Concrete grinding uses a diamond disk to remove high spots in concrete. It is perfect for floor leveling prior to tile installation or to remove glue from the previous flooring installs. Municipalities and school districts have depended on us for years to help keep their sidewalks safe with our grinding methods. Precision has recently been hired to grind trip hazards from many kilometers of sidewalk to reduce the chance of someone tripping over a sidewalk panel that has been uplifted by a tree root or frost heave. Our electric grinders can be used indoors or outdoors and can cover many hundreds of square feet in a day.
