EZ-Seal

ONE SACK GROUTING AND PLUGGING MATERIAL

EZ-SEAL one-sack granular bentonite product is intended for use as an easily mixed grouting and plugging material.

  • One-sack product
  • Easy to mix and apply, just add fresh water
  • Flexibility in application rate and grout set time
  • Good structural integrity
  • Low permeability
  • No heat of hydration
  • Minimal depletion of grout level after emplacement
  • NSF/ANSI Standard 60 certified

 

APPLICATION

The use if EZ-SEAL bentonite assists or promotes the following:

  • Sealing or grouting of plastic and steel casings
  • Plugging abandoned boreholes and filling earthen cavities
  • Grouting of loops for ground source heat pumps
  • Reduction of lost circulation
  • Stabilization of broken and unconsolidated formations

 

TYPICAL PROPERTIES

Appearance: Bluish-tan granules
Volume, ft³/sack: 0.70
Thermal conductivity, btu/hr ft °F (watts/meter °C): 0.41 (0.70)
 

MIXING & HANDLING

Add one 50-lb (22.7 kg) sack of EZ-SEAL material to appropriate amount of make-up water to obtain the desired solids content:

% Solids grout 15 20 23
Water, gallons 33 24 20
Water, liters 125 91 76
Yield volume, gallons 35.3 26.3 22.3
Yield volume, liters 133.6 99.6 84.4

Once EZ-SEAL® bentonite is added to the mixing water, the slurry will have an “oatmeal consistency” containing un-yielded and partially hydrated bentonite granules. It is recommended the product be blended only long enough to gain suspension of the EZ-SEAL material. Immediately tremie the grout into place to allow the bentonite granules to hydrate and swell in situ. Do not over mix and do not use a centrifugal pump.

ADDITIONAL INFORMATION

  • The grouting material and method selected will depend upon the specific subsurface environment including all prevailing geological and hydrological factors and any existing regulatory requirements.
  • The use of bentonite may not be appropriate in environments where the formation water chemistry has a total hardness greater than 500 parts per million and/or a chloride content of greater than 1500 parts per million.

 

PACKAGING & CONTROLS

EZ-SEAL bentonite is packaged in 50-lb (22.7 kg) multiwall paper bags, containing 0.7 ft³ (0.02 m³).
