The PCC Difference
Wet Grinding:
Better For the Environment, Better for All
Every polishing contractor is different, but we utilize a wet grinding system. Dry grinding systems produce a large amount of concrete dust, which contains crystalline silica. OSHA has recently released information regarding the potential health effects crystalline silica has if inhaled in large amounts, which include the "development of disabling and sometimes fatal lung diseases, including silicosis and lung cancer." Read more about the dangers of crystalline silica on OSHA's website. Airborne silica is not only a concern on an active installation site, but because dry grinding creates such a fine dust, it can settle into ventilation systems and remain in the building for years.
Dry griding systems do have dust extractor systems built in, which equipment manufacturers claim to contan 99% of airborne dust. We’ve found them to be of limited use. So we perform our grinding steps, which produce the majority of the concrete waste, wet using only water. We contain the slurry (a liquid or paste that forms when concrete dust mixes with water) and place it in an on-site concrete washout. Once the slurry dries and rehardens to a concrete state, the concrete is then recycled. A little extra cost, a little extra work, but a huge benefit for everyone and the environment.
CONCRETE POLISHING​
Concrete polishing is a proven, eco-friendly flooring solution that combines durability with modern aesthetics. Using an existing concrete slab—often the building’s foundation—we transform it into a smooth, decorative surface with a clean, refined finish. The result closely resembles polished stone, such as granite or slate, while maintaining the natural character of the concrete.
​
Throughout the polishing process, we use products designed to enhance and strengthen the concrete rather than cover or alter it. This preserves the slab’s natural integrity while improving its density, durability, and resistance to stains and wear. The finished floor offers a long-lasting, low-maintenance surface that performs as well as it looks.
THE PROCESS OF POLISHING CONCRETE
The concrete polishing process is similar to sanding wood, but on a much larger scale. It begins with coarse grinding to remove dirt, coatings, and surface imperfections while exposing the stronger concrete beneath. From there, progressively finer grits are used to refine the surface, creating a smooth, flat, and level floor ready for polishing.
​
In the final stages, high-grit resin diamonds bring the concrete to the desired finish, whether a high-gloss shine or a more subtle, low-gloss look. Along the way, a densifier is applied to strengthen the concrete and improve abrasion resistance, followed by a penetrating sealer that helps protect against staining. The result is a durable, low-maintenance floor built for long-term performance.
SUSTAINABILITY
Concrete polishing has become one of the leading flooring options for environmentally conscious architects, owners, and builders, and a top flooring option for LEED accredited projects. Its green benefits include:
-
All products meet or exceed LEED VOC content requirements
-
Uses the original building foundation – no excess materials, nothing to remove
-
No environmentally hazardous coatings, toppings or adhesives
-
No harsh chemicals can be used for cleaning – only green, PH neutral soaps and/or water
-
Increases ambient light reflectivity – reduces necessary amount of lighting and electricity use
-
25+ year life expectancy with proper care and maintenance
