Loresco type SWK® has particle sizes ranging from 0.1 to 12mm. 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. 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.


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