Concrete Grinding, Polishing & Staining


Concrete Grinding
Is done using a planetary grinding machine, powered by three phase electric, along with a large heppa vacuum, to eliminate any airborne dust particles. The diamond metal bond tools remove the top layer of the concrete surface.

Applications for Grinding:
1)Remove coatings, mastic, and glue
2)Repair damaged slabs, i.e. rain damage, surface delaminated, flatten high spots, uneven joints
3)Leaves a micro profile ideal for new coating or polish

Polished Concrete
Is one of the most innovative and economical options available today. Polished concrete flooring is used in warehouse, retail and decorative facilities. From showrooms to industrial plants, government buildings to retail facilities, dry polished concrete floors are quickly becoming the fastest growing choice to ever hit the industry.

Concrete Polishing is done using the same planetary grinding machine after the initial grinding is done. Using industrial diamond resin pads of different grits, along with an impregnating liquid silicate hardener, to polish and seal the floor from within the interior of the floor surface. The benefits are listed below:

Elimination of Dusting from Efflorescence
In ordinary unpolished concrete, tiny particles of dust are pushed to the surface through an upward force called hydrostatic pressure, resulting in efflorescene. Efflorescene leads to dusting, which forces epoxies off of the surface of concrete floors, and can make maintenance a costly priority.

Stain-Resistant
By densifying and sealing the surface, polished concrete transforms a porous concrete floor into a tightened floor that is dense enough to repel water, oil, and other contaminants, preventing them from penetrating the surface.

Improved Reflectivity and Ambient Lighting
The reflective properties of a polished concrete floor increases the lighting in facilities. Increased ambient lighting will reduce the energy bill as well as look beautiful.

Increased Slip Resistance
Polished concrete, though quite shiny, does not create a slippery floor. In fact, the benefits of mechanically grinding and flattening the floor will increase the coefficient of friction when compared to ordinary concrete. Polished concrete often exceeds OSHA standards for floors. (ASTM C 1028)

Less Maintenance
Most floor systems, including tile and linoleum, require aggressive scrubbing to maintain a clean environment and nice appearance. Polished concrete surfaces are tightly compacted, reducing stains, and do not require any waxing or stripping to maintain the sheen.

Cost-Effective
Polished concrete will reduce energy and maintenance costs significantly through reflectivity and ambient lighting, reduction in upkeep (such as waxing), and reduced tire wear.

LEED Friendly
Polished concrete not only utilizes existing concrete surfaces, eliminating additional materials such as coverings/coatings and moving towards sustainable building, it typically contains no noticeable VOC's, making it friendly for any USBGC LEED project.

Improved Condition for Old Floors (Mechanical Polish Only)
As concrete ages, surface stress, delamination, curled cold joints, and other problems can arise. Mechanically grinding the floor will remove the top surface of the old concrete and polishing will then strengthen it, increasing it's impact and abrasion resistance.

Reduced Tire Wear (Mechanical Polish)
The rough, uneven texture of natural concrete causes tires to abrade, adding to their wear. A polished concrete floor system will level the joints and make the entire surface smooth, preventing this abrasion.

No Production/Plant Shutdowns (Dry-Polish Mechanical)
Dry-Mechanically polished concrete can be put into service immediately after the process is complete. Due to the cleanliness of the process and the lack of toxic or hazardous chemicals, floors can often be serviced while the plant is in full production.

Concrete Staining
Stains or dyes may be applied to cover the surface. When applied after grinding. the product will penetrate deeply into the surface. The liquid lithium densifier will lock in the color, and then the surface can be polished to the desired sheen finish.
