The particles of SWK exhibit a hard, round shape and are composed of almost solid carbon. The bulk density of SWK is seventy pounds per cubic foot, and the porosity is forty-four percent. 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:

• Have a reasonably clean ditch (design usually calls for a ditch one foot wide).
• Pour Loresco SWK in a continuous layer six inches deep (or as specified).
• Place anodes on top of SWK.
• Pour SWK in a continuous layer until anodes are covered by a six inch backfill cover (or as specified).
• Fill the remainder of the ditch as specified.

Vertical Installation Procedure:

• Have a reasonably clean hole (depth depending on soil resistivity).
• Place one foot of SWK in bottom of hole.
• Lower and center anode in proper position.
• Pour SWK over anode until design level is reached.
• Fill remainder of hole as design specifies.

Specifications:

• Bulk Density: 70 lbs. per cubic foot.
• Particle Sizing: Ranging from 0.1 to 12mm.

Shipping Data:
Loresco SWK is shipped in fifty (50) pound (22.7 kg) coated, woven polypropylene bags. SWK may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fifty bags per pallet. Proven export packaging is also available.
