Perform grinding and texturing using diamond blades mounted on a self propelled machine that has been designed for grinding and texturing concrete surfaces. Ensure the equipment will not cause strain or damage to the underlying pavement. 2. Do not use grinding and texturing equipment that causes excessive ravels, aggregate fractures, spalls, or ...

Diamond grinding removes a thin layer from paved surfaces, producing a grooved surface with superior wear tolerance, longevity, and surface friction. The process of diamond grinding requires that a thin layer of hardened concrete and asphalt pavement at the surface be removed with diamond saw blades.

Diamond grinding (DG) removes a thin layer at the surface of hardened PCC pavement using closely spaced diamond blades. DG used to be an expensive operation; however, new, high-production equipment as well as improved synthetic diamonds for saw blades made DG a more cost competitive option for PCC pavement rehabilitation.

Figure 257.A – Types of Diamond Grinding Equipment . Figure 257.B – Types of Diamond Grinding Equipment. Equipment requirements for diamond grinding: § Must be a power driven, self-propelled machine, specifically designed to smooth and texture Portland cement concrete pavement with diamond blades or diamond impregnated cylinder rings.

Concrete grinding can save you hundreds or thousands of dollars over a complete surface replacement.With the right grinding equipment, it's possible to take on just about any job, from sanding a small hump in the cement to excavating a 1" trench hundreds of feet long. Floor Grinding Cement floors are never completely smooth and level.

Concrete diamond grinding removes roadway imperfections caused by construction and/or heavy usage. The immediate result is an improvement in pavement smoothness, surface texture, skid resistance, safety, and noise reduction. This service can also be applied to asphalt pavement. Advantages of diamond grinding over other rehabilitation techniques:

Equipment Inspections .
