Diamond-polished concrete floors
Diamond-polished concrete is one of the leading options for enhancing beauty, lowering maintenance and energy costs, all while retaining the natural beauty and slip-resistance of concrete. Polished concrete is a proven leader in Green Building and LEED Certification.
Aside from concrete floors with structural damage, polished concrete is a cost-effective, viable option for virtually any concrete floor. You can find polished concrete in every kind of building from homes to shopping centers, and manufacturing facilities to clean-room laboratories and medical centers which require dust-free environments.
Diamond-polished concrete's cost of ownership is significantly lower than vinyl, carpet, and other "stick-on" flooring.
Designer colors and precise saw cuts may be added to polished concrete to meet the most demanding aesthetic requirements. And, with a little bit of low-cost care, you can expect most diamond-polished concrete floors to deliver decades of service.
Much like finishing a fine piece of wood, diamond-polished concrete floors are made smooth and shiny through a series of polishing phases.
The process begins by removing any foreign materials, such as adhesives from the floor, repairing cracks, and other mechanical or cosmetic imperfections.
The polishing begins with coarse diamonds (16 - 20 grit) gradually moving to very fine diamonds (1,500 - 3,000 grit), The MJA Company smooths and polishes away any foreign materials and roughness that is found in natural concrete or existing concrete that may have adhesives or other contaminates on the surface. As the process continues to the fine diamonds, the level of gloss increases.
The MJA Company will diamond-polish the floor to your specifications and deliver the level of smoothness and gloss that you prefer.
During this process, special chemicals are used to harden and densify to concrete surface. This integrated sealer becomes a permanent part of the concrete, thus eliminating the need for additional sealers, polishes or waxes.
Until recently, diamond polished concrete required water to prevent the resin-bonded diamonds from friction overheating during the polishing process and to keep the concrete dust from filling the room. The slurry created by the water and concrete dust had to be collected and disposed of in an environmentally responsible way. This lead to more labor hours and higher costs.
Now, dry polishing technology collects the concrete dust, eliminating most of the cleanup process. In rare cases, some water may be used in the final fine polishing phase, but the use of water is limited and cleanup is not a major issue.
Advantages of Polished Concrete Floors
Diamond polished concrete eliminates concrete dusting that is common in unpolished floors. The result is less cleaning, lower maintenance cost and cleaner rooms from floor to ceiling. This is especially important in rooms that contain electronic and other devices that can sustain damage in dusty environments.
Diamond polishing "tightens" the concrete surface, making them less porous and naturally resistant to the leading causes of concrete floor failure: moisture and chemical intrusion.
Unlike concrete coatings that lay on the surface of the floor and wear away over time, the chemicals used in the polishing process penetrate the surface of the concrete and create a permanent increase in strength. This "concrete densification" and increased strength are more resistant to abrasion, impact, and marking.
When properly maintained, diamond polished concrete floors not only retain the natural slip resistance of concrete, the lack of dusting of polished concrete actually increases the coefficient of friction that can be compromised by the presence of dust and debris.
Whether wet or dry, properly polished concrete floors, done with the proper chemicals can be certified as "High-Traction" floors by the National Floor Safety Institute (NFSI).
► Slip resistance is of prime importance to The MJA Company. We are New York's only Western New York’s only ANSI accredited WACH (Walkway Auditor Certificate Holder) with extensive training and certification from the National Floor Safety Institute (NFSI).
Extensive training, testing, and measurement equipment is required for NFSI certification. All polished concrete floor projects by The MJA Company conform to the ANSI B101.0.2012 National Floor Safety Institute's rigorous standards.
