing under my floor from a road draw well long ago found its way out of an apparently broken drain pipe and caused a major collapse on my road. The hole is 40 inches wide and 40 inches deep and extends an unknown distance even under intact asphalt. My city cannot contest the results and will correct the situation and repair my driveway. You can see in the photo that a few minutes after I poured it into a tray on the street in heavy rain, the green paint got into a big hole.
