New Exposure Limits for Michigan Contractors
OSHA’s revised Respirable Crystalline Silica Standard—effective March 1 2025—lowers the permissible exposure limit to 25 μg/m³ averaged over eight hours for construction work. Demolishing concrete exceeds this threshold without wet‑cutting and local exhaust ventilation. Drilling 2‑inch mudjacking holes also releases dust above the new action level in laboratory tests.
Why Mudjacking Falls Short
Mudjacking crews drill roughly four holes per square yard, generating up to 11 pounds of dry dust during a typical driveway lift. Foam lifting needs just one ⅝‑inch port per slab corner. In most cases we collect dry tailings in a HEPA vacuum so exposure remains below 3 μg/m³. For an external deep dive read Foundation Pros’ overview of mudjacking essentials.
Compliance Strategies We Deploy
We train technicians under OSHA 1926 Subpart CC for silica and provide full‑face PAPR respirators where cutting cannot be avoided. Our resin arrives in sealed drums and remains encapsulated after cure, eliminating dust risk entirely.
Environmental and Customer Benefits
Less drilling means fewer surface patches and a cleaner work site. Homeowners avoid slurry stains and the musty odor of cement grout. Municipal inspectors appreciate that foam lifting keeps fine particles out of storm drains—a growing concern in the Shiawassee River watershed.
