Concrete Shaving

Bluegrass has a track record of delivering performance and reliability to decommissioning and decontamination projects in nuclear and industrial facilities by deploying specialized concrete shaving equipment.

What is Concrete Shaving?

 

Concrete shaving is a process which quickly and efficiently removes the surface of contaminated floors, ceilings and walls by shaving off layers to a pre-determined depth leaving a polished surface. Separation of the contaminated surface from the bulk of the concrete significantly reduces the volume of material required to be treated as waste, as the remaining bulk then can be considered contamination free and removed using conventional methods.

Is Diamond Concrete Shaving Safe?

The performance of diamond concrete shaving technology is the safest solution for decontamination jobs. It limits the spread of contamination by containing dust using HEPA vacuum technology, it reduces waste volume by efficiently removing the contaminated layer, and its remote deployment capabilities remove operators from hazardous conditions.

The Marcrist Concrete Shaver

Concrete Floor Shaver: Bluegrass uses the Marcrist Concrete Shaver for use on contaminated concrete slab. The heart of the system is Marcrists uniquely designed, and patented, interlocking surface shaving diamond blades. This system enables the blades to produce a completely smooth surface that is easily surveyed.

Bluegrass concrete shaver operators walk behind the self-propelled unit which shaves a 10” path and uses HEPA vacuum technology to ensure a dust-free environment.

Bluegrass recommends this technology’s ganged diamond blade cutting head as a best practices solution for contaminated ceilings, walls and floors.

Concrete Shaving vs. Scabbling

Decommissioning contractors prefer concrete shaving over concrete scabbling as a superior method. Scabbling is the method of removing the top layers of contaminated concrete with a chipping and hammering machine. One problem with the scabbling systems is more material than necessary must be removed to eliminate the possibility of high spots (i.e. protruding aggregate) thus producing several times more secondary waste than necessary which then must be contained at source and later stored. Another problem with the scabbling method is the quantity of dust produced which must also be controlled and contained.
