Blast holes of any diameter, orientation or depth can be plugged with FOAMPLUG™. FOAMPLUG™ can hold up to 3000 pounds of explosives in breakout holes. FOAMPLUG™ can be used to deck around mud seams or voids or to reduce scaled distance for vibration control. Underground, FOAMPLUG™ can be used as stemming, to retain emulsion in overhand holes or prevent debris infiltration on downholes. It can also be used to trim blast perimeter holes for improved ground control and safety.
