We are manufacturer of hydraulically expandable friction bolts GEOSTABIL for strata stabilization and reinforcement in underground mining. Our GS bolts are suitable for areas with high stress and deformation and can be pre-tensioned and or injected.

Unique design of expansion bolt (patented) allows us to produce bolts of different ultimate and shear load capacity. Bolts of right size, strength and capacity are essential for efficient reinforcement of strata resulting in safe working environment.
