Recent developments in support of tailgates in Longwall panels have led Sub-Technical to develop a system and materials to cost effectively install these pumpable cementitous cribs.

Pumping is performed at the surface using automated batch control and bulk material storage. The material is pumped down a borehole then horizontally to the crib site where bags of 24-inch, or 30-inch diameter are pumped in place.

Recent tests at NIOSH test center have revealed material strengths up to 1,500 P.S.I. comprehensive strength. Please call to discuss how Sub-Technical can save you time and money in your tailgate.
