Pumpable Tower Cribs

Stacked for Strength

Pumpable Tower Cribs for Longwall Tailgates and Soft Ground Conditions

GMS pumpable tower cribs provide high-capacity, yieldable ground support in mines where tall, stable structures are required. Ideal for soft floor and poor roof conditions, these cribs are used in tailgate entries, recovery zones, and other high-convergence areas. Designed for both strength and efficiency, tower cribs are fabricated in stackable sections and filled on-site with two-part grout to match the mine’s loading and height requirements.
