Baroid Benseal® and EZ-Mud® Slurry

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.

    The use of BENSEAL and EZ-MUD slurry assists or promotes the following:
  • 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


  • 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
  • Pumps at reduced pressure
  • No heat of hydration
  • Easy to mix
  • Re-hydratable
  • Minimal grout level subsidence
  • Allows hole reentry
  • Both products are NSF/ANSI Standard 60 certified
