We drill a small hole in the sunken sidewalk pad and pump in an environmentally friendly material to stabilize the subgrade and raise the pad to the proper height. This alleviates trip hazards caused by tree roots without damaging the tree or landscaping. Our sidewalk leveling method is superior to grinding, sawing, cutting, or removal and replacement because it addresses the underlying issues, produces less waste and noise, and results in a more aesthetically pleasing and long-lasting fix.
