Seal it Tight

Mine Seal Construction for Air Control, Isolation, and Explosion Containment

GMS constructs permanent and temporary mine seals to isolate worked-out areas, control airflow, and meet MSHA explosion resistance standards. Whether built for ventilation control, emergency isolation, or compliance with regulatory plans, our seals are engineered and installed by experienced crews using approved materials and proven construction methods. Each seal is tailored to site-specific conditions and ventilation requirements to ensure long-term performance and safety.
