    POLY-BORE™ PLUS

    Borehole Stabilizing Dry Polymer

    Description POLY-BORE™ PLUS stabilizing agent is a free flowing, water-soluble,


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

    Applications/Functions The use of POLY-BORE PLUS 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)

     NSF/ANSI Standard 60 certified

    Typical Properties  Appearance Yellow granular

     Bulk density, lb/ft3 52

     pH (0.25% solution) 8.5 to 9.0


    Recommended
    Construction Applications
    Treatment
     Add 3 to 10 pounds of POLY-BORE™ PLUS dry polymer per 1000
    gallons of fresh water (3.6 - 12 kg/m3) slowly through the hopper to
    facilitate uniform dispersion and water wetting of the polymer.
    (See general instructions listed below.)

    Flooded Reverse Circulation Drilling


     Add 0.3 to 1 pound of POLY-BORE PLUS dry polymer per 100
    gallons of fresh water (0.6 - 1.2 kg/m3) slowly through the hopper to
    facilitate uniform dispersion and water wetting of the polymer.
    (Assumes the use of a centrifugal pump to operate venture hopper)
    (See general instructions listed below.)

    General Instructions
     Once the required amount of POLY-BORE PLUS has been added
    through the hopper continue to circulate and agitate the total volume
    of the mixing system for one complete circulation of the volume of the
    active mixing system. This amount of time will depend on the actual
    flowrate of the pump used to mix with and its calculated recycle rate
    of the respective volume of fluid.
     At the completion of one circulation of the volume of the active mixing
    system shut down all pumps and allow the resultant polymer slurry to
    set static for 30 minutes to further hydrate.
     At the end of the 30 minute static hydration period initiate mixing
    pumps for the time required for one complete circulation of the
    volume of the active mixing system to carry out homogenization of
    the prepared slurry.
     Measure the marsh funnel viscosity of the resultant polymer slurry
    and adjust as necessary to meet required slurry specifications and/or
    recommendations.
     Pump prepared polymer slurry into active circulating system or to
    slurry storage tanks as necessary.

    Notes
     Due to the high molecular weight of POLY-BORE PLUS special
    attention should be paid to avoid excessive mixing at high shear
    rates due to the potential for shear degradation (reduction in
    viscosity) of the high molecular weight polymer.
     Reduce total hardness (as calcium) of make-up water by adding
    soda ash (sodium carbonate) at 0.5 to 1 pound per 100 gallons (0.6 -
    1.2 kg/m3) of make-up water.
     Make-up water used to mix POLY-BORE PLUS dry polymer should
    meet the following quality:
    - total chloride less than 1500 ppm (mg/L)
    - total hardness less than 150 ppm as calcium
    - total chlorine less than 50 ppm
    - water pH between 8.5 - 9.5
     POLY-BORE PLUS dry polymer can be chemically broken down with
    regular household liquid bleach (5% sodium hypochlorite). Use one
    gallon of liquid bleach per 100 gallons (10 liters/m3) of fluid
    formulated with POLY-BORE PLUS dry polymer. Do not use
    perfumed liquid bleach or solid calcium hypochlorite.

    Packaging POLY-BORE PLUS dry polymer is packaged in 14 lb (6.35-kg) or 35 lb


    (15.88-kg) resealable plastic containers.
