Concrete grinding or sidewalk cement grinding is one method to remove sidewalk trip hazards typically up to 1 1/2″ in height where sidewalks have been lifted by tree roots, shifting soil, etc. Concrete grinding will remove the top finished layer of cement and leave an exposed aggregate finish where the concrete trip area has been removed, but ...
Polishing Process The process begins with the use of coarse diamond segments bonded in a metallic matrix. These segments are coarse enough to remove minor pits, blemishes, stains, or light coatings from the floor in preparation for final smoothing. Depending on the condition of the concrete, this initial rough grinding is generally a three- to four-step process.
Aug 30, 2012 · Cement is the basic ingredient of construction and the most widely used construction material.
