Pressure Grouting:



  • Roof stabilization for underground mines
  • Pre-grouting for vent shafts
  • Stabilizes large diameter borehole walls to allow for shaft completion
  • Sealing of water bearing formations
  • Formation stabilization (filling the voids in fractured formations)
  • Increase shaft longevity

We have the ability to drill pre-grouting boreholes for mines that are installing large diameter ventilation and access boreholes. RACS has the ability to drill a hole and cement through packers on a 24 hour basis thereby minimizing standby for the client and shortening overall project length and expense. Our company can provide expert advice and technical assistance for all pressure grouting applications. Depending on your requirements and the results of testing we can mix and pump standard cements, fine grind and chemical grouts.
