The BENSEAL and EZ-MUD slurry combines two widely used Baroid products into a patented technique that provides a simple, economical method to seal and grout boreholes, well casings and earthen structures. The slurry develops a high quality grout with low permeability. 

Applications and Functions

  • Seal or grout plastic and steel casings 
  • Seal downhole instrumentation in test and observation holes 
  • Plug abandoned boreholes for mineral, water and seismic exploration 
  • Stabilize broken or unconsolidated formations 
  • Grout ground source heat pump loops


  • Both products are NSF/ANSI/CAN Standard 60 certified 
  • Develops strong bond between grout, casing and formation 
  • Forms a flexible seal with a very low permeability that prevents commingling of aquifers and entry of surface contaminants 
  • Delays bentonite swelling on surface so that unyielded bentonite will swell in situ
  • No heat of hydration 
  • Re-hydratable 
  • Minimal grout level subsidence 
  • Allows hole reentry
