Sand Pac

Sand Pac is an easy mixing, water soluble, polymer supplied as a granular powder. Sand Pac is designed for preparation of viscous earth-reinforcing fluids or slurries for a variety of drilling, trenching, and walling applications in the geo-construction industry.


  • Can be mixed directly in the borehole or excavation
  • Stabilizes borehole while excavating; improves skin friction
  • Non-gelling, even at high viscosities, facilitating settlement of fines, and maintenance of a clean fluid
  • High cohesiveness to bind excavated soil and gravel
  • Improves loading and removal of spoils
  • Works well in both fresh and saltwater


Appearance:       Solid. Powder. Dust.
COLOR:               White
WEIGHT:            NA
ODOR:                 Odorless or no characteristic odor.
pH:                       6.5-8.0


Sand Pac is ideal for slurry trenching, diaphragm walls, drilled shafts/bored piles, and tunneling.


Treatment For 500 Gallons of Water

  • 5lbs of Sand Pac will treat 500 gallons of water, use Soda Ash to lower water hardness
  • Sand Pac should be used in addition to other Velocity Energy Services products

Excavation Treatment

Sand Pac should be mixed by sifting carefully into a stream of water directed into the excavation or an agitator mix tank. Make-up water should have a pH of 8-10; add 6 lbs SODA ASH per 1,000 gallons water.
