POLY-BORE™ stabilizing agent is a free flowing, water-soluble, easy mixing, 100% active, dry granular polymer. POLY-BORE stabilizing agent is a very high molecular weight partially hydrolyzed polyacrylamide (PHPA) polymer. When mixed with fresh water, a small quantity of POLY-BORE 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. POLY-BORE stabilizing agent is not designed to be used in conjunction with bentonite based fluids.

    The use of POLY-BORE dry polymer assists or promotes the following:
  • Build a clay-free boring fluid
  • Stabilize reactive clay and shale formations
  • Enhance core recovery in continous 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


  • Can disperse easily with minimal shear
  • fficient 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)
  • NSF/ANSI Standard 60 certified
