Thin Spray Liners

Thin Spray Liners for Surface Stabilization, Dust Suppression, and Airflow Control

GMS applies thin spray liners (TSLs) to reinforce exposed surfaces, reduce air leakage, and improve ground control in underground mining operations. These spray-on coatings form a durable membrane over ribs, backs, or stoppings, sealing cracks and fractures while minimizing dust and air loss. TSLs are a fast, effective solution for sites requiring added support or sealing without the time and labor of structural construction.
