Our customers experience little loss from these hazards. Our tests and testimonials from our customers indicate little to no damage from street sweepers. A snow plough would be capable of scraping off a marker but they have been used extensively in snowbelt areas and customers report very little to no actual loss. A determined vandal can remove a marker. However in over 20 years, there have been very few reports of actual occurrences exceeding 1-2% of markers applied. The benefits of permanent marking with the drain markers far outweigh the risk of occasional loss or damage to the marker due to any of the above factors.
