Product Information for:

Loresco SWK® Impressed Current Backfill

SWK® is designed for use in surface impressed current systems and containerized anodes.

 

Loresco SWK ® .
Loresco type SWK® is designed specifically for impressed current surface and containerized anodes.

Description
Loresco SWK® is heavy and sinks readily in water or light mud. It can be installed by pouring around the anodes, and tamping is not necessary.

The particles of SWK® exhibit a hard, round shape and are composed of almost solid carbon. SWK® is a product designed specifically for use around anodes in the earth.

Its low resistivity enables intimate anode contact and assures that most electrolytic discharge will occur at the Backfill periphery. According to EPA-approved leacherate tests, SWK® meets all purity requirements for materials utilized in burial.

Installation
Loresco SWK® may be poured freely in dry applications. Tamping is not required. if SWK® is poured through water or light mud, the rate of pouring should not exceed the rate of SWK®’s wetting and sinking. The rate of pouring through water will be approximately one hundred pounds per two minutes.

  • Horizontal Installation Procedure
    1. Have a reasonably clean ditch (design usually calls for a ditch one foot wide).
    2. Pour Loresco SWK® in a continuous layer six inches deep (or as specified).
    3. Place anodes on top of SWK®.
    4. Pour SWK® in a continuous layer until anodes are covered by a six inch Backfill cover (or as specified).
    5. Fill the remainder of the ditch as specified.
  • Vertical Installation Procedure
    1. Have a reasonably clean hole (depth depending on soil resistivity).
    2. Place one foot of SWK® in bottom of hole.
    3. Lower and center anode in proper position.
    4. Pour SWK® over anode until design level is reached.
    5. Fill remainder of hole as design specifies.
