We remove trip hazards from concrete and asphalt sidewalks to alleviate trip and fall liability and improve walkability in communities. Our approach has been awarded seven U.S. patents. We use a horizontal saw to repair trip hazards as small as 1/4 inch to as high as 2.5 inches.  Municipalities find that our proprietary service is more efficient and costs just 15-20% of the cost of conventional methods of trip hazard removal.
