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. NSF/ANSI Standard 60 certified Applications/Functions 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
Advantages
- Can disperse easily with minimal shear
- 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)
Typical Properties
- Appearance: White granular
- Bulk density, lb/ft3: 52
- pH (0.25% solution): 8.5 to 9.0
