Concrete grinding creates a massive amount of "Silica Dust," which is a known respiratory hazard and a nightmare for homeowners to clean. Most Florida garage floor companies use a standard shop-vac that simply blows the fine dust back into your garage and through your HVAC system. At OtterTek, we use the "Lungs"—a medical-grade, HEPA-certified vacuum system that creates a sealed environment between the grinder and the dust bin.
