Bore Drill P

Bore Drill P stabilizing agent is a free flowing, water-soluble, easy mixing, 100% active, dry granular polymer. Bore Drill P stabilizing agent is a very high molecular weight partially hydrolyzed polyacrylamide (PHPA) polymer. When mixed with fresh water, a small quantity of Bore Drill P stabilizing agent can provide a clear, solid-free, viscous borehole stabilizing fluid for use in drilled shaft, auger drilling, horizontal directional boring, trenching excavation and reverse circulation (RC) rotary drilling. Bore Drill P stabilizing agent is not designed to be used in conjunction with bentonite based fluids (Gel).


  • Efficient shale/clay stabilizer and viscosifier
  • Does not require solids control unit to clean the slurry
  • Helps maintain a stable and gauge borehole
  • Helps maximize skin friction and ultimate end bearing capacity for a drilled shaft
  • Non-fermenting
  • No petroleum distillates involved
  • Can be broken down chemically with bleach (sodium hypochlorite)


Appearance                              white granular

Bulk density, lb/ft3                  52

pH (0.25% solution)                 8.5 to 9.0


  • Build a clay-free boring fluid
  • Stabilize reactive clay and shale formations
  • Enhance core recovery in continuous wireline coring operations
  • Provide high cohesiveness to bind excavated sandy soil and gravel
  • Removal of drilled spoils from augers and increase excavation rate
  • Maximize load transfer for drilled shaft application



  • 1-2 Pound of Bore Drill P will treat 100 gallons of water

Recommended Fluid Formulation for clay (Per 500 Gal)

  • 2 LBS Soda Ash
