Commercial Concrete Floor Levelling & Surface Restoration

Commercial Concrete Floor Levelling & Surface Restoration

Before the restoration, the concrete substrate presented several operational and safety hazards:

• Severe Surface Undulation: Pronounced ridges and uneven patches made the floor unusable for forklift traffic and thin-set coatings.

• Weak Laitance Layer: The top surface was dusty and degraded, requiring deep mechanical removal to expose the sound concrete beneath.

• Enclosed Space Constraints: Being an indoor project, traditional dry grinding was impossible due to strict dust control and air quality regulations.

The Solution:

Step 1: Environmental Dust-Free System Coupling

Before initiating any mechanical grinding, our operators securely connected the CMG-350 to a heavy-duty industrial vacuum unit. By utilizing the machine’s built-in floating dust shroud, a tightly sealed negative-pressure environment was created around the grinding head. This containment system successfully captured 99% of airborne concrete dust directly at the point of origin, allowing other site trades to work nearby without disruption.

Step 2: Aggressive Ridge Reduction & Levelling

Our crew executed a systematic, overlapping cross-hatch grinding pattern across the entire designated area.

• Thanks to the CMG-350’s optimized operating weight of 95 KG, the diamond segments achieved an aggressive, consistent bite into the high spots of the hard concrete without requiring any external counterweights.

• The balanced, dual-wheel chassis design allowed the operator to glide smoothly over uneven transitions, shaving down the harsh ridges while preventing any accidental gouging of the floor.

Step 3: Concrete Pore Opening & Profile Finalization

The high-torque single-disc setup effectively stripped away the weak laitance layer and opened up the tight concrete pores. This process successfully transformed the slick, contaminated surface into a uniform, textured Concrete Surface Profile (CSP), which is mathematically required to create a permanent mechanical bond for future epoxies, sealers, or self-levelling compounds.

Conclusion:

• 100% Level Surface Achieved: All major concrete humps, rough ridges, and unlevel joints were completely flattened, restoring total structural flatness to the floor.

• Zero Dust Contamination: The tightly shrouded vacuum integration kept the workspace exceptionally clean, fully complying with indoor occupational health and safety standards.

• Optimized Coating Ready Base: By removing the laitance and opening up the concrete pores, the floor achieved an ideal mechanical anchor profile. This will drastically reduce the client's material consumption for any subsequent epoxy topcoats.
